Thank you guys for tuning in! I do a lot of side work on Infiniti and nissan vehicles and this is a problem that is becoming more and more common. change your automatic transmission fluid and pray this doesn't happen to you as well
Hey Eric, I could use your help man. So I'm driving my 2005 g35 and first it hesitated going into 2 or 3 gear. Figured I was probably super low on trans fluid. I stop at store, put a quart in and then when. I started driving again. It went from 1st to 2nd gear and then going into 3rd it felt like It wouldn't catch. Then all of the sudden nothing.. No more going forward. Its rev'ing but no actual moving forward. Then I turn off the car. Turn it back on and it will start accelerating again. But again, 1st to 2nd It changes and going into 3rd just stops moving forward and only revs. I tried it a few times and same thing each time. I can get moving until it's about to hit 3rd gear and then just stops moving forward. Do you think I'm having same issue with valve body or could it be torque converter? I have no clue. If you could give me any help man, I'd really appreciate it
@@deadmoon7959 wow my car started doing that almost a year ago and I was at the mercy of these mechanics who claimed to change my trans but I believe they changed a part cause the trans looks the same as before but they told me like tens times car was ready when they did not even start on it. So the fix as far as they told me was to put another trans In
@@aloiba100 Yeah, Ive been tripping out, cause I can't afford to put a new trans in right now. So I was praying for any possibility that even if it was a tranny issue, it would hopefully be something that wasn't SO major critical, that if I attempted to do the repair myself here at the pad.. I wouldn't be able to get it done and fixed, on my own, with just my basic tools here in my garage.
I watched this like 4 times! I love seeing this type of in depth, technical information of the inner workings to our vehicles. It helps me to understand my car when it's talking to me. Hopefully we never have a heated conversation, LOL, but putting this type of info in the brain bank gives confidence for when i need to identify an issue if it arises. Thanks Eric, keep up the great vids!!! 🤙🤙
Well done technical!!! Very good job. With mine M35x I just replaced the whole valve body and TCM with a completely rebuilt one. That was the fix......did not have change the tyranny, like one shop was suggesting. Keep up the good work brother!!!💯👍
What were your symptoms? I’m about to take my valve body out and test it b4 the tranny. Mine won’t go into gear and seem like it’s loosing pressure but it was just driving right but happend and it doesn’t grind or knock
@@travisussery258 what code did you get I got code p1757 front brake solinoid only my Manuel mode is shifting horrible like if the trans is out . But I got a used Vavle body on OfferUp for 120 and hopefully it takes the code away. Did you ever get yours fixed?
@@jrserrano9396 yes I did replace my Vavle body and the front brake solinoid code came off. But the horrible shifting was another code that I had because it was the shifter, a circuit was out and it was causing the computer to not shift smooth so I just replaced my shifter, Vavle body and obviously drain and fill with 7 bottles of atf. Car was running better then ever after that and shifting smoother then ever.
I’ve done this job multiple times for friends and I just had them get a valve body from a few junk yards near me and it was quick and easy. One thing you have to make sure if you do change your valve body is that you have to check if you have a single or a triple plug trans because they have different valve body plugs.
Interesting, did you ever have any issues with needing to program the valve body? The reason I ask is because there's like 3 different types of valve bodies one of them has the TCM inside the cabin on early style 2003 G35. Somwhere in 2005 they changed again and later changed again in 2006
hey man did you ever see the issue where it boots tou out of manual mode? So you push it into ds, works for like 30s then boots you back into regular D drive, and you can't go back to manual mode until you restart the car. heard of that??
I just wanted to mention that these engines and transmissions are available by the dozens at importer salvage parts. I'm pretty sure you can get a trans for ~$300.
im guessing electrical power to the transmission via the main relay component. that happen to me... corrosion on connectors prevented the transmission from going into 3rd from second.
Worth mentioning that this fix only applies to later models 05 and up. 03 and early 04 models have the TCM located by the ECU on the passenger side in the cabin.
I have the same problem with my 2003 G35 couple. As I step down on the gas it jumps forward but don't take off. Is it a solution to this at any chance?
Would a bad tranny cause my car to stutter / choke on itself? So mine is an automatic and when i step on it the rpms get stuck at 2k then jump upwards and it runs well. It only happens when its completely warmed up
It shouldn't turn off or feel like it's turning off, in my experience when you have a bad transmission you will just experience a lot of shutter and harsh engagements aside from that the vehicle should idle the same or very close to 1k prm sometimes idle can go up and down since the computer in the transmission also Is used to for idling
Some of the shift solenoids are available separately from the valve body. I've seen them for about $50 each. Worth looking into if you have this problem.
@@RUSOBPK eBay got them, but u have to read the reviews before buying them. I bought the front brake and high and low reverse solenoids on eBay they are good quality hopefully this solves the issue of my g35.
I've been watching as many of these valve body/TCM/sensor videos and reading up since my '04 G35 coupe ck engine light came on a week ago (Code P1716). I've been having hard shift issues basically when it is cold, so have been going easy when cold. My opinion, the check engine light should have come on long ago. Since I'm no mechanic and do only "light" work on my car (female, but know some females can/will do much more), want to be up on the subject. Thanks for posting this detailed video, even though not my vehicle's code, it is all the same d&$m thing! Two days ago took my car to a mechanic with ck engine light illuminated (P1716 turbine revolution sensor). Got charged for a cleanup of TCM & Harness Connections and for a trans service--went home, car "rested" for a few hours, take off and same ck engine light & Code P1716! Obviously, mechanic could have done more to ensure a fix was absolute before pickup. Not happy about paying for a job that didn't address the problem, and was for not. Thank God for the internet or I'd be totally in the dark!
@@MrYogitron92 No! I believe it needs a rebuilt trans. The TCM is located inside the valve body in my car, as is in this video. I do not believe mechanics will typically do what this mechanic is doing. Plus, the trans is now slipping. Big sign it is going south! Just a matter of time and it will "seize up!!!" 😪😱 Love the car but I'm done!!!
@@deadmoon7959 I thought I just replied to your question but don't see it. If you didn't get it, I traded the car in because I didn't want to hassle with trying to sell it with a transmission issue.
I have a g35 04 sedan and im having the same probleam exacly what u said and im really tire of trying to fix it im about to just trade the car in or just buy another one cash i got the same code p1617
Man i did exactly this, changed all the solenoids and reinstalled the valve body, now the car wont even crank, dash will light up, but doesnt start, i didnt disconnect the battery when doing the work, i forgot, maybe that messed up something, any help?
I had this same problem 05 g35x sedan.. I tried soldering the metal contact point and it did not work. So I changed the transmission 3 times and had the same problem with different valve bodies, I ended up just selling the car.. I highly regret it cause that was my favorite car
Eric. How did you become so knowledgeable on the G and 350? Are you a mechanic or is it just a hobby for these cars? I’m so impressed every time I see another video. I literally check your videos before anyone else, if I am doing a project on my G 👍
Practice makes perfect. I've always owned nothing but nissan/Infiniti growing up without a father. I had to figure things out on my own,I consider myself a mechanic but didn't go to school for it. I appreciate you always commenting and giving support to my channel thank you!
Great video, do you have any experience with the valve body itself? I’m having an issue that I thought was solenoids or the tcm but they seem ok and I’m thinking it may be a stuck valve in the valve body.
I have a 2005 350 zI replaced the transmission moduler and sylinods all Tcm but it want go hold the program on my Tcm nor will go foward or reverse I’ve been fighting for nine months trying to figure this out please I beg u got any ideas plus in manual it’s in 4 th gear at start why is that it’s a automatic
When I shit reverse. Than I have to give acceleration to reverse and the the reverse gear gets engaged and if I give acceleration right away. it will give jerk. What's the problem?
@ERICSDIYGARAGE Nice job 👍🏾 you did still fix his major issue, he was worried about, so that tells you his solenoid(s) were the issue, when it shakes though is it in sport mode or just normal drive? Just curious to know maybe it doesn’t matter which position it is in, but still if in sport mode it’d be harder on the car, so I definitely agree with you on driving the car till the transmission goes out and then a full replacement, but also if he comfortable enough he can just swap it to manual too, I have an auto Infiniti too. I would like to know this though is what years have you noticed this issue with? And is it coupe or sedans mostly?
Yeah I'm glad that it's at least drivable now. And as far as transmission issues 2003 g35 coupe or sedan are good 2004 2005 2006 and 2007 g35 coupes have this issue as they get older the same goes for 350z and other vehicles with this transmission
@@ERICSDIYGARAGE I appreciate you for getting back to me and thank you for updating me on the years that have the issue, I’m glad to know I’m in the safe zone on that matter😊, l look forward to seeing more of your videos, can you also subscribe to my channel, I’m trying to promote my own G35 content as well and get it out to the Nissan/Infiniti Community
I have an '04/05 G35x. Apparently they are (early versions) prone to valve body/tcu issues. One reason is due to a failure in the tranny cooling line, where it passes through the lower radiator. Causes coolant and ATF to mix in transmission and engine. Mine had this very issue while doing 120 (km) down highway. Most forums say that if caught right away and no damage done to transmission itself, it can be repaired by replacing valve body/TCU. Although it's not a guarantee. My issue is solely with 5th gear/overdrive, where tranny doesn't want to shift into 5th. As such I'm at 3000rpm while doing 100km (60mph). Hoping the valve body/TCU swap will solve issues. Note I too get a weird vibration when using manual mode, putting tranny into 5th gear. At around 80-85km/hr
I have a g37 when i come to a complete stop sometimes the trany go in neutral and when i go over speedbumps the same i was told that i habe low fluid i chek it multiple times but the guy tell me to let the car warm up and put e brake and put it in drive then chek it i found that fluid was low
I have a g37 trans went out took it to Infiniti said it’s was valve body so I got it fixed but it had was hard time accelerating a week later and service engine light is back on do you think it was fixed or I need a new trans?
I would probably first check what codes you are having if it's anything relating to the transmission I will take it back to the dealership. When the valve body is goes out on these vehicles they usually cause some sort of damage to the transmission that's why it's better to just replace both parts
For some reason my g won’t let me use the manual mode at all I’m not sure why but it could be a short causing it to not go into 1st gear on manual mode can anyone help me solve the issue?
P1716 speed sensor on the trans valve body It doesn’t allow trans to engage in 4/5th Get from junkyard and splice new sensor or replace and reprogram valve body. Titan armada g35 350z There’s an a and b sensor is replace both if your not to sure
Hello, I had the same problem with jx35 of not not responding to going forward or backwards. But the diagnostic code comes with bank 1 do you think it’s actually the transmission problem cause that makes more sense
Hey man I'm currently throwing a p0744 and a p1744 you think it would be better to try and put the time into fixing them or do you think it's too severe and better off just swapping the transmission
Hey bro my names Gustavo if you remember but I came over to your crib recently to pick up a transmission and I’ve had this exact problem and with the solenoids so I installed the tranny I got from you and it also didn’t work I still can’t accelerate at all
Yes I remember. It's possible that your ecu maybe be at fault or a bad connection if you replaced the transmission and it's doing the same thing It's probably not the issue it's hard to say at that point you have to look further into the problem
A scan tool wont pin point the seleniod that is bad but it will give you a code that you can look into, and by looking up common problems, you can usually figure out the issue. For example, a p1757 shows that the seleniod function is erratic but that doesn't mean the sensor is bad. What usually happens is the wire that goes to the seleniod breaks apart and it will throw this code. Repairing the trace will fix the problem
I had my transmission rebuilt on 1/12/2022, and after 9K miles it threw P1767 last night. Same symptom - in D, foot off brake and car doesn't move. Give it some gas and it moves. Today it is acting fine, of course. Thankfully it is within warranty from shop, we'll see. I suspect the valve body. The shop is highly recommended for these transmissions as that is ALL they do. They were able to drop the trans, rebuild the trans, reinstalled and tested in 2 days...so I have confidence they know what they are doing. I'll come back with results.
@@elcompask4te835 yes... They replaced the valve body under warranty and found a bad ground strap. Then after a few weeks I found that weird things would happen after going through the carwash. Throw all kinds of codes, dash lights would light up, headlights would come on by themselves. Turns out the drain where the IPDM lives (behind the battery ) was clogged and was filling up with water, thus the IPDM was under water. Took a long time for the mech to find it as I steered him in the wrong direction by mentioning the carwash under spray and the recent transmission work. 6 hours of diagnostic time ugh I don't think the IPDM being under water had anything to do with the symptom, but maybe....
My Infiniti started changing gears bad today I put it on a scanner it came up no codes so I’m wondering if it’s my transmission fluid my slip light is on also with my vdc light not knowing if that maybe the problem
Hey man i have a 2005 Infiniti g35 coupe that I won’t rev it and wont move when i put it into drive or reverse I already replaced the pedal,throttle body and ecm from another g35 that i own and i still does the same thing but now it will let me rev it do u think is the transmission? It won’t throw no codes
It could be a transmission problem without looking at your car unfortunately I wouldn't be able to help. I would get a scanner thay reads transmission codes and do a idle and pedal relearn
Just started having this issue as well ever since I did a drain and fill with Nissan matic J. my transmission randomly has issues when downshifting at certain times trying to come to a complete stop. Doesn’t do it everytime, just random times. It kinda jerks. Has no issues upshifting to next gears or shifting whatsoever.. only downshifting. Maybe bad solenoids?
@@AuzsG35 yea honestly dude I think it might be the shift solenoid going bad perhaps. Can’t confirm with u on that 100% But I do know that most issues with the G35 cars will be the front brake solenoid circuit cracking and it’s why this happens. Could also be low on fluid which also causes jerking and gears to not work properly(slippage), so make sure to have the correct amount of fluid on the tranny. Bands wearing out, maybe the tcm dying, could be a fvck tons of reasons. I am the 3rd owner of my G coupe. So the previous two owners never had done a transmission fluid change for over 100,000 miles. Car currently has 112,000 now. When I changed the fluid for the 1st time, it was oxidized. More like a amber type color, which needed to be replaced ASAP. I just did another drain and fill for the 2nd time to get rid of the old yucky fluid. So 1st I used matic J, which I don’t recommend cause shit is too expensive for a qt. You’ll be paying 20$ on those. You’re better off using matic S as this has superseded matic J and it’s better. After the 2nd drain and fill, it honestly feels much better and smoother with the gears shifting than before. Downshifting has also improved in my case by a little as well. But most of the time when u start to experience some new issues with new fluid on the tranny, its because u prolly already have transmission issues in the first place but wasn’t aware because the old fluid was doing a good job covering the issue as it has more friction. Once the new fluid comes in it starts to clean shit out which can cause slippage and other issues. Clean fluid will 100% show u the existing problems that u wasn’t aware of. Usually it’s very risky to do a tranny fluid change on high mileage cars that has not really got it serviced before. But I decided to do it anyways and see what happens. Regardless having old, dirty, oxidized fluid will fvck up the tranny anyways cause it won’t disperse heat too well. Number 1 reason on why tranny dies. But if u want too u can do the same as me. Just do another d/f and see if it makes a difference. I’m planning to do another d/f for a 3rd time. But not now. I would never suggest getting a flush if u have never serviced ur tranny tho. Shit can deff mess up or completely kill it. Just do d/f multiple times and I think it should be fine and get better.
@@Carmizo_ yea I bought new motor and trans. Trans went out after 200 miles. it was leaking fluid so I filled it up and it didn’t like that. Fluid level was fine but I guess it doesn’t appreciate new fluid.
@@AuzsG35 yea dude never ever fill a motor or transmission up beyond what the owner manual tells u. If it tells u 5qt for engine oil. Don’t put more or less than that. If it says 12qt for tranny don’t put more than that or less than that. 100% accurate. If u had that leak, u should’ve been on top of it and got it fixed right away cause if u don’t then it’s going to rip a hole in ur pocket which I’m pretty sure it did. Now that u have ur new motor and trans, take care of her and she’ll take care of u. I’d recommend doing a oil change and filter for the motor every 3 months. That’s what I do. And for atf u can try doing it every 25,000-30,000 miles. U just don’t want the fluid to lose it’s red color. Hope the best for u my man.
@@Carmizo_ yea I’m just gonna manual swap. I just found out today it’s done so I’m over automatic. I’d sell it but I just put 3k into the motor. Trans was 400$ so might as well run away with my good motor then fuck with auto trans n waste time
I have an 04' G35 Coupe auto trans. Car has 160K miles and Got vehicle for next to nothing from a relative. Replaced coil packs as they are old ,car was running great & I let my Son use vehicle for past 9 months as he needed it for his graduate degree and internship and is now an Engineer .He needs a new car and now I'm left with a G35 that is slipping ,shifting gears weird ,and reverse take like 15 seconds to engage. It is scary to drive as I don't know if its gonna slip when I go to make a left with oncoming traffic approching! And I make sure to back into a parking space first so I know I can get out . Not really using car only for short essential trips. I feel the car is worth keeping as it is a NIJ RWD 285 HP v6 car. Would cost a good chunk of change to replace new.
@@ERICSDIYGARAGE Awesome .Thank you . I'm in S. Fl area .Car was used locally by middle aged female mostly so it wasnt modded or raced and beat like a lot of them . I will definitely find my own parts as I already got a $3K price just to rebuild this one ! My area is unfortunately full of scammers. Thanks again.
I drive a 2005 350 z doing the same thing not wanting to take off like a bat out of hell anymore it’s lagging and fixed brake in TCM front brake solenoid. But did u replace all the the outer solenoids to make it stop lagging on take off I’m just asking cause I screwed if have to replace whole tcm cause reprogramming is out of my price
I have an 06 G35 auto just replaced the TCM and direct clutch solenoid and now I'm getting code U1000 does the TCM need to be reprogrammed it is new Bosch.
Its possible that it's not compatible with your year vehicle. They need to be the same style or yes you will need to program it however some places can not do it right
@@ERICSDIYGARAGE thx for the quick reply I ordered the tcm with the same part no so hopefully it just needs to be reprogrammed and all plugs were the same.
Can you tell me where is the speed sensor is at on the 04 g35 coupe? I have the 5 speed automatic with what i call a manual mode.i dont know what its called.but i can shift thru gears myself or just leave it in drive if that makes any sense lol.
One more question my g has 180k miles and i want to drain and fill my transmission fluid cause its looking dark in color.would it be ok? I have a hard shift when the car is cold start and take off.
Hey man had a question , i swapped my engine on my 2006 g35 everything went back where it needed to be and ive got good ground, ive also installed a grounding kit and a new battery and a new starter but it just doesn’t wanna turn over or start it just clicks, i separated the transmission from the engine a little to see if thatd help and it did , it cranks now but no start , i pulled out a coil to make sure jts getting spark and its not , have any idea why?
You probably don't have the transmission aligned properly. Make sure that the engine rotates by using a breaker bad if it doesn't than you need to go back and check what's not installed correctly in the transmission
@MrGodmode5 Yes. Manually rotate engine over a few times, after transmission is all bolted up. Make sure to rotate engine clockwise. If tranny isn't lined up, motor will bind up as it rotates. If it rotates freely, you should be good. Also double check your shifter linkage. Make sure it's in same gear on both transmission AND shifter know in cabin. Quite often it gets bumped into a gear other than one you thought it was. (You can push it fully one direction then count " of clicks to determine gear position.) If it wasn't in same gear when connected it will prevent all from engaging (shift lock switch). Hope that all helps :)
Always check rotation after fitment ..can also check the flex plate is aligned with the crank sensor...flex plates in these are weak as all ever...make sure the transmission slides right on or somethings up..saw a guy once wrench his g35x trans down after aligning the dowels and he flattened the flex plate 😂 it looked 100% correct but needed to be re-aligned...shortly afterwards his car developed a grinding sound at startup that sounded like a stuck starter....ended up being the trans pump had taken damage during the squeeze...car drove fine but sounded clapped..ended up buying it for 3k and giving it a billet flex plate,new trans pump and transgo shift kit...
I have a 2006 Infiniti G35x Sedan, automatic, with 180k Miles. A couple of days ago my SERVICE ENGINE SOON light went on and when I turn on the car the A/T light flashes for a few seconds. The codes that came up was P1757 (Front Brakes Solenoid valve Circuit)When I start the car and put it in drive the car starts rolling. Then I apply gas and it drives for about 20 second then I feel a push in the transmission and when I press gas again it feels like something is pulling the car back. When I stop the car and let go of brake, it does not roll, I need to press gas and once rpm reach 2-2.5 the car starts rolling. When I floor it, rpm does not go over 3 and car accelerates very slowly. But once I put it in reverse, it drives fine. Please let me know what you think could be the issue and how much it may cost me (ball park) to get it fixed. Thanks in advance
If you have A P1757 you have a broken connection like the one shown in this video look up how to fix a p1757 your vavle body needs to come down, and the broken connection needs to be soldered
I have an 05 G35, I purchased the car knowing I had to get the TCM reprogrammed. Owner before me bought a valve body from Amazon, installed it, I took it to Infiniti for them to program it however they couldn’t because they said the TCM was already written. They said I can order one but it’s 1700, any alternative options?
It can be reprogrammed. it's not like the cv-ts or newer transmissions were once it programed to a vehicle it cant be written again. Get a used tcm from a salvage yard
Hey bro I’m watching your video rn as I do my solenoids. I finished but however when I went to crank my car it doesn’t crank and there’s no gear indicator, battery is good and everything. Do you have any suggestions?
There is a small lever on the side of the valve body that connects to a lever coming from the transmission if you don't have that installed correctly it could give you the problem that you have because the vehicle doesn't know that if it's in park or not so you're probably need to drop the pan down and see if that lever on the side is centered correctly
The one you can move fairly easily right? It is centered on the rod in the transmission. But also I went around one more time and noticed before I tried starting it up again, I took off the connectors that are next to the solenoids to clean and I put them on in the wrong order/direction. So do you think the wrong placement of wires shorted the TCM? Or is it a different problem
Update: Sorry to bring my problems here but I got it to turn on. It was just a fuse. However now after adding my fluid and bolting everything, my reverse feels really slow. The other ones seem fine, haven’t test driven tho but the short distance that I moved, it took a lot of gas for the car to go reverse. Any ideas? Another fuse or solenoid or what
👆👆👆 He's Right Ya Know!!! 😄😄😄 Full Disclosure; - I'm driving AT. But it was the most beautiful G35 I ever saw. I couldn't refuse the car. HAD to take it home with me. Even thought it was only, literally 25 yards from his garage to my garage!
Got the dreaded p1757! I removed the valve body, check the TCM didn’t see any broken wires put everything back together should I just order a re manufacture valve body cost $235 ..
I have an 06' G35 Coupe, with 49k miles. Last Oct at around 48k I had Nissan perform the factory recommended flush/change of the tranny fluid. I've read some pro's and con's of people saying NOOO, and some saying it's fine.....im here to tell you that it made my shifts (TipTronic mode) quicker, and tight. It feels really, really good. And got the report from the spent fluids, and all appears to be great! *Infiniti recommends this at 50k miles.
@@ERICSDIYGARAGE my g35 now has a problem with manual mode. It will not work after a while and will Automatically go back into D even when in stick is in manual mode. The code is p0745 so it’s one of the valve body solenoids. Do you know how much it would cost to get it replaced ?

@@josecuervooduran6978 what did you do ? I’m thinking about just switching the direct clutch solenoid like how he did and as he says in the video it fixed the original problem which was the car he was working on wouldn’t take off. For my car I have the code p1764
Should of replaced the tcm with the solenoids buddy. I got one I'm working and took a really good look at it.. The actual input sensor that sits on top of the tcm is burned up.. Don't know why but it's throwing all kinds of codes and it's got the same issues as that one your working on..
2005 Infiniti g35 coupe. I got a p1764 code. Direct clutch solenoid function. Ik this video old and not many ppl are watching. There’s not too many videos on this code or information. I was planning on just swapping the trans but if anyone knows if the better way to deal with this code is to replace the solenoids then I’ll try that nd save some money.

when I drive some times it doesn’t wanna shift so I let off then accelerate then it shifts
What does that mean

I don’t know about cars but watching this guy makes me feel like I know more now.
Well done technical!!! Very good job. With mine M35x I just replaced the whole valve body and TCM with a completely rebuilt one. That was the fix......did not have change the tyranny, like one shop was suggesting. Keep up the good work brother!!!💯👍
Where did you get your rebuilt valve body from?
What were your symptoms? I’m about to take my valve body out and test it b4 the tranny. Mine won’t go into gear and seem like it’s loosing pressure but it was just driving right but happend and it doesn’t grind or knock
@@travisussery258 what code did you get I got code p1757 front brake solinoid only my Manuel mode is shifting horrible like if the trans is out . But I got a used Vavle body on OfferUp for 120 and hopefully it takes the code away. Did you ever get yours fixed?
@@panchogomez4238did it work bro ?
@@jrserrano9396 yes I did replace my Vavle body and the front brake solinoid code came off. But the horrible shifting was another code that I had because it was the shifter, a circuit was out and it was causing the computer to not shift smooth so I just replaced my shifter, Vavle body and obviously drain and fill with 7 bottles of atf. Car was running better then ever after that and shifting smoother then ever.
Good video👍🏼
Failures are only a bad thing if we refuse to gain anything from them & in my mind any info is a gain. Thank you for the video.
I’ve done this job multiple times for friends and I just had them get a valve body from a few junk yards near me and it was quick and easy. One thing you have to make sure if you do change your valve body is that you have to check if you have a single or a triple plug trans because they have different valve body plugs.
Interesting, did you ever have any issues with needing to program the valve body? The reason I ask is because there's like 3 different types of valve bodies one of them has the TCM inside the cabin on early style 2003 G35. Somwhere in 2005 they changed again and later changed again in 2006
hey man did you ever see the issue where it boots tou out of manual mode? So you push it into ds, works for like 30s then boots you back into regular D drive, and you can't go back to manual mode until you restart the car. heard of that??
Wondering if u need to reprogram
As the other guy asked which trans need reprogrammed. Used units don't I've heard and new units do. Which is it ? No one online seems to truly know.
when I drive some times it doesn’t wanna shift so I let off then accelerate then it shifts
I just wanted to mention that these engines and transmissions are available by the dozens at importer salvage parts. I'm pretty sure you can get a trans for ~$300.

No you can't get them that cheap
Check your ground wires. Had the same problem until I re-loomed the harness. Worked for me.
That's what I was thinking too. Sounds like could be a ground getting loose.
Where are all the ground wires located?

Bro you just saved my life I replaced the front brake solenoid and forgot how the bolts went to hold the whole solenoid valve
Glad to help
how did you do this? my 06 g35 sedan is throwing a front brake solenoid code
Crazy! That's why I do transmission fluid changes every 30-40k miles.
I have P1730 is that the same thing as these codes?
im guessing electrical power to the transmission via the main relay component. that happen to me... corrosion on connectors prevented the transmission from going into 3rd from second.
Worth mentioning that this fix only applies to later models 05 and up. 03 and early 04 models have the TCM located by the ECU on the passenger side in the cabin.
2003-2004 transmissions are usually built better and done have these types of issues but they yes are different
Do you know where the vehicle speed sensor would be located? Code P0500 speedometer doesn't work 2004 g35 coupe automatic transmission.
I have the same problem with my 2003 G35 couple. As I step down on the gas it jumps forward but don't take off. Is it a solution to this at any chance?
Would a bad tranny cause my car to stutter / choke on itself?
So mine is an automatic and when i step on it the rpms get stuck at 2k then jump upwards and it runs well. It only happens when its completely warmed up
It shouldn't turn off or feel like it's turning off, in my experience when you have a bad transmission you will just experience a lot of shutter and harsh engagements aside from that the vehicle should idle the same or very close to 1k prm sometimes idle can go up and down since the computer in the transmission also Is used to for idling
wowwww I had the SAME exact problem with my g35 2005, I tried what you did but ended up needing a new transmission
Did you go with a used unit?
No codes but when I start the car and put it from park to drive it hesitates a bit b4 it feels like it grabs it's a 07 G35 sedan
I just bought a good used valve body for $220. Done. One solenoid was weak. I jumped it and put power to it. It was weak.
Some of the shift solenoids are available separately from the valve body. I've seen them for about $50 each. Worth looking into if you have this problem.
Any idea how i can look for them? Been trying but can only find complete kits
@@RUSOBPK I've seen them on Rockauto for the 5 speed. Not sure if they're still available. For the 7 speed is hard to find.

I've been watching as many of these valve body/TCM/sensor videos and reading up since my '04 G35 coupe ck engine light came on a week ago (Code P1716). I've been having hard shift issues basically when it is cold, so have been going easy when cold. My opinion, the check engine light should have come on long ago. Since I'm no mechanic and do only "light" work on my car (female, but know some females can/will do much more), want to be up on the subject. Thanks for posting this detailed video, even though not my vehicle's code, it is all the same d&$m thing!
Two days ago took my car to a mechanic with ck engine light illuminated (P1716 turbine revolution sensor). Got charged for a cleanup of TCM & Harness Connections and for a trans service--went home, car "rested" for a few hours, take off and same ck engine light & Code P1716! Obviously, mechanic could have done more to ensure a fix was absolute before pickup. Not happy about paying for a job that didn't address the problem, and was for not. Thank God for the internet or I'd be totally in the dark!
Ever got 1716 fixed?
@@MrYogitron92 No! I believe it needs a rebuilt trans. The TCM is located inside the valve body in my car, as is in this video.

Great video, do you have any experience with the valve body itself? I’m having an issue that I thought was solenoids or the tcm but they seem ok and I’m thinking it may be a stuck valve in the valve body.
As far as rebuilding no sorry
I have a 2005 350 zI replaced the transmission moduler and sylinods all Tcm but it want go hold the program on my Tcm nor will go foward or reverse I’ve been fighting for nine months trying to figure this out please I beg u got any ideas plus in manual it’s in 4 th gear at start why is that it’s a automatic
I changed my at transmission fluid a few months ago now my car hesitates to go into reverse after it warms up.
how much fluid is need to fill the torque converter ? Any idea, making may math I think is like 2 and a half but no sure.
Its about 3 but it will only take about 8 to fill the transmission and torque converter
where did you get your solenoids
SMe thing happend to my 06 fx35 ended up just replacing the TCM
When I shit reverse. Than I have to give acceleration to reverse and the the reverse gear gets engaged and if I give acceleration right away. it will give jerk. What's the problem?
did you check the harnesses to the tcm I hear ppl accidentally swap them

What are tboes two sensors that sit under the pan called????
@ERICSDIYGARAGE Nice job 👍🏾 you did still fix his major issue, he was worried about, so that tells you his solenoid(s) were the issue, when it shakes though is it in sport mode or just normal drive? Just curious to know maybe it doesn’t matter which position it is in, but still if in sport mode it’d be harder on the car, so I definitely agree with you on driving the car till the transmission goes out and then a full replacement, but also if he comfortable enough he can just swap it to manual too, I have an auto Infiniti too. I would like to know this though is what years have you noticed this issue with? And is it coupe or sedans mostly?
Yeah I'm glad that it's at least drivable now. And as far as transmission issues 2003 g35 coupe or sedan are good 2004 2005 2006 and 2007 g35 coupes have this issue as they get older the same goes for 350z and other vehicles with this transmission
@@ERICSDIYGARAGE I appreciate you for getting back to me and thank you for updating me on the years that have the issue, I’m glad to know I’m in the safe zone on that matter😊, l look forward to seeing more of your videos, can you also subscribe to my channel, I’m trying to promote my own G35 content as well and get it out to the Nissan/Infiniti Community
I have an '04/05 G35x. Apparently they are (early versions) prone to valve body/tcu issues. One reason is due to a failure in the tranny cooling line, where it passes through the lower radiator. Causes coolant and ATF to mix in transmission and engine. Mine had this very issue while doing 120 (km) down highway.
Most forums say that if caught right away and no damage done to transmission itself, it can be repaired by replacing valve body/TCU. Although it's not a guarantee.
My issue is solely with 5th gear/overdrive, where tranny doesn't want to shift into 5th. As such I'm at 3000rpm while doing 100km (60mph). Hoping the valve body/TCU swap will solve issues.
Note I too get a weird vibration when using manual mode, putting tranny into 5th gear. At around 80-85km/hr
can I use the valve body off a 07 350z to replace my valve body on my 07 g35
2:55 I was like it's the 19mm. Lol
I have a g37 when i come to a complete stop sometimes the trany go in neutral and when i go over speedbumps the same i was told that i habe low fluid i chek it multiple times but the guy tell me to let the car warm up and put e brake and put it in drive then chek it i found that fluid was low
I just picked up a 05 Sedan with 234k and just changed the fluid cuz it looked brown. Hopefully it runs strong going forward!
How’s it been treating you ?
@@om4r69 I sold it, fun when it ran good.
I have a g37 trans went out took it to Infiniti said it’s was valve body so I got it fixed but it had was hard time accelerating a week later and service engine light is back on do you think it was fixed or I need a new trans?
I would probably first check what codes you are having if it's anything relating to the transmission I will take it back to the dealership. When the valve body is goes out on these vehicles they usually cause some sort of damage to the transmission that's why it's better to just replace both parts
I have fixed crank sensor 2 cranks is a one transmission swap everything I just need a transmission next

My fx shifts super smooth? But I have a po745 code do you think I have a bad connection somewhere? Thanks 👍
If it's p1757 eventually you'll have little to no pressure
Hello, I had the same problem with jx35 of not not responding to going forward or backwards. But the diagnostic code comes with bank 1 do you think it’s actually the transmission problem cause that makes more sense
You would need to provide more info like the actual code. You need a decent scan tool to read transmission codes so it's possible
I have a p0725 code, car shifts hard from 1st to 3rd. What could it be?
It is a transmission speed sensor at time 7:00
My torque converter is stuck to the flywheel and I can’t turn it to get the other bolt off any help
You won't be able to remove the torque converter without turning the engine over by hand
Hey man I'm currently throwing a p0744 and a p1744 you think it would be better to try and put the time into fixing them or do you think it's too severe and better off just swapping the transmission
It will probably be cheaper to just get a different transmission with the different torque converter
So how many quarts of fluid did you add back after draining the fluid
Did you ever find out how much?
Hey bro my names Gustavo if you remember but I came over to your crib recently to pick up a transmission and I’ve had this exact problem and with the solenoids so I installed the tranny I got from you and it also didn’t work I still can’t accelerate at all
Yes I remember. It's possible that your ecu maybe be at fault or a bad connection if you replaced the transmission and it's doing the same thing It's probably not the issue it's hard to say at that point you have to look further into the problem
How did you determine what selenoid had the codes, does a scanner tell you ?
A scan tool wont pin point the seleniod that is bad but it will give you a code that you can look into, and by looking up common problems, you can usually figure out the issue. For example, a p1757 shows that the seleniod function is erratic but that doesn't mean the sensor is bad. What usually happens is the wire that goes to the seleniod breaks apart and it will throw this code. Repairing the trace will fix the problem
Can someone link for a Direct clutch solenoid??? 04 G35x
I had my transmission rebuilt on 1/12/2022, and after 9K miles it threw P1767 last night. Same symptom - in D, foot off brake and car doesn't move. Give it some gas and it moves.
Today it is acting fine, of course.
Thankfully it is within warranty from shop, we'll see. I suspect the valve body. The shop is highly recommended for these transmissions as that is ALL they do. They were able to drop the trans, rebuild the trans, reinstalled and tested in 2 days...so I have confidence they know what they are doing.
I'll come back with results.
@CFauvel any update bro?
@@elcompask4te835 yes...
They replaced the valve body under warranty and found a bad ground strap.
Then after a few weeks I found that weird things would happen after going through the carwash. Throw all kinds of codes, dash lights would light up, headlights would come on by themselves. Turns out the drain where the IPDM lives (behind the battery ) was clogged and was filling up with water, thus the IPDM was under water. Took a long time for the mech to find it as I steered him in the wrong direction by mentioning the carwash under spray and the recent transmission work. 6 hours of diagnostic time ugh
I don't think the IPDM being under water had anything to do with the symptom, but maybe....
Will it be in the transmission also in a 2003 350z A/T? Or would it be under the passenger dash
It could be either one depending on the plug type. Jack up the car if you see 3 plugs by the transmission it will be in the cabin
Does anybody know how many qrts of atf fluid goes back in after Vavle body removal for g35 08 5spd??
Around 8
My Infiniti started changing gears bad today I put it on a scanner it came up no codes so I’m wondering if it’s my transmission fluid my slip light is on also with my vdc light not knowing if that maybe the problem
Get a good scanner that can read transmission codes
Yo brotha I have a code p0735 which is a gear 5 incorrect ratio. What do you recommend i should do? I havent changed the fluid so is possible if that?
Hey brother got the same code did you figure it out?
Try removing the transmission pan and checking the screen/filter if it's dirty, that could be the issue. I've seen that code with clogged filters
Hey man i have a 2005 Infiniti g35 coupe that I won’t rev it and wont move when i put it into drive or reverse I already replaced the pedal,throttle body and ecm from another g35 that i own and i still does the same thing but now it will let me rev it do u think is the transmission? It won’t throw no codes
It could be a transmission problem without looking at your car unfortunately I wouldn't be able to help. I would get a scanner thay reads transmission codes and do a idle and pedal relearn
Just started having this issue as well ever since I did a drain and fill with Nissan matic J. my transmission randomly has issues when downshifting at certain times trying to come to a complete stop. Doesn’t do it everytime, just random times. It kinda jerks. Has no issues upshifting to next gears or shifting whatsoever.. only downshifting. Maybe bad solenoids?
Mines basically the same but it doesn’t shift up.
@@AuzsG35 yea honestly dude I think it might be the shift solenoid going bad perhaps. Can’t confirm with u on that 100% But I do know that most issues with the G35 cars will be the front brake solenoid circuit cracking and it’s why this happens. Could also be low on fluid which also causes jerking and gears to not work properly(slippage), so make sure to have the correct amount of fluid on the tranny. Bands wearing out, maybe the tcm dying, could be a fvck tons of reasons. I am the 3rd owner of my G coupe. So the previous two owners never had done a transmission fluid change for over 100,000 miles. Car currently has 112,000 now. When I changed the fluid for the 1st time, it was oxidized. More like a amber type color, which needed to be replaced ASAP. I just did another drain and fill for the 2nd time to get rid of the old yucky fluid. So 1st I used matic J, which I don’t recommend cause shit is too expensive for a qt. You’ll be paying 20$ on those. You’re better off using matic S as this has superseded matic J and it’s better. After the 2nd drain and fill, it honestly feels much better and smoother with the gears shifting than before. Downshifting has also improved in my case by a little as well. But most of the time when u start to experience some new issues with new fluid on the tranny, its because u prolly already have transmission issues in the first place but wasn’t aware because the old fluid was doing a good job covering the issue as it has more friction. Once the new fluid comes in it starts to clean shit out which can cause slippage and other issues. Clean fluid will 100% show u the existing problems that u wasn’t aware of. Usually it’s very risky to do a tranny fluid change on high mileage cars that has not really got it serviced before. But I decided to do it anyways and see what happens. Regardless having old, dirty, oxidized fluid will fvck up the tranny anyways cause it won’t disperse heat too well. Number 1 reason on why tranny dies. But if u want too u can do the same as me. Just do another d/f and see if it makes a difference. I’m planning to do another d/f for a 3rd time. But not now. I would never suggest getting a flush if u have never serviced ur tranny tho. Shit can deff mess up or completely kill it. Just do d/f multiple times and I think it should be fine and get better.
@@Carmizo_ yea I bought new motor and trans. Trans went out after 200 miles. it was leaking fluid so I filled it up and it didn’t like that. Fluid level was fine but I guess it doesn’t appreciate new fluid.
@@AuzsG35 yea dude never ever fill a motor or transmission up beyond what the owner manual tells u. If it tells u 5qt for engine oil. Don’t put more or less than that. If it says 12qt for tranny don’t put more than that or less than that. 100% accurate. If u had that leak, u should’ve been on top of it and got it fixed right away cause if u don’t then it’s going to rip a hole in ur pocket which I’m pretty sure it did. Now that u have ur new motor and trans, take care of her and she’ll take care of u. I’d recommend doing a oil change and filter for the motor every 3 months. That’s what I do. And for atf u can try doing it every 25,000-30,000 miles. U just don’t want the fluid to lose it’s red color. Hope the best for u my man.
@@Carmizo_ yea I’m just gonna manual swap. I just found out today it’s done so I’m over automatic. I’d sell it but I just put 3k into the motor. Trans was 400$ so might as well run away with my good motor then fuck with auto trans n waste time

You probably don't have the transmission aligned properly. Make sure that the engine rotates by using a breaker bad if it doesn't than you need to go back and check what's not installed correctly in the transmission
@@ERICSDIYGARAGE ill do this first thing in the morning! any tips on how to know when its lined up correctly? Before closing it up?
@MrGodmode5 Yes. Manually rotate engine over a few times, after transmission is all bolted up. Make sure to rotate engine clockwise. If tranny isn't lined up, motor will bind up as it rotates.
If it rotates freely, you should be good. Also double check your shifter linkage. Make sure it's in same gear on both transmission AND shifter know in cabin. Quite often it gets bumped into a gear other than one you thought it was. (You can push it fully one direction then count " of clicks to determine gear position.) If it wasn't in same gear when connected it will prevent all from engaging (shift lock switch).
Hope that all helps :)
Always check rotation after fitment ..can also check the flex plate is aligned with the crank sensor...flex plates in these are weak as all ever...make sure the transmission slides right on or somethings up..saw a guy once wrench his g35x trans down after aligning the dowels and he flattened the flex plate 😂 it looked 100% correct but needed to be re-aligned...shortly afterwards his car developed a grinding sound at startup that sounded like a stuck starter....ended up being the trans pump had taken damage during the squeeze...car drove fine but sounded clapped..ended up buying it for 3k and giving it a billet flex plate,new trans pump and transgo shift kit...
I have a 2006 Infiniti G35x Sedan, automatic, with 180k Miles. A couple of days ago my SERVICE ENGINE SOON light went on and when I turn on the car the A/T light flashes for a few seconds. The codes that came up was P1757 (Front Brakes Solenoid valve Circuit)When I start the car and put it in drive the car starts rolling. Then I apply gas and it drives for about 20 second then I feel a push in the transmission and when I press gas again it feels like something is pulling the car back. When I stop the car and let go of brake, it does not roll, I need to press gas and once rpm reach 2-2.5 the car starts rolling. When I floor it, rpm does not go over 3 and car accelerates very slowly. But once I put it in reverse, it drives fine. Please let me know what you think could be the issue and how much it may cost me (ball park) to get it fixed. Thanks in advance

There is a small lever on the side of the valve body that connects to a lever coming from the transmission if you don't have that installed correctly it could give you the problem that you have because the vehicle doesn't know that if it's in park or not so you're probably need to drop the pan down and see if that lever on the side is centered correctly
The one you can move fairly easily right? It is centered on the rod in the transmission. But also I went around one more time and noticed before I tried starting it up again, I took off the connectors that are next to the solenoids to clean and I put them on in the wrong order/direction. So do you think the wrong placement of wires shorted the TCM? Or is it a different problem
Update: Sorry to bring my problems here but I got it to turn on. It was just a fuse. However now after adding my fluid and bolting everything, my reverse feels really slow. The other ones seem fine, haven’t test driven tho but the short distance that I moved, it took a lot of gas for the car to go reverse. Any ideas? Another fuse or solenoid or what
We're u from ?
So basically just replacjng the rubber with the 10mm?
Not sure what you are referring to
stick won’t break unless you do it yourself
👆👆👆 He's Right Ya Know!!! 😄😄😄
Full Disclosure; - I'm driving AT. But it was the most beautiful G35 I ever saw. I couldn't refuse the car. HAD to take it home with me. Even thought it was only, literally 25 yards from his garage to my garage!
Got the dreaded p1757!
I removed the valve body, check the TCM didn’t see any broken wires put everything back together should I just order a re manufacture valve body cost $235 ..
I've heard good and bad you might need to program it to your vehicle
@@ERICSDIYGARAGE should I just replace all the solenoids instead of replacing the entire valve body?
@@jessiecabrera8171 your going to spend more on just replacing the selenoids
@@ERICSDIYGARAGE ok, my only concern is who would I take it to IF I need to program the new valve body?

which sensor is the temperature fluid sensor?
It's a small two wire sensor and it's held down by 1 10mm
My auto g35 is ok but it has a bit if a lag when shifting in manual mode.
Some lag is normal but if its's excessive try to change your fluid with oem nissan it might help
I have an 06' G35 Coupe, with 49k miles. Last Oct at around 48k I had Nissan perform the factory recommended flush/change of the tranny fluid. I've read some pro's and con's of people saying NOOO, and some saying it's fine.....im here to tell you that it made my shifts (TipTronic mode) quicker, and tight. It feels really, really good. And got the report from the spent fluids, and all appears to be great!
*Infiniti recommends this at 50k miles.
@@ERICSDIYGARAGE my g35 now has a problem with manual mode. It will not work after a while and will Automatically go back into D even when in stick is in manual mode. The code is p0745 so it’s one of the valve body solenoids. Do you know how much it would cost to get it replaced ?
my g just started doing exactly this, the car doesn’t go when i press the gas feels like i’m in neutral till about 2000rpms and then it starts to go, im hoping i don’t need a new transmission 😭😭🙏i just bought this car last week and i can’t even enjoy driving it, it’s so heartbreaking spending money on it and having problems right around the corner, any tips on fixing this problem
Having same problem what did you do?
@@josecuervooduran6978 me too just recently
@@josecuervooduran6978 what did you do ? I’m thinking about just switching the direct clutch solenoid like how he did and as he says in the video it fixed the original problem which was the car he was working on wouldn’t take off. For my car I have the code p1764

Does this apply to the 06 Nissan titan
Yes
Does it have to be re programmed if you’re installing a new valvebody??
If it's new yes I believe it will need to be programmed to the vehicle
Does it have to be programmed
@angmccarty4621 if it's completely new yes it will need to be
I put it back in bro but now my car only reads neutral and won’t even go into park, if anyone can help I’d appreciate it
forgot to pull up something
no its the intake its not much of a problem its getting to much air in the engine check his intake rubbers and tubes
Should of replaced the tcm with the solenoids buddy. I got one I'm working and took a really good look at it.. The actual input sensor that sits on top of the tcm is burned up.. Don't know why but it's throwing all kinds of codes and it's got the same issues as that one your working on..
Most people won't sell just the tcm since without it the transmission is worthless
@@ERICSDIYGARAGE solenoids and tcm came all together eBay buddy pulled the solenoids and got it going again.
2005 Infiniti g35 coupe. I got a p1764 code. Direct clutch solenoid function. Ik this video old and not many ppl are watching. There’s not too many videos on this code or information. I was planning on just swapping the trans but if anyone knows if the better way to deal with this code is to replace the solenoids then I’ll try that nd save some money.
I've been able to drop the valve body and remove the solenoids, and clean the valve body with compresed air and it fixed my problem
Hi man, my 350z Nissan 2004 automatic throw a code P0720. Just change all fluid and replace the filter then i got this. Any idea.
Make sure you filled the transmission with the correct amount of fluid
@@ERICSDIYGARAGE thank you Eric, knowing
@@ERICSDIYGARAGE reading that its a pain in the ass.
@@ERICSDIYGARAGE do I have to runthe car or with it cool can check
@@ERICSDIYGARAGE Eric check the fluid level and ore ok, the technician said that I need a new valve body, because water got into the tranny.
Most people want to know which trans need reprogrammed. Used units don't I've heard and new units do. Which is it ? No one online seems to truly know.
New units
I have code p1754 and p1764 what should I do I have an extra transmission
Try changing selenoids if that doesn't help you will need a new vavle body
@@ERICSDIYGARAGE should I just install my other transmission
Yes or just change the vavle body
I got a transmission issue on my '08 G35x where it seems to be stuck in 4th gear and wont come out of that gear. Anyone know what that could be? Thanks in advance
it's 1757
Yes it's possible I would check for pending codes
@@ERICSDIYGARAGE i'm having the same issue too should i just replace the entire valve body and tcm ?
@kaamfinitii if it's a p1757 it's fixable and if done right, it will be a permanent fox
@@ERICSDIYGARAGE damn i was just quoted $1500 i just gotta hope and pray
Changing the Trans fluid probably cause this
No the problem started slowly getting worse over time before I even removed the fluid
Can I buy the solenoids ?
I'm sure you can find them online but I've never tried
Another reason why to get a manual transmission When buying a G
Be patient and try to find a manual transmission G/Z. Driving an automatic sports car is not fun 🙅♂️
It is fun
Hay q programarla.???
No
What about code p1716?
The sensor is in tail end of the transmission and will need to be disassembled
@@ERICSDIYGARAGE do you think it’s better buying a new transmission rather than fixing it or do you recomend fixing it?
@stoner420b8 yes, but hold on to your tcm from your old transmission
