6L90 Torque Converter Install in an 6L80 Transmission - Silverado Sierra Tahoe Suburban Yukon
VloĹžit
- Äas pĹidĂĄn 14. 01. 2021
- In this video we show how to install a 6L90 torque converter in the 6L80 transmission in my 2014 Silverado.
The 6L90 torque converter was used in some 5th gen ZL1 Camaros and some CTS-Vs.
I made this swap because of the well documented issues with the 6L80 torque converters failing, and damaging the transmission by clogging the pump with debris.
We did locate the following article which indicates that the 6L90 torque converters may be prone to the same issue but we will see how this one holds up over time.
www.sonnax.com/tech_resources...
The 6L80 transmission is used across the lineup of GM vehicles including but not limited to: Chevy
SS, Silverado, Tahoe, Suburban, Yukon, Sierra, and more.
NOTE: you will need to add additional fluid once the torque converter is installed.

Really nice to see you guys getting the truck back together after all this time.
Getting there! Definitely took a lot longer than planned
Your DOD delete video series and other videos related to that truck have helped greatly. Thank you for taking time to make helpful content
Very welcome!
Great video. I had that same issue of transmission shudder in my 2017 Sierra at 30K miles. The dealer replaced the fluid. It happened again at 57K miles and this time they replaced the torque converter. I was glad I purchased the 100K power train warranty when I bought the truck, I have 10 months left on it!
lol this comment was exactly 10 months ago. Hopefully you are having no issues
Love your videos man. I plan to do the same DOD/AFM delete to my truck by following along your videos. Definitely going to look into a torque converter swap now too
Awesome! Glad they have been helpful!!
After seeing this video me too. Iâm pulling my 5.3 in a few months and I will definitely be replacing that torque converter while the motor is out.
Definitely a good idea. If you want even stronger, go with a billet converter.
@@TheSundaeDrive where did you get the converter
I have a link in the description but I got it through my local dealership
Thank u for the video. About to do my first converter change. Went out at about 160k miles. Gonna use the amsoil as well.
Glad it helped! Good luck with the swap
Confirmed! My TCC failed with 108k on the clock in my '17. Went with a reman trans. It is my belief that the AFM operation makes the TCC work much harder and thus reduces its already short life.
Seems like I got mine swapped out just in time!
You should have replaced the Front Seal as well!
I believe that as well. Also contributes to the known cylinder misfire due to stuck lifter issue. I bought a $60 device to plug in the OBD port that disables the AFM and man does it ever respond better.
Great video and information. My TC failed at 82K miles and shredded my transmission. Fortunately for me my 2014 was still under its 100k mile powertrain warranty so I had it repaired for free though it took two and a half weeks. My transmission was so trashed I actually got a new one and not a reman. I also got the upgraded TC installed as well at no cost to me.
Always nice when the warranty comes through!
Which truck have 6l90 or every truck have 6l80. Thank you
im at 113K miles on my 2016 Sierra and i think my TC and tans are toast, I was able to get a trans off a 2018 silverado LT with 5K miles on it (same 6L80 trans). The truck was totaled but trans still good. planning on doing the swap in a week. my questions are: do you think any programming/relearn is required for the whole trans swap? secondly, while its down should i upgrade the torque converter or just use the OEM?
@@utrocker7 I would definitely upgrade the TC. That's what caused my trans to fail. As for the programming, my guess is it will need to be reprogrammed or at least a relearn for sure.
I agree with Michael
Great video! Thanks for this solution. My 6L80 blew at 138,000. Thanks GM đ
That stinks đ
My 6l90 in a 2017 2500 grenaded at 80k,cost me 5800 for a complete new tranny
Iâm at 150k on the stock trans. đŹ
Excellent video sir, very valuable footage to have access to.
Glad to help!
@The Sundae Drive, thank you very much for this & your other instructional videos, very helpful!! I have a 6L80 transmission in my 2010 Chevy Avalanche 5.3L, but my TC hasn't failed yet (~130K). Questions: 1) Do you know how much of a different a billet makes - and is your answer based on what you're driving/towing, or overall longevity? 2) RockAuto suggests for me: TC Remfg. B85JMBX (Standard), HDB85JMBX (Heavy-Duty Billet), or B85JMBXF (Flanged Hub). I was considering one of those, but after referring to your 6L80/6L90 article, sounds like I probably shouldn't consider those for replacements? 3) I saw another guy suggests getting a L6-80 (made for Corvette C5) - did you ever look into that? (I'm basically wondering what sold you on the GM 6L90 (24242552)? Thanks!!
Thank you for this video - have a 6L90E in mine, but mileage is quite low so far.
Am surprised you didn't change out the front main seal of the transmission - it's right there, and super cheap and convenient at that stage =)
Generally you don't mess with rear mains unless they're leaking. Better off keeping it sealed because it's hard to get a good seal replacing it.
We do that with Allison builds. If the rear main is good, it stays
@TheSundaeDrive what do you think?
Thanks Cliff, this is great information to know.
Glad to help!
Awesome video I wish Iâve seen this a few months back bc my trans took a shit
Glad to help! Hopefully it will help prevent another failure for you!
147đ's up thanks again for taking us all along with you
how much torque and horsepower is lost going through the 4L80E transfer case in 410 truck rear end before the power gets to the ground that is a growing question I'd like to know
The ZL1 converter has a dual disc lockup clutch, and should have a slightly higher stall speed. Pop a new seal in the front of your trans since you are there! Pack the seal lip with grease, apply some lube to the torque converter shaft OD, and let er' rip. Thanks for the vid.
good tips!
Do you have a part number for that converter? Iâm looking at one myself.
great video, do you know what the difference in the stall speeds are between the 2?
I got 195,099 miles out of mine. But it went full self destruct within 15 milesâŚ. Started to feel a little bit of a slip.. then started up a pretty good grade and it literally started screaming, and I lost all but 1 st gear. Luckily I was only a few miles from home and limped into the driveway⌠replacing it with an updated L6-80 C-5⌠apparently this is a better option for replacement.
Thanks for the info - what brand of TC did you get for your L6-80/C5? If you could post the link, that would be awesome. Thx!
Did you ever find the conversion flex plate to allow for 6 bolts? Thanks!
My 6L90 TQ from a 2017 Silverado HD 6.0, lasted 75,000 miles. I hope your upgrade last longer than mine did.
Good to know that it failed that early. I am planning to swap to a billet converter around 200K miles which would be around 92K miles total. Sitting at 136K roughly right now but maybe I will change it earlier.
My TC in 2017 2500 with 80k grenaded the tranny dropped 5800 for new trans
Is it abnormal for a break In Period to occur after a transmission rebuild and an upgraded torque converter? I am having shudder and rough shifts that has gotten better, but still occurs 200 miles after the new tc.
The common problem with these transmission is the failure of the main pressure regulator valve in the pump, which drops the line pressure on these unit. In the early model the output shaft had a design where it also cleaned the fluids by catching debris with centrifugal force as you drove the vehicle around. Early unit use to go up to 200k miles with very little service. Then gm change the design of the out put shaft and more metal shaving (practical's) from the planetary sets started to float around in the fluid. So it is paramount to change the fluid on these units every 25 to 30k miles. Changing fluids on these units will help prolong the life of these tranny. Please do a complete transmission fluid service as you are installing a brand new Converter. Hope this helps and most likely you have done the oil change on it.
Frequent fluid and filter changes are a must for sure! I plan to service it every 30K miles as you suggested đ
Would a pump pressure regulator not throw a code and a dash light? I have the shudder but no codes whatsoever.
@@davidouradnik7925 No it does not set a code for a worn pressure regulator valve. Most of the time it will pick up a clutch pack is slipping code or solonied performance.
These models gm trucks have these common problem of torque converter getting shot. They have a design flaw for the torque converter. Our 2018 chevy silverado torque converter went out at 120k miles. We chose to rebuilt it. The transmission specialist shop replaced it with an aftermarket redesigned torque convertor and also installed a separate cooler just for the transmission to extend the life of the tranny because these gm models also have these problem of overheating tranny fluid. Hopefully this fixes the problem. Listen to Scotty Kilmer and get a Toyota. Our 2006 Toyota camry has 370k miles with the original engine and tranny.
They definitely don't make them like they used to. Do you know what tc the shop installed?
@@TheSundaeDrive Yea and I don't know which TC they installed.
Does the transmission retain the Lock Up after swapping the Torque converter? The clutch-like feeling that engages after 40mph to be able to drive at low RPMs without the Converter Slipping
Of course
Looking to add a stage 3 cam to my 2014 5.3l 1500 z71 (6l80e), I need help choosing the right stall for the stage 3 cam (219/231) (.630/.630)
Will this swap also include 4l80e in the 90's/ early 2000 obs silverados
My torque coverter failed right after you did this video and destroyed my transmission âšď¸. Cost me $5k for a reman. My truck is at 163k miles though.
Aww man, that stinks. You made it pretty far on the stock one atleast. Seems like it should almost be standard 100K mile maintenance item
... ZL1/CSTV.. could just got a regular truck 6l90 3 bolt torque convertor. granted I have a ZL1/CTSV 6l90e torque conveter from CDS in my truck.
Ask for high carbon clutches because even though that converter is a dual clutch itâs carbon fiber which frays (clogs the lines) use raybestos
This clutch configuration is like the 2015 f-250-150
I have a 2014 V6 silverado, is the converter also failing? I installed a drain plug in the tranny and dump it twice a year minimum
can you tell me if this 6l90 converter will work for a 2019 4.3 4x4 silverado
If you replace the torque converter, do you have to get the ecm and tcm reprogrammed?
So you didn't bother to replace the seal and o-ring?
Have seen the the stl010 Sure-Cool bypass just installed mine keeps your Trans cooler
Haven't looked into it yet. Planning to do the new GM TSB for the thermostat
my truck is at 180k still no failures knock on wood, 2014 5.3 420hp with tune and running e 85- just did a transmission fluid change and didn't see any metal on the magnet really. looked pretty clean compared to what iv seen. but looking into maybe changing the converter while everything is still working as it should
Well, is the 6L90 working? I'm in need of replacing mine, and I need the info on the converter you bought, please! Can you tell me which one you bought? Thanks!
when you got done do you have a converter lock-up issue? i did the swap and now at 40 mph rpms jump from 1000 1200 and back to 1000 every sec. put my truck converter back in and it was ok.
so i had the dealer parts warranty it and the 2nd on does the same.
What's the bolt pattern for the 6l80 converter
IDK how much the factory gm converter is, but you can find aftermarket billet cover stock stall single disc lock-up converters now for around $500. I went with a unit sold by trans star. Iirc these units are made by a company out of ohio and sold through trans star.
Good to know! I think this ran me around 400 or so but it's been awhile.
You mentioned there shouldn't be any tuning required. Is that true?
Can I put a 6l90 on a 2012 silverado 4x4 is it better and is it a direct fit? My 6l80 is burnt ima buy a new tranny but if a 6l90 fits I will get it please reply
Will this work in a 16 Silverado 5.3 4x4???
No problem with the 6l90e torque converter on a 6l80e???
I have a bullet converter Iâm installing into my 6L80. The bell housing is rubbing on initial install. Once itâs mounted to the engine will it then slide far enough away that the bell housing wonât rub?
Hey guys, Iâm new here.
I have a 2005 Chevy 2500HD and am swapping transmissions on it now. I have a 4L80E transmission and didnât know if I could put this on the 4L80 or what I could do to make it better?
Did your truck have any symptoms? My 6l80 is currently leaking heavily from the vent tube, wondering if this can be the cause
Mine did not. I changed it to be safe. I'm not sure if that could be a symptom. Honestly, if you are over 100K miles I would just change the torque converter to be safe
Is there a GM part number for the 6L90 torque converter? I have 2 I'm looking at one is gm10405 vs gm10403??? Thanks!!
It is listed in the description under the parts section :)
Can you post the link for the torque converter? Thank you!!!
My 2016 6l80 went bad at 110.000 the welds cause the converter to warp so i put a billet converter in it plus a rebuild its works like a champ now i have a fuel leak at top of the gas tank it needs a fuel pump and line
I have a 2015 Chevrolet Silverado V6 4.3 and I been told to replace the torque converter but I was told to get a heavy duty torque converter what do you recommend?
Can you give us a update on how the paint on the chassis has held up .Thanks.
I definitely plan to đđ just have to get around to pulling the bed off again
Appreciate all your video's and the care and details you take. Do you have any knowledge on the 8spd? There's many that have issues vibration/shudder and TQ replacement. My 17 HC with 6.2L has the 8spd, but I have yet to experience anything. Also I use Amsoil since bought new in 2017, from front to back.
Thanks for that feedback! Unfortunately I do not have experience with the 8 speed. I do know there are a lot of shuddering issues and various Service Bulletins out for them. I've heard that changing you something like Amsoil usually helps. If you dealer is able to detect the shudder they have a flush procedure they are supposed to do for free from what I understand. I think you probably have avoided the issues by swapping to Amsoil
Gm tech of 15 years, we just flush the 8 speeds with mobile 1 hplv now, works awesome, on the 6 speeds, it depends on the amount of metal in pan, small typical metal we flush with dex 6, large
Abnormal We replace converter, and will I lnspect pump and pump housing, also sometimes the tecm gets metal that busts through the screen and into valve body,. If ur 8 speed shutters â it can be pretty voilent, go up hill at steady speed of 35mph with trans well warmed up, if you have the shutter, youâll feel it.
I have a 17 Sierra with the 8 speed and the 6.2. Had the violent shudder at 30k and the dealer did a fluid swap and flush. 3 years and 27K more miles it came back but was worse with shudder, noise and slippage. The dealer replaced the torque converter this time, fluid swap and flush. They didnât see any metal in the pan, so they didnât do a full rebuild. So far so good this time. September of 2022.
Do you believe this will work in my 2017 6L80?
Im wandering after install how long it took before the front seal to start leaking. And that o-ring in the unput shaft for lock up. They are usually junk.
So far so good luckily!
How is that 6l90 torque converter holding up. I have a 2013 Silverado with 160,000 mi. When I shifted into gear and hold the brake I can feel the torque converter. I meant off the break and for 2 seconds it's still there but after that it's gone. I thought it was the brakes but I turned and put new brake pads. It's a very light Rumble in the brake pedal but I'm pretty sure it's the torque converter. The reason why is because I had a LS that the transmission was jacked up wrong and it needed a new torque converter. And it feels like the same Rumble you never forget. What's your thoughts
No issues with my 6l90 transmissions so far. I have about 22K miles on it. I do plant to change it out when I hit 200K miles (90K on the converter) to a billet just to be safe.
Can you provide part number of the 6L90 torque converter you used? Thereâs a lot of interchangeable parts Iâm seeing between 80 and 90
Iâve got a two-part question is there anything you can do to prolong your torque converter/transmissions lifecycle? Also, is there any upgraded tour converters that you can install instead of the AC Delco one?
I have a 2018 Chevy Silverado Z 71 4 x 4
Yes, a billet tc would be the way to go. And frequent filter and fluid change. I recommend every 30k miles as well as a cooler thermostat
Change the fluid more often if you tow a lot
What is the stock stall of the 6l80 vs 6l90 - you mention this is practically a bolt-on replacement - no tuned needed- is this 100% accurate and is the only difference between the 2 tc is the beefer internals?
The TC just went on my '15 chevy express 3500 van with 6L90 at 121K. Wish I knew about this problem so I could replace it before failure
That stinks đ definitely recommend going with a billet transmission for the rebuild.
I have a 2018 gmc sierra 1500 with a 8L90 and wanted to do a change out with a new torque converter. Who has the NEW torque converter and what is the part number if anyone knows ? I do not want to just put in the same converter that has the same failer problem. Thanks.
Thanks for the information! Got an 07 Yukon Denali at 181k. Transmission is acting up a bit and suspecting the torque converter is on the way out. Going to install a billet TC from Circle D and replace a rear main seal. Wish me luck!
Good idea! Best of luck with it!
did it work
@@brandon367011 Yeah, both worked great. The leak was primarily the rear main seal, but also a leak in the plenium cover. The new torque conver also workes great! The old converter was not holding well and rumors say that a high mileage TC could ruin a transmission by sending material into the transmission. I'm pretty happy with the results.
@@20tea good dead ! I have a 17 Silverado on 35 with only 51k miles and isnât my daily driver but I should change the TC anyway from a 6l80 to a 6l90 ?
I would recommend a bullet converter. They normally will last until around 100-120K unless you tow a lot. It could fail earlier but not typically
In the last 2 weeks, my 2014 GMC Sierra sle (131k miles) with the 5.3L started to shift in and out a bit randomly, also occasionally makes a rumble strip feeling at highway speeds when going up hills with just a bit of throttle applied. I just had the dealership do a transmission flush and it is better but not fixed. Dealership said it could just be the torque converter but recommended a full transmission replacement anyways at $5,200 and change. Iâm considering my options. Iâm handy and have tools, but more carpenter than mechanic. Do I try to save the $1,000 and drop the transmission and replace torque converter to see if it works before spending $5,200 on a replacement?
If the flush made it better in my opinion there is a good chance the transmission is ok and the torque converter may be starting to disintegrate and clog the lines. To me it's worth a shot because the torque converter will need to be replaced regardless. Is the transmission slipping at all? The sooner you replace it, the better chance you have of saving it if that is the issue. That is just my opinion tho as it is hard to know for sure without opening it up
I havenât noticed it slipping at all. How difficult is it to replace? Easier to pull the tranny out to get at it or the motor? I think the dealer was thinking that if replacing the torque converter, may as well switch the tranny too since it would be out.
Easier to pull the transmission for sure. If you are doing the labor I'd only do the transfer case. A good shop can probably do it in 6 hours or less I would imagine. I've never pulled the trans myself so not positive.
@Fishermanjuice22 do you mean the rps fluctuating a few hundred rpms up and down whe the torque converter is locking up?
The thing like rumble strips is the torque converter clutch starting to fail. It is random slippage of the clutch that shakes the torque converter. It is commonly referred to as torque converter shudder.
Does anyone have experience with a high pitch whining coming from transmission area? Happen in P,N,R,D. Some research points to transmission pump wearing but noise happens on and off, depending on the day. Fluid change? Filter change? Or complete rehaul of trans pump and TC?
Whining noise is usually fluid cavitation in the pump. By that point the pump is wasted
I am curious that since the 6l90 converter is heavier, more mass, does it affect revving quickness or milagage??
It would be nice to hear from people who have done this mod and not just speculation, Thanks!
Did you know any new infos ?
Old comment, but my dad's 2012 just got a new 6L90 after his transmission died at 187k. It mostly drives the same in terms of "quickness", but the transmission feels a lot heavier when it shifts which honestly is better than the sloppy feeling of the 6L80s. My dad likes it more than when it was stock.
dose 6L90 fit 4.3 3rd gen Silverado 6L80 is dog water my tranny was at 240 fml
Just got my truck back yesterday mine failed at 71000 miles luckily I was still a few days away from my warranty expiring.
You are lucky! I would pre-emptively change it before it happens again. Normally they last 80-120K from what I've seen. If you tow a low you'll probably be on the lower end of that range.
Always replace the o-ring on the splined shaft, you should also have the transmission tuned to not allow TCC clutch to slip so much. I use Hptuners and bluecat software. And dont ever buy a reman converter unless you want to do the job twice.
where can I get this part mind is a 2014 silverado with 6 speed 4l80 thanks awesome information đ
I linked to one on Amazon but might be sold out. I purchased through my local dealer.
Should replace the green turbine shaft seal also.
Wouldn't hurt!
What is the price of this 90 converter ?
I also flipped the pill in the thermostat
That definitely helps with the temps
Does anyone know if this issue is exclusive to the 14+ pickups or if the 2010-13 6l80e equipped pickups have similar problems?
Not sure but maybe someone else will weigh in
My 2011 Silverado had the torque converter go out and trash the trans at 105k. My 2017 Tahoe had the same issue at 75k. I drove the Silverado way harder than the Tahoe so... I'd say yes.
Where did you buy the Conversion Flex Plate?
I didn't. I used my stock flex plate.
6L90 will fit in my 2015 silverado . what other convertor can fit ?? please help
If you have 6l80 transmission yes.
Can you put link for the torque converter
What's the part number # for 6speed 2015 GMC Sierra 1500 5.3L 4x4.. please help
I have the 6l90 torque converter linked in the description 24242552: amzn.to/3oSVMuk
How is this torque converter holding up for you still??? Am wanting to swsp out the shitty torque converter in my 2015 silverado 6spd. And think this may be the one I want
8K miles on it so far with no issues!
As I sit at the dealer watching this video. 130k. Just started feeling some irregularities. Dealer is doing some diagnostics for me. The tech mentioned tc failures. Will know more shortly. Ive watched a few videos and they all seam to be well done. Feel like Iâll be watching more soon. đ¤Śđťââď¸
Best of luck with it!
@@TheSundaeDrive worst news. Tc failure, transmission failing. Got a quote. I think Iâm going to call and make arrangements tomorrow. Just a bit out of my capabilities. Enjoy watching your videos though.
@@two4twentysam sorry to hear that :( make sure if you plan to keep the truck you get a billet torque converter otherwise it will just fail again
Any part number on the flex plate conversion?
I'd like to know as well, my 2011 chev express with 6.6 duramax, I had initially thought it came with a Alison, but it is a 6l90e with the torque convertor fail and so the story goes, the trans was next, now I have purchased a 6l90 out of a 2014 pu problem is my og tc has 6 bolts but none line up, or so says the shop, so if anyone knows the part number would be mucho appreciated
Have you done a video on the thermal bypass to keep these things cooler ?
I will be. Not yet.
Check out precision transmission, they did a pretty good one.
Will do đđ
Instead of hoping that the 90 torque C holds up, might as well put a good after market converter like a circle D and be done and have piece of mind! Thx for the videos!
Great point! I actually spoke to them tho and they did not have any with a low stall like factory. they said going with 6L90 was best for my application
That is strange. They did have a low stall truck dual disk one in March of 2020.
what is the best torque converter for Yukon XL 2WD 2015 to buy?? the OEM or the aftermarket ones??? appreciate your feedback regards
Aftermarket for sure. Just need to find one that has a good stall rating for your application. I haven't looked into aftermarket options too much yet tho but I will when I start getting near 200K miles in a few years
I have a 2015 suburban what torque converter did you wind up going with? Thx
where did you get the 6l90 torque converter??
Local dealer
Hi will this 6l90e torque converter will fit Silverado 1500 2015 5.3L
If you have the 6l80e transmission it should
Would this work with a 2009 Silverado with the 6l80?
Most likely but probably should confirm with a transmission shop since it is so much earlier. Not sure if there have been updates
Gonna have to do my torque converter!!! Any issues with the 6l90 converter????
None so far for me! 20K miles on it
What stall speed should I use for my torque converter ? Complete stock 2015 Chevy Silverado z71
You should stay with the stock stall then most likely. Talk to the shop you are buying the torque converter from and they will be able to provide more insight. Circle d makes good torque converters from what I have heard.
@@TheSundaeDrive thank you
My first transmission failed in my 16â Denali at 32,000 miles and now at 58,000 finally did a service on the tranny and the torque converter is crap in the new replacement:
Good afternoon brother,excuse me; can l full they torque Converter with installed transmisiĂłn?
Not sure I follow the question?
My 2015 Silverado had this issue at 55k miles. It was still under warranty but the whole transmission had to be rebuilt. It got debris and wouldn't move once that debris clogged it up. If I let the truck sit for awhile then start it, it would move for a few minutes but then it would stop. All fixed under warranty though.
that stinks man - you were fortunate it occurred while under warranty. Can't believe it failed with such low mileage - most of the failures we have heard about were at 80K and above.
@@TheSundaeDrive i believe it was the torque converter at least. It's been a few years. I'd have to find the report from the dealer but I know it said they found debris that was clogging it up. The truck is at 85k now and I haven't had any issues!
It probably was
My 2015 is doing it, just turned 50k. What makes no sense to me is that I purposely had the truck tuned by Diablew to prevent (delay) any future transmission issues. Didnât really start doing it until after I tuned it and driving it on the interstate more instead of short back road trips. Iâm thinking of doing a flush/filter since itâs probably never had one done. But I have a feeling Iâm going to be doing a converter here soon. 𤨠tempted to go ahead and fork over the money to do a proper DOD delete with a small cam and a 6l90 converter since I like the stock stall for any future towing needs/keeping torque down low in the power band for my larger all terrain tires. Also thinking of putting an aux cooler and a deeper pan on it to help save the trans.
My thoughts exactly. Preventative maintenance is key with these trucks.
Whatâs the part number from GM for that spec converter
6L90 Torque Converter 24242552: amzn.to/3oSVMuk
Would that torque converter fit a 2017 silverado 1500 6 speed?
If it is the 6l80 it should
nice vid again when will your truck be back on the road'??!!
It's actually been back on the road. Have a coolant issue I'm trying to solve tho. We'll have an update soon.
how fast is 6l90 in auto ???...........how about 8l90 ???......thx..........just curious....
Canadian here so it's in kms but I got 280,000 out of mine but it needs done now !
That's a lot! I do plan to go billet before I hit 80K miles on this new tc. Just to be safe.
How has this held up so far? Looking to replace the TC in my truck as Iâm getting some noises
No issues at all. Billet is better option tho if you can find one you like.
@@TheSundaeDrive over twice the price for anything billet that Iâve seen. Any specific reason for going billet over the 6l90 like towing for example? Unless youâre aware of a billet close to the $400 mark
Be careful when you tighten the fill and drain plugs, they are tapered plugs and if you over tighten them you can crack the transfer case at the holes.... Lesson learned the hard way, don't make my mistake!!
Iâm at 290k miles and just now having issues hoping this fix the issues I have
I changed my torque converter and it was good for a while but is havingbthe same lag and shakey symptoms. The rpm jumps while braking always. Do you thinknthe whole transmission is bad or just bad torque converter
Did you ever figure out what the issue was?
my 6l90 converter blew up at 102000 miles went with the billet converter with the rebuild
Good to know! I plan to swap it out around 200K for a billet. Which one did you go with?
I just got a stage 1 6l80e with the 24242552 torque converter from a cts-v will it bolt on to the flex plate with no issues since mine has 3 holes & converter has 6 and how is the truck doing with torque converter upgrade
What transmission does your truck currently have? The 6L90 torque converter is working great! No issues.
@@TheSundaeDrive its gonna have a stage 1 performance 6l80 had a single disc 2800-3200 stall converter but had to drive 5 hours cause torque converter was bad and they gave me that converter from a cts-v so in mids of august ill be installing it also truck has bolt ons gears trutrac hptuners tune so if yours is doing well im sure mine is to
@@TheSundaeDrive hey just an update my 2013 already has its stage 1 6l80 6l90 torque converter it is great shifts are really smooth feels like a whole different vehicle
Thanks for the update!
