Glad I watched this as I go through my first LS swap!
That's a great advise that could save redoing the work, & more money. Thank you.
Just taken out my auto box. The flex plate had a crack all the way around. Now I know why. It has been out before so I guess it wasn't lubed properly.
New Plate is on order so I will follow your instructions.
Good Job, thank you!!! Didn't know that.
The hub... Yeah, experienced that first hand: it had been assembled [25 years earlier?] dry. Tried to pull the engine and it started dragging out the torque converter with it, which just didnt work because of engine bay clearances. A large crowbar saved the day: my little 2 footer was going nowhere. Reassembled using some SP400 [which hardens to a wax like consistency in about a day/less likely to sling off] after cleaning it all up with a wire wheel.
Good basic stuff - a straight up video. Little things always add up over time.
Where can I buy that sp400?
@@budthechud3408 Pretty much any place that sells crc products. I have a grainger near me which is a little expensive sometimes for some things, but they turnaround orders fast.
Great information, my car brake 3 times the flex metal plate I don't know what happened scared I think to swap to standar..... Bmw e46
thanks for the great help how to grease the torque converter to the crankshaft and the other side with a small dos of transmission fluid benny
Good tips!
Thanks for the tips man
In your video (and others) it's noted you have to rotate the converter until you feel 3 clicks or clunks as you push the converter in. I ruined the first one I installed in a'75 Dodge W100, 360 V8, following that sequence. After I bolted it all up it didn't work so well. I called the transmission shop and they told me on that particular transmission, you had to get 5 clunks to engage everything! I ended up paying for another one, so just wanted DIY guys to be aware that it may take more 'clunks' to be fully seated. If you have to pull the case together with bolts--It's NOT seated. My bad!
thanks you saved my future torque converter . i will do 'clunk' as the most times i can do
@@hongmihnhahn7081 Glad my comment helped someone else--experience is the best teacher. Sherm
You don't count clunks you spin it back ad forth as many times as it takes to get it all the way in if you can see behind it it's not all the way in and if it touched the flywheel before the trans bolts are tite it's not all the way in you should have to actually pull it towards the flywheel a tiny bit after trans is bolted tite to block.
Another good way to get it seated--the main point is that it's not seated if the case doesn't slide completely together without forceful effort--it should just "clunk" into place. Thanks for the added advice. Sherm
@@georgealmeida7382 Exactly,on most trannys your supposed to run a straight edge over the front of the bellhousing and if the converter hub is hitting the straight edge is not fully seated but yeah clunks are just a reference,you have to make sure its fully seated,kinda like saying "well i pressed the trigger and the gun didn't fire so it must not be loaded,you have to physically check before pulling the trigger ha ha ha ha
Glad I watched this. I was going to use motor assembly lube on the main seal shaft for installation. I've done it for years - thinking a small amount is harmless to the transmission. I guess I've just been very lucky.
Yes, you have been lucky.
@@jgtransmissions3283 Mine is leaking from main seal because it was probably greased, anyway of making it seal without pulling the trans.
@@ClarkeMotorsOC I don't know if it would work, but LUCAS transmission additive is very thick, it may stop a small leak.
Your saying on the side that goes to flex plate put grease and just transmission fluid on trans side right? Didn't put grease and did try to push and turn it to sort of lock it in place. Could the not putting grease cause the wheels not to spin.
👍😎👌Excellent video. Are the 4l60e, 4l65e, and 4l70 transmissions interchangeable? I'm looking to do a direct swap for my 4l65e I have in my Hummer H2 SUT.
Hi, one question what kind of grease you need in the shaft side you mensioned seize, it can be a little bit of PERMATEX anti Seize grease ? Thanks
Here i am watching this video from Botswana at 12am , hoping I'd find someone saying its "perfectly fine not to grease the dang pilot" cause woww😭😭😂😂😭 ..
Thanks for the heads up💪🏼
Great tips
Just put new trans and verter in and didn't seat the converter all the way and ran it for about 5 minutes did I ruin the pump or no?
5r55e transmission, can you install the torque converter seal to deep into the transmission.
I have a 2003 f150 automatic 2wd 4r70W and when parked or in low gear I feel what feels like the t/c wobbling a bit, shuddering? but there is no shifting issues or slipping issues. Around 45mpg it shakes a bid. I feel it shaking more in part or in 1st gear. What could this be? I'm thinking just a bad torque converter.
On the few viDOz Iv seen on those tOrq converters sliding into transmissions, the only contact I Cn with the back of torque converter is the splines go into that tube on back of it, but nuthing touched outside of that tube, sO I would've guessed transmission oil the splines & that's it. Is that wrong?🧐
Took a 4.41998 5.4 and putting in a 2003 f150 5.4 bolted up all plugins different in the transmission and now like the torq is locked up like flywheels and torque turning togther the bolt is so close but I don't know what's the deal pur wrench on motor crank and cant turn it at all
Is there a specific way to install my torque converter on my C4. It has four threads that go through the flex plate. Held on by four nuts.
should the converter .... a c/6 ford .....be filled with fluid before installation ?
Good tips Thanks !
Liked/Subscribed !
Thanks for the subscribe!
@@jgtransmissions3283 I had a question could you use anti-seize instead of grease?
Good info.
Getting ready to replace the front shaft, torque converter seal on my 96 Camry V6, what brand of seal do you recommend I get, it's the A 541 E transmission, any advice would be appreciated
Recently got an fti 3600 9.5 billet converter for a 4l60e an it keeps leaking transmission fluid any suggestions
Much obliged.
And pressure test converter to make sure welds are good.
What if I did not add transmission fluid to my toque converter??
It appears that the torque converter in your video is leaking. Is that normal? The reason I'm asking is because I had to remove the torque converter with the engine (engine was locked up) and I noticed that the TC leaks fluid when held transmission side down. I'm curious as to whether that's normal or if the TC is damaged. Thanks!
What kinda grease? Sump pump?
yhank you very moch
Forgot to mention a very good note as well figured I'd share and that's to make sure the torque converter is full of atf otherwise you will have issues
Doesn’t it get filled via the shaft while vehicle is running?
It was suggested to me to just add a quart of trans fluid via the open snub that indexes onto the pump shaft before installing, and then the torque converter will fill the rest of the way quickly once everything is installed and the engine is running.
Wat type of torque converter is this
Good morning. I love your video! I have rebuilt my TH350 and have some experience with installing transmissions. I have a question about bolting the torque converter to the flexplate.... Since the torque converter sags ever so slightly from its own weight when resting in the transmission, prior to bolting to the flexplate,, should you lift it up ever so slightly (take the weight off) as you tighten the first torque converter to flexplate bolt? Or just pull it forward and bolt up without lifting on it?
I used a transmission jack--(they rent them at O'Riellys) and was able to adjust the transmission at the right height and tilt angle that it rolled right in place with no binding, installed the bolts and snugged them up tight, then removed the jack and torqued the nuts in a cris-cross pattern--much as you would when mounting a tire on your car.
Whats that torque converter go to? Transmission type. 350. 400. 700r4 4l60????
How about pouring a quart of ATF in the Converter
This is true about the lube on the torque converter I watched a you tube program they said to lube it so I did and now it leaks.....
What method would you recommend for changing transmission front pump seal if no seal puller? I saw on youtube a guy used a screw on the top end of the seal to work it out. I know it sounds scary but the way he did it may it look safe and easy. ??? Thanks in advance
I used a seal puller then drilled a small hole into the seal to a drywall screw and yanked it out.
Very thorough thank you. I have a 14 Ram 2500 with the Cummins and 68RFE. Since it was brand new it has always clunked in the driveline at low speed when letting off the throttle or getting back on it. If I do a transmission relearn on it, it goes away, but only for about 100 miles then it comes back. Any thoughts?
That sounds more like a bad universal joint to me?
@@shermorton7170 I thought so too but they are all good, only 48k on the truck now. If I do a transmission relearn it goes away then comes back.
My jeep aw4 is losing fluid at hiway speed. Only on long grades uphill. I think its either the converter or the gasket or seal on the pump. Around town delivering pizza and flat hiway no loss of fluid. Uphill it dumps and drips on exhaust and leaves smokescreen like a ww2 Fletcher class Destroyer.
Installed spare trans and it works fine. Having voltage issue to tcu but all works. Not one leak. And added new t case. Got rid of my 1988 t case.
And added hack n tap sye
The input shaft the torc converter goes on has a o ring into the spline, my O ring was in bad shape.....can I use a normal o ring? I purchased a new torrc converter and installed the new seal....but I think the leak was due to the worn input shaft o ring.
Your job is probably done and over with by now but I'd recommend a/c o-rings to stand up to oil pressure
I put a new pump seal on a AW71 (using a AW70 converter) then installed it in my Volvo. I used a few drops of Lucas ATF additive oh the hub of the converter/seal surface. The trans worked great for 25 miles then began to leak from the converter to pump area. I can't see that the Lucas (which is the viscosity of STP) could cause this. Also the car didn't leak for 45 minutes running on the lift... Any ideas?
I haven't worked on a Volvo or any other foreign car--they are a different animal!
Awesome
Also I believe you need add one quart of mission fluid inside the converter
What if I did not add transmission fluid to my toque converter??
should the outside surface of the torque converter hub that goes into the tranny be really smooth?
mine has a layer of surface rust on some spots from sitting under a carport. also some light pitting.
should i just use fine sand paper to sand down the parts with the surface rust?
will the very small pitting affect anything?
Spray brake cleaner on a shop towel and see if you can wipe it away, if not then I recommend using scotch Brite or a really fine steel wool, with a little brake cleaner. Don't spray directly on the part, and make sure to wipe it dry (I also wipe a little trans fluid on it after, then wipe that off to be sure it takes any residue with it)
Also if using steel wool, remember to use very light pressure
Sir good day! Gonna ask you something..can do the tourque converter fluid and the transmission fluid share the same fluid? I mean can a fluid from the transmission can go to the torque converter and so forth?.please reply sir..tnx
Yes it is the same fluid.the trans moves it around as needed.
Another installation question. I just put in a new torque converter in a 42RLE. The transmission mounted fine and the converter bolted to the flex plate fine. However once the transmission bolts are tightened to the housing you can’t spin the flex plate. It’s locked up. Spins fine with 1/8 to 1/4 inch of space between trans and engine housing.
Do you have any ideas?
Did u ever figure this out I’m about to replace mine
@@AFAnthony I did. The torque converter seats inside the transmission. You have to spin the converter and it will notch inside 3 times before it’s fully seated. If you only get it in say 2 times it will be sticking out to much and it binds once you bolt it up.
When installing it just make sure the converter is fully sunk in behind the edge of the housing. It was my mistake.
@@patriotfox7192 i put the torque convertor in heard 2 clunks a small one and a big one maybe i got two in one it was pretty well in the bellhousing i bolted it up no issues but the the flexplate is always hard to move anyways once all bolts are in i can spin it but it requires a bit force is that normal i just dont want to start it and then go boom (thanks for the response btw)
@@AFAnthony yeah the flex plate should turn with resistance because it’s moving the pistons. just like spinning the front main pulley. It won’t spin free but the same resistance as when you unbolted it. It would be almost impossible to spin if the torque converter wasn’t seated all the way. Like really hard to spin.

CANT TURN IT
Does the converter need fluid in it before installing or can be installed dry?
Some people install them dry and say the pump will fill it up in seconds and others say fill it up before installing it, personally i would put some fluid in the converter before running it.
That’s what the transmission shop told me.
The part that goes into the crank is called the pilot. The hub that goes into the pump should be lubed with Vaseline or trans jel
WHY WOULD A TORQUE CONVERTER LOCK UP
Just use some ATF?
Thank you , I have not done an automatic transmission yet, so I am collecting info. just in case. If you wait until you are ready to do a job, then to get info. your'e more likely to get in a hurry and do the wrong thing. Working on your own vehicle is like the adage A LAWYER WHO REPRESENTS HIMSELF IN COURT HAS A FOOL FOR A CLIENT. ; when you work on your own vehicle you are emotionally attached to it, so you may become impatient because it is your daily ride and you need it.
I removed my 4L60E and the torque converter stayed in the flex plate. Everyone I see installs their trans with the torque converter in the transmission.
Did I mess up by leaving it on the flex plate when removing and reinstalling my 4L60E?
Yeaaa lolol
Correct spacing of the torque converter is critical. You can damage the transmission pump or even the thrust bearing in the engine if you don't space it correctly.
@@melsharples7921 but if that’s how it was spaced installed from the factory. Bolting it back on shouldn’t change that spacing. Am I wrong? Same trans, came converter and fly wheel.
A torc converter should be installed into the transmission....when you turn the torc converter you have to hear three snaps to seat it....if it’s on the engine you can screw many things up....the torc converter needle bearings or the in put shaft splines.
Does that also cause it to not lock 🔒 up correctly it feels like putting the Grease will help it slip correctly to gear ⚙️
😢 mine keeps locking up
