Project 4L60E part 2 lesson 5

This video is about the assembly of the input drum. It's one of my longest, but there was a lot of material to cover. It's also one of the most difficult areas of the transmission to put together correctly with the right clearances. I hope it helps. Watch my videos in order at www.transmissionbench.com.

[@alonsomeza6913]

I am grateful to this man I put together my first 4l60e and he saved my pocket of 1,800 dlls that they charged me to repair it. I think there is no one on KZbin to explain this, it is number 1 on the internet if I could give it a million thumbs up I would do it thank bro 👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼🤜🏼🤛🏼

took me awhile to find this comment! The gum was in part 1 lesson 1 and then disappeared only to return on this vid, part 2, lesson 5. I'm not trying to do a rebuild - only just want to learn and listen to the gum chewing!! It drives some people crazy I guess - I thought it was a lozenge at first for dry mouth. Now I understand it's just all about street cred and "verga" as the Mexicans say....

Thanks for your comment about the Lancia. I would like to have some more time to do more with it. Ain't that always the case!

[@deankay4434]

Just a couple of comments to add as we go into 2020. First, it is important to leak-check the orifaced cup plug in the front of the input housing & shaft assembly. Re-stake or replace after cleaning and fails to seal for the 3rd - 4th apply piston. Secondly, improved “Blue” rubber compounds that withstands the thousands of heat cycles and wear from movement sold in sets of 3 of steel molded pistons. These will last way longer, unless you need repeat work every 8 years! I’ve known many techs who skip steps and don’t even know the Oring that goes onto the internal nose of the input forward housing shaft assembly before the 3rd - 4th clutch piston is installed. ASE Master Tech / 1978 / Retired Other, nice series of sectioned lessons.

[@deankay4434]

For those building a 82 - 93, TH700r4 - 4L60, using the “Blue” rubber type molded steel pistons, the spring retainer shown at 10:21 is required. It is ACDelco p/n 24206085. It is narrow and has a steel end plates and works with the same clip. This “Blue” rubber compound is 4-5 times more resistant to heat, retains its shape way better and allows for use of the 0.50” boost valve that increases line pressure and can deform the aluminum pistons. Checking for bent or deformed aluminum pistons is in the GM service manual. Low & reverse is the same but by design is heavier to start with. ASE Master Tech since 1978

[@Levi-jj4vq]

How do you leak check the cup plug?

[@deankay4434]

Levi, That a cool name! It is normal to add Solvent or mineral spirits 2 part to 1 part ATF. Using a hypo or straw with finger on end, fill the ball cap almost full. Take a lunch then check under it. Should be dry. Remember, 2 check balls in capsules, one at center rear and other over servo’s. High wear on high mileage cases and rarely checked. GM’s service manual says to use a #4 easy-out, I use a 3/8 fine tap. (Test for fit on size, but use fine) screw in until it grabs & turns. Place a flat plate on VB surface, grab with vise grips, turn, push down on handles if you place a flat fulcrum for pivot 1” back and it should pop out. They say to measure top for depth but it bottoms out with 3/8” drift. Cheap insurance for $6. Best to change, up to you but stay safe and wear a glove to watch fingers. Hope this helps! (Tip) hit video gear in upper right when at regular screen. Change speed to something faster. See something, slow down to normal the re-play. The easy-out trick is in the video I think. He is an “STG” GM instructor. Have a good one! ASE Master Retired.

[@mohammadazemi1609]

Appreciate for good explanation

[@MidnightMechanic]

I've seen plenty of transmission performance companies that like to install 9 clutches in a pack and can go as far up to 15 stacked! Do they simply use thinner clutch frictions and steels to achieve this, or do the bearings and washers have to be modified as well?

[@joelove450]

how much wear is acceptable on both journals on the shaft? I feel a very light step but I don't know if its really bad or not.

[@chrisdub6363]

What if the input housing has a few scuff marks around the top rounded edge of the housing (About 1/2 inch below the top where the splines are on the drum). The scuff looks like it is from where the reverse input drum sits on top of the input housing. Could the scuffs on the input housing be caused from that? Or maybe from 3-4 packs being burnt out, hence why my truck only had 1st, 2nd and reverse? Once my truck shifted to 3rd it was like I had pushed in the clutch but on a automatic transmission.

Hey I have a 04 gmc sierra with this trans and a new process 246 behind it. Do you know if transmission fluid is supposed to come out around the output shaft on the transmission in between the transfer case. I have my transfer case out and just rebuilt it and noticed with the engine running fluid squirts out around the output shaft on the transmission. is this normal our do I have a seal leaking. Thanks in advanced for any advice.

[@transmissionbench7842]

Hi Tyler. This is normal. The adapter housing will have fluid from the transmission in it. If you look, you'll notice that the splined input shaft of the transfer case has a seal around it to keep the two areas separate. Jimmy

Wish your videos would have been around when I rebuilt my 4L60E out of my 93 truck. But I haven't had any issues. I just ended up replacing the input drum with a hardened 300mm shaft that hopefully won't sheer at 600hp. And I replaced and the clutches and frictions. I've learned quite a bit from your videos if I ever end up having to rebuild it again. Is it ok to use a 13 vane pump on a 10 vane transmission? I'm just wondering because I put one on mine. Haven't had any problems just wondering. Also using a hardened welded sunshell and 5 pinion planetaries out of a 4l65E.
