A few 4L80E Questions
Im just going through my 80E and putting my Trinity Trans brake in and had a few questions:
What is a good clearance for the clutch packs?
I want to convert the direct drive to a 6 pack instead of a 5 pack, does anybody have a part number or what thickness of clutches and steels i need to achive this? Any other good tips or tricks would be appreciated as well.
Thanks

If you use the molded piston in the directs, 6 4L80 high energy frictions, and 6 4L80 forward (thin) steels should get you close to your desired clearance. Don't forget to remove the center seal in the drum.
For the intermediates, use 4 4L80 high energy frictions, and a combination of 4L80 and th400 steels. I don't remember off the top of my head how many of each. I would get 3 of each, so you'll have enough for the correct combination.
You can set the forward drum up a little tighter if desired, for it is applied all of the time. Being that it is obviously a race transmission, get rid of the wave plate in that drum as well. Use a combination of fwd and direct steels to get your desired clearance. 5 or 6 frictions, either one, will be fine.
Put a th350 pump bearing in the bottom of the case and set the end play with th350 pump shims on the tight side. .005 is what I like to shoot for.
Let me know if you have any other detailed questions about the build.
