4L80E Clutch Packs and Upgrade Parts I bought a used 99 4L80E with 72K miles. I pulled it apart and the inside looks great, but I figure I should beefen it up and replace all of the seals while it's apart. I'm going to put a Transgo HD-2 kit is as well. I'm looking for it to hold 700-800rwhp, will not be locking at WOT, it will be 100% street driven daily driver. It's going into a turbo 01 Silverado extended cab, probably weights in around 5000lb.
What clutch packs do you recommend? The packs I took out look to be in good shape, but I might as well replace them all. I few options I've seen are Alto red eagle, Raybestos stage 1 and Z-pack, and Borg Warner high energy. The Alto packs are easy to find, but the others are hard to find.
And I keep hearing about a 34 or 36 element sprag as being a good upgrade. I'm not sure what mine has or what the sprag even is.
What other parts should I look into to beefen it up?
Thanks.
