If you want to be able to use all 6 bellhousing bolts, you need a 2000-newer 7 bolt case 4L80E. Otherwise any year core will work.
My personal opinion is to avoid the TransGo kit if doing a rebuild. It's a decent kit if you are using it as a temporary setup to use a wrecking yard trans.
The multi-layer separator plate can cause issues and if you use the TransGo kit, don't use the pressure relief portion.
I designed a valve body kit for the big power applications, and in lower powered applications (750 HP less) any knowledgeable builder should be able to setup a 4L80E to work well without a valve body kit.

The pressure relief can cause all kinds of problems. Not very high quality parts, in my opinion. (That's the nice version of what I think of them...)
The '80E is pretty easy to setup to take some decent power with just careful setup, pressure and orifice sizing.

Its a 80k mile 93 model trans and i want some kind of shiftkit in it..the motor doesnt make that much power but the truck is kinda heavy and i want something i can depend on...i have two different flexplates(flat one and the one with the spacer)..but i dont know if a 4l60e flexplate will work with a 4l80e converter?
