I've been searching for an hour and I can't find this anywhere on here so I gotta ask, what does it take to swap a 4l80e into a 5.3 Z71 with a push button auto 4x4 and keep the push button auto 4x4 with no issues?

 

Check out KYsilverado 's thread on this exact swap. It helped me a bunch.

Thanks for the help guys

 

Looks like I can get most of the swap kit from ebay if I can figure out if I have a early or late style gear selector switch in my 05 though I'd rather convert the T case input than the trans output. Looks like other than that, I need everything from crank to tailhousing from a 6.0 2500 truck though I'm certain they don't make a SCSB 3/4 or 1 ton for a donor rear driveshaft.... if that's actually necessary that is

 

If you get stuck, pm me your number and i can help ya, im not the best typer LOL

 

Ok will do. It will be a while before I begin this project since I have a F body 6 speed swap going on at the moment but I'll keep keep you in mind. I'm trying to talk TCI into building me a 6X 4X4 tranny
