4L80E swap questions

[2005SnowKon]

was thinking about doing a 4L80E transmission swap in my 2005 yukon.. was wondering if there was anything special i needed to do? Vehicle has been reflashed with EFI live so i probably need it retuned after that... What else would i need

Welcome to the club. I've been eyeing this mod for a while but I just haven't pulled the trigger. Check out performancetrucks . net. They have a few writeups on 60e to 80e swaps in 4wd and 2wd trucks.
