One thing I found out is, be sure you get the same year trans as the pcm/motor. My motor and pcm is 2015, the trans I found out is a 2013 and has a different OS, so I need the TCM flashed with proper OS.

Your right Vannatta20, these can be a real cool setup( definitely hoping for this!) or a real nightmare.
