Hey guys, I've done a million searches.
Nothing conclusive
I'm working on this 2007 Silverado 6.0, originally had a 4l60 and now it has the 4l80
I tried the segment swap feature, but I know it wont work, ECM and TCM are separate.
I need the operating system of a 4L80 to write entire into the current TCM. No luck on the tune repository or on the search
Does anyone have insight on how this should be done???
I heard that you would have to commit to a set of credits for a vehicle with a 4L80 TCM, like the 08 chevy express 4.8. ? is this true??? I would like to get re assured before I burn 2 more credits.
Thanks guys
