It would appear I am trying to do (once again) the impossible....I've done some initial searching all over the internet, and I have found numerous threads (from numerous forums) with people going FROM a 6l80e to 4l60e/4l80e. I've found numerous threads on the methods, and even a piece of hardware that lets you go from the 58x to 24x crank setup...
However,I want to go the other direction.. I want to build an auto-crosser out of an '03 Silverado RCSB truck, the truck will have AWD and R-comps so it is not going to have traction issues, for this reason the 6L80e is very attractive to me (that, and I already own the Trans and AWD T-case). I am not able to find exactly what I am looking for to complete the trans install.
So onto my dilemma:
Is anyone aware of what exactly would be required to allow the use of the '03 24x PCM with the 6l80e transmission. I know the newer stuff has its own controller, but I believe they both still talk to each other.
Any help in advance is greatly appreciated.
