Hi I'm new to the forum, I have a 2002 monte carlo with a 3400. I have a supercharged 3800, 4t65e-hd transmission, engine harness, and pcm out of 2005 gtp comp g that I am putting in the monte. My question is would the 2005 pcm communicate with my bcm right, or it there anyway to get a 2002 pcm to run that transmission?
