4l80 questions
I picked up a 08 4l80 core a few months back for my chevelle. I plan to put it behind a 03 5.3 and have read that the 08 trans will not work correctly with the 03 pcm. Is this true? If so when I have the trans rebuilt can it be changed to work with the older pcm or do I need to be looking for a different year trans?
ThanksBrad Shepard
