a friend of mine gave me an 02 4l80e trans mission. My 4l60e is giving out and want to either have it built or install the 4l80e. Is there a harness for the swap and will it be compatible with my pcm etc? dont want my dash to look like a chrismas tree? Already did a search an nothin

 

red heartbeat has put a 4l80e in a gmt900 truck. do a search for his posts and you will see his write up. i will be doing it some time shortly in my truck.
