I've searched....

Is there a plug n play harness available for going T56 to 4L60E?

Want a smooth transition in a swap.

i dont know a whole lot about it. but i do know that the interior harness is a little different, and you obviously have to re-tune the computer. other then that there isnt much. im sure someone will chime in that has experienced this first hand though. good luck

I did this swap. Its not too bad wiring wise. Just get an auto engine harness and follow the write up that they have in one of the stickies. I do remember seeing a harness where you could adapt your M6 engine harness for the auto but it looked like it was a bit involved.
