T56 to 4L60E swap

What is needed to complete the swap? A friend of mine took out his T56 and has a built 4L60E that he wants to install. Our main questions are: 1)will the PCM need to be changed out for one out of an auto car? 2)Will the wiring harness need to be changed out as well?

The computer won't need to be physically swapped. Use HP Tuners or EFI Live to make the necessary changes to the PCM.

You will also need the auto wireharness i got mine from lsx tune. I had hp tune and my dyno guy did the program. I think there is a sticky telling everything you need and some tips if doing it yourself.

You can use the stock PCM, but it'll have to be reflashed
