I found someone who has an 04 GTO with the 4L60E trans and I have a 99 T/A with the T-56. Does anyone know what exactly i'm going to have to give him to complete his swap and what he would need to give me for my complete swap?

You are in the wrong forum but you both are going to need new PCM's, and wiring harness for the swap, its not just as easy as swapping equipment and re-flashing your PCM.

No PCM required, you can use yours. Same goes for the wiring harness. I made my A4 harness work with my T56, I swapped mine out about 2 years ago. All you will need is to get some A4 pedals with all the sensors, usually you can just swap yours for somebody wanting to swap a t56 into their A4.

Then you just hook up your neutral safety switch and you will be good to go, after a tune of course.

With the power you are making I wouldn't put a 4L60E tranny in that car anyway. If this is a daily driver I would look to get a 4L80E or if you don't mind not having OD or a lock up converter then you could swap in a manual valve body th350-th400 . All three of the above transmissions are 100% better than any 4L60E you can put into your car. Just my .02 cents and something to think about.

I ran a FMVB 4L60. It was stressed out under the 880rwhp it was being fed from a 300 shot.
