06 PCM in a 05 GTP?

[Mobile Chassis Dyno]

I am going to guess the answer is no being the 06 is CAN BUS. However, a customer asked me about putting a 05 PCM in his 06 Grand Prix so he could tune. I assume he would have to do a complete wiring harness swap to do this?

If I'm not mistaken, the trans is controlled by a seperate computer in 06 as well. Don't quote me on that. You can ask over at clubgp.com and get a quicker answer I'd imagine
