Hey Dave and Bill,
I got a built tranny for a 99 GTP (with 300m input shaft, 7/8ths chain, etc.) and the car rotted out to the point where I scrapped it, well I bought an 04 GT (L26 not L32 and NO TAPSHIFT) and was wondering what I have to change wiring wise to make it work in this car before I put it in. I have a spare transmission harness from a 99 that I can change the pins around on if I need to then put that in my 99 trans that's sitting on the table. I also noticed that the 04 doesnt have the plastic box on top for the BCM&PCM to know what gear you're in, that's intresting.
