Just need the year of the transmission, the proper pigtails for that transmission and the wiring schematic for transmission to computer. You could probably just talk to PSI and they could make you one.

I kind did the same thing on my LS6/T56 C10 swap. Went to a 4L60E. I took the easy way out and sent the harness back to Howell and they reworked it to work with the 4L60E. They also reworked the ECM to work with the 4L60E. Went great. I bet PSI could do the same.
