The chev in that P38 is a Tune Port Injected motor - much simpler electrics than an LS series chev! My view without being an electronics guru would be this:
Microtec or similar ECU on the engine, set up to chat with the transmission ECU (that's pretty simple to do), and BeCM. The last bit would be where the dramas are!
Nonetheless it's been done!
