Quote: Any chance this GM PCM can be tricked into controlling a Mopar OD trans?

I assume you are talking about lockup and shifting OD ?
I was wondering if it could control an RE trans as in 1 2 3 OD and lock up.

The only shifts that are controlled by the computer are OD and lockup. 1-2-3 are not really electric controlled, the E is for the electronic governor.
I just looked into this, and I don't believe the GM PCM can control the governor on 4xREs.
"Duty cycle on the Pressure Control solenoid is inversely proportional to the throttle angle (as throttle angle increases, duty is decreased) At idle (minimum throttle), the duty is at max (60%). At WOT (wide open throttle), the duty is at min (0% or off). Note that the PC solenoid takes the place of the Throttle Valve cable on earlier transmissions. "
I think it could technically control the RE's governor pressure solenoid, but the GM PCM doesn't have a (stock) way to read the governor pressure and adjust the output PWM accordingly. I don't know how much flexibility their tuner software has to add inputs and do software filtering and custom control of outputs. So, I think it's unlikely it would work.
Guess I'll continue my project to make an RE controller
If you ever find yourself in a fair fight, your tactics suck.
