It's the same valve body, only the parking rod changes. I have wired them all the way back before, and street drove that way for years. Doing so makes for high shift points in drive, as the trans "thinks" you have the pedal to the floor whether you do or not. I got away with it as the car had 4.86 gears, so it would still shift to high gear below 50 mph. It would be really annoying with 2.76's ;)
