I have heard there is a way to mess with the wiring and shift solenoids in the transmission to lock the car into a specific gear and keep it from down shifting. Like if you wanted to run 2nd gear and only second gear and the only way to get it into 1st is to manually put it there. Is this true? I have searched and found nothing. It is a 3 speed in a 1994 4 door Cavalier with a 2.2...
