i just rebuilt my c4 and put it back in with new vac mod and now it will not shift
i can manualy shift from first to second but it will do nothing in drive but stay in first gear
i had help from my friend who has rebuilt these tranys from ford and he thinks that there is trash in the valve body and we need to break it back down
any other ideas that i can try
thanks
sean

Make sure the valve behind the modulator isn't backwards and the pin is there.
