i'm looking for info on an Allison 7400 I get a p0743 trouble code, and no reverse. I have replaced solenoid f, and still wont fix it I what causes po743 to set, and why does the tcc inhibit reverse. if the tcm is disconnected reverse works fine as does forward just locked in 2nd for forward movement.
