    Not sure what I'm missing but my car will shift fine foot braking with a shifnoid and I can use my use my transbrake to back up or rev it up in low gear and it's fine until it activates the 2 step. As soon as it activates the 2 step the car shifts into high gear? Any help or where to start looking is greatly appreciated
