    That would help. It needs that sensor input to determine when the input and output shafts match in order to shift.

    Unplug the sensor and try it. If it doesn't work then. Keep it unplugged get a paper clip make a "U" shape out of it and stick it into the sensor plug.

    This fixed my shifter problem in my 07 Columbia smart shift(kept blowing fuse)
    Low coolant sensor
    I replace fuses with paper clips hahaha.

    But like G, Anthony said I'm not saying it's going to work it's a suggestion lol
