zf transmission no engagement

[Jeff Miller]

The first thing to try is the TPS (Throttle Position Sensor). It is a
rheostat/sensor connected to a throttle cable, mounted to the outside-
rear (rear of coach) of the battery box. If the sensor is not returning
to the idle position (jammed, broken return spring, cable came loose,
etc.) the transmission will think the throttle is wide-open and not
shift into gear.
