ABSTRACT:
In an automatic transmission, a sensor switch is provided to monitor movement of the gearshift lever from the park position. If the gearshift lever is moved out of the park position when the ignition is off and/or the brake is not activated, the switch responds to such conditions by exciting a locking device which inhibits further movement of the gearshift lever from the park position. The locking device requires current only when the gearshift lever is being moved from the park position.
