Abstract

A shift lock for an automatic vehicle transmission comprises a plunger 22 which is controlled by a solenoid 24 and cooperates with recesses in the base of a shift lever to perform both shiftlock and keylock functions. The plunger is spring-biassed to a central position in which it can engage in a recess at the Park position of the lever to lock this in Park when the ignition key has not been inserted and turned to a first position with the engine not running. This operation of the ignition key retracts the plunger to allow free movement of the lever. When the engine has been started the plunger is fully extended to engage the recess at the Neutral position and retraction of the plunger requires the vehicle brakes to be operated to allow gear selection. After movement of the lever to any forward drive position the power to the solenoid is cut to avoid heat build up therein. In the event of a power failure a ramp will allow lever to move from Neutral to Park, the plunger 22 being in its central position.
