ABSTRACT:
A shift module assembly for controlling the movement of a vehicle transmission out of a park condition responsive to a condition of the ignition system of the vehicle and responsive to a position of the vehicle brake pedal includes a moveable swing arm adapted to selectively control the condition of the vehicle transmission. The swing arm is in a park position when the vehicle transmission is in the park condition. The swing arm is locked in an immobile position by a solenoid operated armature shaft when the swing arm is placed in the park position. The armature shaft is in direct contact with said swing arm when said swing arm is in the locked position. The armature shaft releases the swing arm from the locked position upon actuation of the vehicle ignition system and depression of the vehicle brake pedal. The swing arm includes a stress line that will cause the swing arm to break along the stress line before, the swing arm is moved out of the park position if excessive force is applied to the swing arm. In addition, the swing arm is capable of both rotational and rocking movement about a common pivot point.
