Abstract
In a special operating mode, a controller is programmed to disengage a hydraulically actuated park mechanism without use of engine power. The starter motor is used to rotate the engine-driven pump at sufficient speed to command disengagement of Park. Once park is disengaged, a holding pin is used to maintain the out of park condition without hydraulic pressure or flow.
