ABSTRACT:
A drive range selection employs both a movable shift actuating member that is operatively connected to a customary manual shift valve and a movable park lock actuating member that is operatively connected to a parking lock pawl mechanism. A force transfer device operatively connects the shift actuating member and the park lock actuating member to a selecting lever. Mechanism is provided to disengage the force transfer device from the shift actuating member when the force transfer device is operatively connected to the park actuating member, and to immobilize the shift actuating member in response to activation of the park lock actuating member when the force transfer device is disengaged from the shift actuating member. Provision is further made not only to disengage the force transfer device from the park lock actuating member when the force transfer device is operatively connected to the shift actuating member, but also to preclude movement of the park actuating member when the force transfer device is operatively connected to the shift actuating member. As such, when the selecting lever is placed in the park position by the vehicle operator, none of the drive ratios of the transmission are engageable. Rather, they are disengaged from the shift selecting member until such time as the operator removes said selecting lever from the park position. Conversely, when the selecting lever is in neutral or any one of the drive ranges, the park lock actuating mechanism cannot be activated.
