Remotely actuated two-way roller clutch assembly

An over-running clutch assembly for an automotive transmission comprises an outer race having a cylindrical inner surface and an inner race engaged with a drop shaft of the transmission and having a cammed outer surface coaxial with the cylindrical inner surface and defining a gap therebetween and a roller clutch disposed within the gap; a biasing element to bias the roller clutch to a disengaged position; and an actuator to selectively overcome the biasing element to engage the roller clutch and lock the outer race and inner race and prevent relative rotation between the outer race and inner race, thereby preventing rotation of the drop shaft and movement of the automobile.
