Abstract
According to a preferred embodiment of the present invention, a clutch is applied when the vehicle comes to a stop. The application of this clutch locks the output shaft with energy stored therein. When the shift selector is then moved to the park position, the clutch releases the stored energy in a controlled manner by slipping the clutch plates. The controlled slipping reduces the noise as the park pawl tooth contracts an output gear tooth.
