Drive Range-High






Engine torque is transmitted to the converter then through the forward clutch, to the input ring gear in a clockwise direction. The direct clutch is applied, transmitting torque through the sun gear drive shell to the sun gear in a clockwise direction. Since both the sun gear and the planet pinions are turning in a clockwise direction at the same speed the planetary gear sets are locked and turn as one unit in direct drive.
