Abstract
A transmission uses a chain and sprocket final drive that provides all final drive torque multiplication in addition to transferring power to the differential axis. The transmission includes a front support structure that provides for a small driving sprocket. The front support includes an insert made of hardened material that can serve as the inner bearing race for the driving sprocket. In some embodiments, four fluid passageways are provided to the torque converter. In some embodiments, the park gear may be integrated with the driven sprocket.
