A reversing transmission including a planetary gear mechanism comprised of helical gears. The carrier of the ring gear forms part of the sealed enclosure for the mechanism and is connected to the output shaft through splines to thereby permit axial movement of the ring gear. A normally engaged spring biased clutch is provided between the input shaft and the ring gear carrier. A caliper brake is provided for braking and stopping of the rotation of the planetary gear cage. Because of the helical teeth of the gears, the braking will cause the ring gear carrier to move against the bias of the spring to disengage the clutch and, as the cage is brought to a stop, the direction of rotation of the ring gear and thus, the output shaft is reversed.
