ABSTRACT:
An underdrive transmission incorporates a planetary gear assembly including a sub-assembly which may be shifted manually between high and low-range modes to establish direct and reduction ratio drive. In the high-range mode, the drive path is from an input member directly through the carrier to an output member, with the gears unloaded. In the low-range mode, the sun gear is grounded to the housing through a reaction plate, and the drive path is from the input member to the ring gear and from the carrier to the output member. The sub-assembly includes a slidable shift sleeve on which are supported the sun gear, carrier and planet gears.
