ABSTRACT:
A transmission includes an input shaft aligned along an axial direction and mounted for rotation, an output shaft, a plurality of gears selectively connectable between the input shaft and the output shaft for providing a plurality of gear ratios between the input shaft and the output shaft, and a plurality of shift rails movable in the axial direction to select various ones of the plurality of gears, the shift rails having connectors operable to move the shift rails in the axial direction. A shift member is mounted both for movement in the axial direction and for rotational movement about the axial direction, and an interlock is engageable by the shift member and mounted for rotation about the axial direction. The interlock is provided with a slot, so that rotation of the shift member rotates the interlock. Rotation of the interlock by the shift member enables the slot to index to a plurality of positions in alignment with the connectors, and alignment of the slot with one of the connectors enables the shift rail associated with that connector to be moved in the axial direction to select one of the plurality of gears.
