Abstract:
1. A vehicle transmission comprising a main shaft having an input end, an output end spaced from the input end, and at least one main shaft gear positioned between the input end and the output end for common rotation with the main shaft, a plurality of countershafts spaced from and substantially parallel to the main shaft, at least one countershaft gear selectively rotatable about one of the plurality of countershafts and the at least one countershaft gear intermeshing with the at least one main shaft gear, a planetary gear set including a plurality of planet gears and a gear carrier rotatable about the output end of the main shaft and supporting the plurality of planet gears, a first torque transmitting mechanism selectively engageable to hold the planet gears stationary relative to the gear carrier, an output shaft coupled to the planet gear carrier for rotation therewith, a sleeve shaft concentric with and rotatable around the output end of the main shaft, a second torque transmitting mechanism arranged to selectively lock the sleeve shaft to the main shaft for common rotation therewith, and an output gear set including a first output gear coupled for rotation with the sleeve shaft and a second output gear coupled for rotation with one of the plurality of countershafts and intermeshing with the first output gear, wherein the first output gear is the only gear coupled for rotation with the sleeve shaft and intermeshing with a gear coupled for rotation with one of the plurality of countershafts.
