ABSTRACT:
A multi-speed countershaft transmission for a vehicle is provided. The transmission includes a main shaft and countershaft gears that receive input directly from an input member. A plurality of torque transmitting mechanisms may be selectively applied to synchronize a range gear to a countershaft. The countershaft transfers torque to an output gear set, which may transfer torque to a planetary gear set. The available range gears include a plurality of forward speed ratios and at least one reverse speed ratio. One or more power take-off sections may also be provided.
