Abstract:
A transmission includes an input member, an output member, and an intermediate member coaxially aligned with the input member and the output member. The transmission further includes at least one countershaft substantially parallel with the input member, output member and the intermediate member, and at least one gear associated with each of the input member, the output member, intermediate member, at least one countershaft. The transmission also includes a planetary gear set to operatively couple a gear of the at least one gear associated with the intermediate shaft with the output shaft, and a plurality of clutches to selectively define a torque transfer path from the input member to the output member via one or more of the intermediate member, first countershaft, second countershaft, and the at least one associated gears therewith. The plurality of clutches include a direct drive clutch to selectively couple the input member directly to the intermediate member.
