ABSTRACT:
A multi-speed, dual clutch transmission includes an input shaft, an output shaft, and first and second countershafts. The first and second countershafts are axially displaced from the input shaft, the output shaft and from one another. Four intermeshing gear pairs, an interconnecting gear set having first, second and third members, a first single gear and an idler gear, some of which are engageable with at least some of the shafts via a first clutch, a second clutch, and six torque-transmitting mechanisms, establish eight forward speed ratios and one reverse speed ratio. Furthermore, shifting between the forward speed ratios is dynamic.
