Abstract
A transmission includes a main shaft, a first input shaft, a second input shaft, and a first clutch to drivingly couple the main shaft and the first input shaft. A second clutch drivingly couples the main shaft and the second input shaft. A torque converter is selectively driven by one of the first input shaft and a first speed gear set. The first speed gear set is driven by the other of the first input shaft and the torque converter. A second speed gear set is driven by the second input shaft.
