ABSTRACT:
A manual transmission includes an input shaft operatively connected to a source of motive power and a countershaft in axially parallel relationship with the input shaft. The manual transmission also includes an output shaft in axially parallel relationship with the counter shaft. The manual transmission further includes a plurality of gear set pairs disposed between the input shaft and the counter shaft such that the gear sets provide different gear ratios for transferring torque from the input shaft to the output shaft, each of the gear sets including a driver gear operatively supported by the input shaft such that the driver gear receives only torque from the source of motive power.
