Abstract
Some embodiments are directed toward a transmission having a torque input and output, drive members selectively engageable for sequentially changing gear ratio between the torque input and output, the transmission also having a shaft with a shifting feature. The transmission includes a drum having a track around its outer perimeter and arranged such that torque can be transferred by rotating the shaft, the drum capable of being moved along the length of the shaft, a biasing mechanism for urging the drum towards a rest position along the length of the shaft, and a drive member selector member provided in operative relation to the track, wherein by rotating the shaft the drive member selector member can be selectively urged into contact with a first drive member for drivingly engaging therewith in a first torque connection or into contact with a second drive member for drivingly engaging in a second torque connection.
