description A transmission generally includes a shaft member having a continuous cylindrical surface portion longitudinally disposed next to a cylindrical outer surface portion interrupted by longitudinal grooves. A first gear assembly has a first clutch spring that holds a first set of rolling members between lobes that extend from a first output gear. A second gear assembly has a second clutch spring that holds a second set of rolling members between lobes that extend from a second output gear. The first gear assembly and the second gear assembly are configured to move longitudinally along the shaft member to a position where at least one of the first gear assembly and the second gear assembly is engaged for rotation with the shaft member when a value of torque at the shaft member is below a torque threshold value.
