Abstract
The present invention broadly comprises a gear selector assembly including a tube with at least one engagement feature, arranged to be disposed within a drive shaft for a transmission, the transmission including at least one gear and the drive shaft including at least one gear actuation assembly; and a differential rotation element coupled with the tube and arranged to be coupled with the drive shaft so that the tube is differentially rotatable with respect to the drive shaft. The tube is arranged to differentially rotate such that the engagement feature engages the actuation assembly and the transmission engages a respective gear from the at least one gear. The assembly includes a means for displacing a portion of the differential rotation element such that the tube axially and rotationally displaces with respect to the drive shaft. The portion axially and rotationally engages with an interface element to controllably position the tube.
