Abstract
A mechanical transmission gear shifting assembly connected to a transmission with multiple gear selectors that, when moved in a back and forth motion, selects different gear ratios via a cam with a cam follower for moving gear selectors, in response to the same active cam surfaces. The assembly additionally includes a retractable stop dog, and detents for moving, stopping and holding the cam at all times, such that the cam moves in increments corresponding to sequentially increasing or decreasing selected gear states of the transmission.
