Abstract
A mechanical shift control system, for use on manual transmissions, employing a number of shifter forks mounted on a single stationary rail. The shifter forks engage sleeves, clutches or other similar elements of a transmission to shift the transmission between selected gear shift ratios. A set of stacked levers movable in parallel planes drive respective gear shift forks reciprocally along the stationary rail. For actuation of a lever, a selector shaft is employed extending in a plane perpendicular to the movement of the levers. The selector shaft reciprocates laterally through the various planes of lever movement to positions corresponding to a particular lever actuation and rotates in each plane to move a selected lever in a direction corresponding to a selected gear ratio.
