  • Patent number: 4129046
    Abstract: An improved gear shift control for use in motor vehicle transmissions of the type wherein gear shifter forks are slidably mounted on associated elongated shifter rails within the housing of the transmission. The gear shift control includes a selector gate mounted within the transmission cover for rotation about a first axis transverse to the longitudinal axis of the shifter rails. A shift lever is mounted within the gate for rotation about a second axis, generally perpendicular to and intersecting the first axis, the lower end of the shift lever being selectively engageable with the shifter forks for movement of the shifter forks on their associated shifter rails. Tabs extend laterally from the lower end of the selector gate to selectively engage at least one shifter fork to prevent movement thereof during movement of another shifter fork. Opposed springs are provided to center the selector gate in a neutral position between changes in shifter fork positions.
