Abstract
An electric shift mechanism for an automotive transmission mechanism is disclosed in which a manual selector lever is universally mounted on a support adapted for sequentially pivoting north-south and east-west swingable rockers about associated intersecting axes. A gate limiting plate formed with a predetermined shift pattern is mounted on the support intermediate the rockers. The lower end of the lever has a ball follower for pre-loaded travel on a single cam track supported longitudinally on the east-west rocker. The cam track is contoured to simulate shift effort stability and feel of conventional manual gear shifting operations. The rockers allow crossover movement from a neutral lever position to preselect a desired gate for reciprocal fore and aft travel of the ball follower to selected transmission shift positions.
