Abstract
A latching shifter with override feature is interfaced with a shift-by-wire transmission, wherein the latching of the shifter with respect to a gear cam is autonomously synchronized to a gear selected by the electronics of the transmission whenever the shifter is physically at another gear via autonomous actuation of a gear synchronization cam having an inclined cam follower guide surface. The incline urges the cam follower under its inherent biasing into the gear notch corresponding to the gear selected by the electronics of the transmission.
