Abstract: A shift fork lock system for a transmission includes a shift rail extending along a rail axis. The shift rail is movable axially along and rotatably around the rail axis. The shift fork lock system further includes a shift fork having an internal surface defining a bore along the rail axis. The shift rail extends through the bore and is movable axially and rotatably relative to the shift fork when the shift fork is in a decoupled configuration. The shift rail is rotatable to a first rotational position and a coupled configuration such that the shift fork is coupled to and movable with the shift rail along the rail axis. The shift rail is rotatable to a second rotational position and the decoupled configuration such that the shift fork is decoupled from the shift rail to facilitate movement of the shift rail independent of the shift fork along the rail axis.
