1. A shift actuator for a transmission, the shift actuator comprising:
a drive assembly coupled with a selector interface;
a transmission selector that operates between a plurality of transmission settings;
a threaded actuator rotationally operated by the drive assembly;
a carriage that linearly operates along the threaded actuator to define a plurality of actuator positions that correspond to the plurality of transmission settings; and
an actuator arm that extends between the carriage and the transmission selector to translate linear operation of the carriage to rotational operation of the transmission selector, wherein the actuator arm includes a positioning magnet that operates relative to a position sensor in communication with the drive assembly, wherein the positioning magnet and the position sensor cooperate to selectively operate a motor of the drive assembly between the plurality of transmission settings.
