1. A selector mechanism comprising:
a selector interface having a detent member, the selector interface being rotationally operable about a rotational axis;
an artificial feel positioner that defines a plurality of artificial feel positions that correspond to selectable positions of the selector interface, wherein the plurality of artificial feel positions are connected via a screw channel that helically extends along the artificial feel positioner;
a motor that rotationally operates the artificial feel positioner to automatically operate the detent member through the screw channel to move the detent member and the selector interface to a desired position of the detent member and the selector interface, wherein the desired position is a predetermined rotational position of the selector interface with respect to the rotational axis, and wherein the screw channel of the artificial feel positioner includes a profile that is concentric to the rotational axis of the selector interface.
