1. A shift system, comprising:
a selector fork moveable between a first shift position and a second shift position;
an actuator operable for moving the selector fork between its first and second shift positions; and
a state machine for controlling actuation of the actuator, wherein the state machine is operable to correct a position of the actuator, in the event of a shift request into the first shift position or into the second shift position, on the basis of a stored mechanical backlash and a sign generated by the state machine and associated with the corresponding shift request.
