A transmission range selector system having a driver interface module, an electronic control module, and an actuator coupleable to an automotive transmission. The driver interface module may be positioned in a plurality of desired transmission gear positions. The desired gear position set at the driver interface module is redundantly sensed by the combination of a rotational position Hall effect sensor and a plurality of discrete position Hall effect sensors. The rotational position Hall effect sensor has a linearly varying output representative of the desired gear position. The Hall effect sensors provide an output to the electronic control module for energizing the actuator to change the transmission gear position to the desired transmission gear set at the driver interface module. The actuator may include multiple motors to provide redundancy and a sensor gear for providing transmission gear position feedback to the electronic control module.
