Abstract: The shifter assembly comprises a shifter lever that can be moved according to a first movement to perform shift operations involving changing gearshift positions for controlling a vehicle transmission in at least one mode of operation, and according to a second movement to perform select operations to change between at least two different modes of operation, and a sensing unit comprising a magnetic sensor to detect both rotational and displacement movements of at least one magnet to identify whether shift or select operations are being performed by the shifter lever. The magnet is arranged to perform a rotational movement relative to the magnetic sensor according to one of the first or second movements of the shifter lever, and to perform a displacement movement relative to the magnetic sensor according to the other of the movements of the shifter lever.
