Land Rover Part Number: STC4444 - Speed Transducer
STC4444 is a speed transducer fitted to the transmission switch, harness and shift mechanism on Discovery 2 (L318) and to the valve body main control and servos on Range Rover 4.4 V8 5-speed Steptronic (L322). It produces the vehicle speed signal used by these automatic transmission systems and provides the electronic input required for gear selection and transmission control logic. Accurate speed input supports correct shift timing and interaction between the valve body and control electronics; replacing a faulty transducer restores the transmission's speed feedback and is carried out during transmission or valve body servicing where applicable.
