The ZF 0501209719 transmission speed sensor is an inductive pulse sensor designed for ZF automatic and automated manual transmissions used across passenger car and commercial vehicle applications. It monitors rotational speed at the transmission output or torque converter, sending continuous signal pulses to the transmission control unit for precise shift timing and torque converter lock-up control. This sensor serves as a cross-reference replacement for Audi/VW part number 01L927321, covering applications including Audi A8, A6, S6, S8, RS6, and Volkswagen Phaeton with 4.2L and 6.0L engines. It also cross-references to LIUGONG 30B0081 and various industrial equipment numbers including John Deere AL156798 and JCB 717/20065. The sensor features a sealed connector design and is constructed to withstand prolonged exposure to transmission fluid, temperature fluctuations, and vibration in demanding drivetrain environments.
