Overview
The ZF 6007.203.147 POSITION SENSOR is a critical electronic component engineered specifically for the WG 201 Series transmission family. This OEM genuine part monitors the exact rotational position of the transmission output shaft, relaying real-time data to the control unit for precise gear engagement and shift timing. Mounted directly within the transmission housing, the sensor ensures that the WG201 operates within its optimal performance envelope. The SKU 6007.203.147 is the direct replacement for the factory-installed unit, guaranteeing seamless integration without the need for adapter harnesses or software recalibration.
Symptoms of Failure
When the ZF 6007.203.147 position sensor begins to degrade, operators often notice erratic gear hunting during highway cruising, as the transmission loses confidence in shaft speed data. A second common failure sign is delayed or harsh engagement when shifting from Neutral to Drive or Reverse, particularly after the transmission has warmed up. You may also experience intermittent loss of cruise control functionality or a check transmission light accompanied by a P0720 or P0722 diagnostic trouble code. In severe cases, the transmission may enter a limp-home mode, locking itself into a single gear to prevent internal damage.

Compatibility
This position sensor is factory-specified for the ZF WG 201 Series, including the WG180, WG200, WG201, and WG210 models commonly found in medium-duty trucks, buses, and off-highway equipment. It is also backward-compatible with earlier WG 200 Series transmissions that use a 5V Hall-effect sensor interface. Always verify that your transmission control module (TCM) firmware supports the PWM output characteristic of the 6007.203.147 before installation. For complete assembly integrity, we recommend pairing this sensor with a new 0634306198 O-RING and a 0634801098 SEALING RING to prevent fluid ingress.
Related Components
During a full transmission overhaul, several surrounding components should be inspected and replaced concurrently. The 4644101203 TRANSMISSION HOUSING and 4644301382 TRANSMISSION HOUSING provide the structural mounting points for this sensor. Additionally, the 4644301189 THREADED BUSH and 0636302005 SCREW PLUG are often replaced during sensor service to ensure a leak-free seal.
