Overview
The ZF 0501.313.618 SOLENOID VALVE is a critical electro-hydraulic actuator responsible for directing oil flow within the WG200 and WG201 transmission valve bodies. This OEM genuine part precisely modulates clutch and brake application pressure, ensuring smooth gear shifts and torque converter lock-up. As a direct replacement for the original factory component, the SKU 0501.313.618 restores factory shift quality and prevents erratic transmission behavior. This solenoid valve sits directly on the valve body assembly, adjacent to the 4644105413 DISCONNECTION mechanism and the 4644101040 TRANSMISSION HOUSING, making it a core element of the hydraulic control circuit.
Symptoms of Failure
- Erratic or delayed gear engagement: When the solenoid valve fails, you may experience a noticeable lag when shifting from Neutral to Drive or Reverse, often accompanied by a harsh clunk.
- Intermittent gear slipping under load: A worn 0501.313.618 can cause the transmission to slip out of gear during acceleration, particularly in 2nd or 3rd gear, as hydraulic pressure fluctuates.
- Transmission fluid leaks near the valve body: Internal seal degradation on this solenoid often leads to external oil seepage around the valve body area, leaving visible drips on the 4642303093 OUTPUT FLANGE.
- Check engine or transmission warning light: A failing solenoid valve triggers diagnostic trouble codes (DTCs) related to pressure control or solenoid circuit faults, often accompanied by a stuck-in-gear condition.

Compatibility
This solenoid valve is engineered specifically for the ZF WG200 and WG201 series transmissions. It is a direct fit for models including the WG180, WG200, WG201, and WG211. The part is commonly used in industrial vehicles, agricultural tractors, and construction equipment that utilize these ZF powershift transmissions. Always verify the valve body configuration before installation; the 0501.313.618 replaces the original solenoid in the pressure control module. For full assembly integrity, ensure the 0636021010 HEXAGON SCREW is torqued to specification during reinstallation.
