Overview
The ZF 6009.065.276 CONTROL UNIT is a critical electro-hydraulic component that governs shift timing and pressure modulation within the WG 210 transmission series. Positioned on the valve body assembly, this OEM genuine part interprets electronic signals from the vehicle’s ECU to direct hydraulic flow to clutches and brakes. The SKU 6009.065.276 ensures precise solenoid response, directly impacting torque delivery and gear engagement. Without a functioning control unit, the transmission cannot execute commanded shifts, making this part essential for maintaining driveline integrity in heavy-duty applications.
Symptoms of Failure
- Erratic or delayed gear engagement – When the 6009.065.276 control unit degrades, you may experience a noticeable lag between shifting commands and actual gear changes, especially under load.
- Intermittent transmission slipping – A failing control unit can cause inconsistent hydraulic pressure, leading to clutch slip during acceleration or uphill driving.
- Harsh or jarring shifts – Worn solenoid valves within the unit produce abrupt upshifts or downshifts, often accompanied by a metallic clunk.
- Check transmission light activation – Fault codes related to solenoid circuit malfunctions or pressure regulation errors frequently trace back to a compromised 6009.065.276 control unit.

Compatibility
This control unit is engineered for the ZF WG 210 series, but it also cross-fits select models in the WG180, WG200, and WG250 families where the valve body interface matches. Always verify the transmission serial number against the 6009.065.276 specification before installation. The unit integrates directly with the TRANSMISSION HOUSING and mounts adjacent to the HOUS.FRONT SECT and HOUSING REAR PART. Secure alignment is maintained via the CYLINDRICAL PIN, which prevents rotational movement during high-vibration operation.
