ZF 6009.047.591 CONTROL UNIT for WG200 | OEM Genuine Part

Overview

The ZF 6009.047.591 CONTROL UNIT is a critical electronic module that governs hydraulic valve actuation within the WG 200 Series transmission. This OEM genuine part, identified by SKU 6009.047.591, sits directly on the valve body assembly and interprets input signals to regulate clutch pressure and shift timing. It interfaces seamlessly with the 4644101220: TRANSMISSION HOUSING and the 4644301221: TRANSMISSION HOUSING to ensure precise fluid routing. Without this control unit, the transmission cannot execute gear changes or maintain torque converter lockup.

Symptoms of Failure

• Erratic shift timing or gear slipping – The control unit fails to send proper signals, causing delayed or harsh engagement between gears.
• Transmission stuck in limp mode – A degraded 6009.047.591 unit often forces the WG200 into a single-gear safety mode, limiting vehicle speed to 30-40 mph.
• Intermittent loss of communication – Faulty internal circuitry leads to sporadic CAN bus errors, triggering dashboard warning lights and erratic behavior.
• No response to gear selector input – The unit may completely stop processing commands, leaving the transmission in neutral or park regardless of driver selection.

Technical Specifications

Compatibility

This control unit is engineered for the ZF WG200 Series transmissions, including models such as WG180, WG200, and WG210. It is also backward-compatible with certain WG150 variants when used with the appropriate 0730365067: TYPE PLATE for identification. For secure mounting, pair it with the 0631311009: GROOVED STUD to ensure proper grounding and vibration resistance. Always verify your transmission serial number against the OEM reference before installation.
