ZF 6009.047.342 CONTROL UNIT for WG200 | OEM Genuine Part

Overview

The ZF 6009.047.342 CONTROL UNIT is a critical electronic module that governs shift timing and pressure regulation within the WG200 transmission series. Positioned on the valve body assembly, this OEM genuine part interprets input from the transmission control module to actuate solenoids, ensuring precise gear engagement. The SKU 6009.047.342 is engineered to ZF’s original specifications, providing direct plug-and-play replacement for failed units. Without this component, the transmission cannot execute commanded shifts, making it essential for restoring factory performance in heavy-duty applications.

Symptoms of Failure

• Erratic shifting or delayed engagement — When the 6009.047.342 control unit degrades, you may experience harsh upshifts or a noticeable lag when moving from neutral to drive. This is a common long-tail search query for “ZF WG200 transmission shifting problems.”
• Transmission stuck in limp mode — A failing control unit often triggers fault codes that force the gearbox into a single-gear safety mode. Operators searching for “ZF transmission limp mode fix” will find this part relevant.
• Intermittent loss of gear selection — The unit may cause random dropouts where the transmission fails to hold a gear under load, leading to RPM surges. This symptom is frequently searched as “transmission gear slipping under load.”
• No electrical response from solenoids — If the control unit fails internally, solenoids receive no power, resulting in a complete loss of hydraulic pressure. This is often diagnosed as “transmission not responding to shift commands.”

Technical Specifications

Compatibility

This ZF 6009.047.342 CONTROL UNIT is specifically designed for the WG200 series transmissions, including models such as WG180, WG200, and WG210. It is also compatible with select variants of the Ecomat series that share the same valve body architecture. Always verify your transmission model number before ordering. The unit interfaces directly with the TRANSMISSION HOUSING (4644101223) and TRANSMISSION HOUSING (4644301225), which provide the structural mounting points. For proper identification, ensure the TYPE PLATE (0730365125) matches your unit, and use the COVER PLATE (4644301298) to seal the control unit cavity against contaminants.
