ZF 6057.018.126 CONTROL UNIT for WG210 | OEM Genuine Part

Overview

The ZF 6057.018.126 CONTROL UNIT is a critical electronic module designed specifically for the WG210 series powershift transmission. This OEM genuine part governs hydraulic pressure modulation and shift timing, ensuring precise gear engagement under heavy load conditions. Mounted directly on the TRANSMISSION HOUSING, it interprets input signals from the vehicle’s ECU to actuate solenoid valves. The SKU 6057.018.126 is engineered to meet ZF’s original factory tolerances, making it a direct replacement for failed units in construction, mining, and agricultural machinery.

Symptoms of Failure

• Erratic gear shifting or slipping under load — A failing control unit often causes delayed or harsh shifts, particularly when the transmission is hot. This is a common search query for “WG210 shift hesitation” or “ZF transmission slipping in reverse.”
• Intermittent loss of forward or reverse gears — When the control unit’s internal circuit board degrades, the transmission may suddenly drop into neutral, requiring a full system reset.
• Diagnostic trouble codes (DTCs) for solenoid circuit faults — Operators frequently search for “ZF 6057.018.126 error code P07XX” as the unit fails to communicate with the valve body.
• Oil contamination in the electrical connector — Worn seals allow transmission fluid to wick into the control unit, causing corrosion and short circuits. This symptom often appears alongside leaks from the HOUS.FRONT SECT gasket.

Technical Specifications

Compatibility

This control unit is primarily validated for the ZF WG210 series, but it also fits earlier WG180 and WG200 variants when used with the correct wiring harness. It is not compatible with WG120 or WG250 models without adapter plates. The unit interfaces directly with the HOUSING REAR PART and the HOUSING REAR SECTION to complete the valve body assembly. Always verify your transmission’s serial number before ordering.
