Overview
The ZF 6057.018.142 CONTROL UNIT is a precision electro-hydraulic valve body that governs shift timing and pressure modulation within the WG210 transmission series. Mounted directly on the main valve block, this OEM genuine part interprets electronic signals from the transmission control module (TCM) to direct hydraulic flow to clutches and bands. The SKU 6057.018.142 serves as the central command interface, converting electrical commands into smooth gear engagements. For optimal sealing and structural integrity, this control unit interfaces with the 4657101082: TRANSMISSION HOUSING, which encloses the entire hydraulic circuit.
Symptoms of Failure
- Erratic shifting or delayed engagement — When the control unit loses calibration, you may experience harsh upshifts or a noticeable lag when moving from Neutral to Drive, a common search query for “ZF WG210 shift delay fix.”
- Transmission fluid contamination — Internal solenoid wear can introduce metallic particles into the oil, leading to “ZF transmission black fluid” issues that accelerate wear on the 4657201166: HOUS.FRONT SECT.
- Intermittent limp mode activation — A failing control unit often triggers fault codes P0700 or P0740, causing the transmission to lock in second gear, a symptom frequently searched as “WG210 limp mode causes.”
- Oil leaks at the valve body interface — Cracking in the control unit housing can allow ATF to seep past gaskets, pooling near the 4657201170: HOUSING REAR PART.

Compatibility
This control unit is engineered for the ZF WG210 series, but its valve body architecture also supports the WG180, WG200, and WG211 models. It is a direct replacement for earlier 6057.018.140 and 6057.018.141 revisions. The unit mounts securely to the 4657298102: HOUSING REAR SECTION, ensuring proper alignment with the shift solenoids. Always verify your transmission serial number before ordering, as WG150 and WG250 variants use a different solenoid configuration.
