Overview
The ZF 6057.018.259 CONTROL UNIT is a critical electro-hydraulic component within the WG211 transmission series. This OEM genuine part functions as the central command module, regulating clutch pressure and shift timing to ensure smooth gear transitions under heavy load. Positioned on the valve body assembly, the SKU 6057.018.259 directly interfaces with the transmission’s hydraulic circuits to modulate oil flow. When paired with a robust 4657101049: TRANSMISSION HOUSING, this control unit maintains precise actuation for consistent performance in commercial vehicles and industrial machinery.
Symptoms of Failure
- Erratic shifting or gear hunting: A worn control unit causes delayed or harsh shifts, often triggering “limp mode” in WG211 transmissions.
- Transmission fluid contamination: Internal seal degradation leads to metallic debris in the oil, visible during routine drain intervals.
- Intermittent loss of drive: The unit may fail to engage specific gears under load, particularly during low-speed maneuvering or hill climbs.
- Diagnostic fault codes P0700-P0790: Solenoid circuit errors appear on scan tools, indicating electrical failure within the control module.

Compatibility
This control unit is engineered for the ZF WG211 series, but it also fits select WG180, WG200, and WG250 transmissions produced after 2015. The unit is compatible with both 4-speed and 6-speed variants when used with the correct 4657301130: HOUS.FRONT SECT and 4657301131: HOUSING REAR PART. Always verify the valve body configuration before installation, as the 0631306816: CYLINDRICAL PIN alignment is critical for proper hydraulic sealing.

Frequently Asked Questions
Q: Can I install this control unit without replacing the transmission housing?
A: Yes, the 6057.018.259 is a standalone module. However, inspect the TRANSMISSION HOUSING for cracks or warping, as misalignment can cause premature failure.
Q: How do I know if my WG211 needs this specific control unit?
A: Check the valve body casting for “6057.018.259” stamped near the solenoid bank. Units with damaged CYLINDRICAL PIN bores often require this exact replacement.
Q: What torque specs apply to the mounting bolts?
A: Use 25 Nm for the CAP SCREW (M10) and 18 Nm for the CAP SCREW (M8) when securing the control unit to the HOUS.FRONT SECT.
