Overview
The ZF 6057.018.064 CONTROL UNIT is a critical electro-hydraulic module that governs shift timing and pressure regulation within the WG210 transmission series. Mounted directly to the valve body assembly, this OEM genuine part interprets electronic signals from the vehicle’s ECU to actuate solenoids and spools, ensuring precise gear engagement. The SKU 6057.018.064 is engineered to withstand high thermal loads and continuous duty cycles, making it essential for maintaining driveline integrity in heavy-duty applications. This control unit interfaces seamlessly with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to form a sealed, pressurized circuit.
Symptoms of Failure
- Erratic or delayed shifting under load: A worn control unit often causes harsh upshifts or delayed downshifts, especially when towing or climbing grades. This is a common search query for “ZF WG210 transmission shift hesitation.”
- Transmission fluid contamination from internal leakage: Degraded seals within the unit allow hydraulic fluid to bypass, leading to low line pressure and burnt clutch packs. Technicians frequently search for “WG200 control unit fluid leak symptoms.”
- Intermittent loss of reverse or forward gears: Electrical failures in the solenoid driver circuit can cause complete loss of a gear range, often misdiagnosed as a valve body issue. This aligns with “ZF transmission no reverse WG180.”
- Persistent diagnostic trouble codes (DTCs) for pressure control: Fault codes P0740 or P0745 often trace back to a failing control unit rather than the solenoids themselves.

Compatibility
This control unit is primarily designed for the WG210 series but also fits select variants of the WG180, WG200, and WG250 transmissions used in municipal trucks, refuse vehicles, and off-highway equipment. It is not backward-compatible with early WG119 models without adapter harness modifications. When replacing this unit, always inspect the HOUSING REAR PART and the HOUSING REAR SECTION for cracks or corrosion that could compromise the new control unit’s seal.

Frequently Asked Questions
Q: Can the 6057.018.064 control unit be repaired, or must it be replaced?
A: Due to the sealed solenoid coils and proprietary circuit board potting, ZF does not authorize field repairs. Replacement with this OEM genuine unit is the only reliable solution to restore factory shift quality.
Q: Does this control unit require programming after installation?
A: Yes. The unit must be calibrated to the specific transmission using ZF’s diagnostic software (e.g., ZF-Testman). Failure to perform a learn procedure may result in harsh shifts or limp-home mode.
Q: How often should the screen sheets (4657301032 and 4657301033) be replaced alongside the control unit?
A: ZF recommends replacing both screen sheets whenever the control unit is swapped, as debris from the old unit often clogs these filters within the first 50 operating hours.
