Overview
The ZF 6057.018.671 CONTROL UNIT is a critical electronic actuator module specifically engineered for the WG 160 Series transmission. This OEM genuine part governs hydraulic pressure modulation and shift timing, ensuring precise gear engagement within the valve body assembly. As the brain of the transmission control system, the 6057.018.671 interprets input signals to regulate clutch and brake application. This SKU is a direct replacement unit designed to restore factory performance in heavy-duty commercial vehicles and off-highway machinery.
Symptoms of Failure
- Erratic or delayed shifting under load: When the control unit wears, the transmission may hesitate or harshly slam into gear, particularly during uphill climbs or when towing heavy loads.
- Intermittent loss of forward or reverse gears: A failing 6057.018.671 can cause sudden neutral conditions, leaving the vehicle stranded until the system is power-cycled.
- Transmission stuck in limp-home mode: The control unit may trigger a fault code that forces the gearbox into a single gear (typically 2nd or 3rd) to prevent further damage, drastically reducing road speed.
- Oil contamination from internal short circuits: Electrical failures within the unit can burn transmission fluid, producing a distinct acrid smell and dark, gritty oil on the dipstick.

Compatibility
This control unit is primarily designed for the ZF WG 160 series, but it also cross-fits select models in the WG 180 and WG 200 families due to shared hydraulic architecture. It is commonly found in ZF Ecomat 4HP and 5HP variants used in municipal buses, fire trucks, and construction loaders. Always verify your transmission serial number against the 6057.018.671 to ensure correct solenoid resistance matching. The unit interfaces directly with the 4656101055: TRANSMISSION HOUSING and the 4656201075: HOUS.FRONT SECT to seal the valve body cavity. For rear-mounted applications, it works in tandem with the 4656201076: HOUSING REAR PART and the 4656298047: HOUSING REAR SECTION to maintain structural integrity.

Frequently Asked Questions
Q: Can the 6057.018.671 be repaired, or must it be replaced?
A: Due to the sealed electronic design and proprietary firmware, ZF does not offer serviceable components inside this control unit. Replacement with the OEM genuine 6057.018.671 is the only reliable solution to restore proper shift logic and avoid recurring fault codes.
Q: How do I know if my WG 160 needs a new control unit versus a simple recalibration?
A: If you have already performed a transmission adaptation reset using diagnostic software and the symptoms persist (especially gear slippage or limp mode), the internal solenoids or circuit board are likely compromised. A physical inspection for burnt fluid or corrosion on the connector pins confirms the need for replacement.
Q: Does this part include the necessary gaskets and seals?
A: The 6057.018.671 ships as the bare control unit only. You will need to order the 4656301148: FIXING PLATE and appropriate 0636100817: CAP SCREW separately to complete the installation.
