Overview
The ZF 6057.018.673 CONTROL UNIT is a precision electronic assembly that governs hydraulic pressure modulation within the WG190 transmission series. Positioned on the valve body, this OEM genuine part interprets shift commands and regulates clutch engagement for smooth gear transitions. The SKU 6057.018.673 is engineered to withstand high-temperature transmission fluid environments, ensuring consistent performance in heavy-duty commercial applications. When paired with the 4657101080: TRANSMISSION HOUSING, this control unit integrates seamlessly to maintain hydraulic circuit integrity.
Symptoms of Failure
- Erratic shift timing or harsh engagement: A failing control unit disrupts solenoid signals, causing delayed or jarring gear changes during acceleration.
- Transmission slipping under load: Worn internal electronics may fail to maintain clutch pressure, leading to power loss when climbing or hauling.
- Intermittent limp mode activation: Faulty sensor feedback triggers protective strategies, forcing the transmission into a reduced-performance state.
- Fluid contamination from degraded seals: Cracks in the unit’s housing allow debris to enter the hydraulic circuit, accelerating wear on adjacent components like the 4657201167: HOUS.FRONT SECT.

Compatibility
This control unit is specifically designed for the ZF WG190 series, but it also fits WG180 and WG200 models with identical valve body configurations. It is not compatible with WG210 or older WG150 units without adapter plates. For proper installation, ensure the 4657201171: HOUSING REAR PART and 4657298103: HOUSING REAR SECTION are free of cracks or warping, as misalignment can damage the control unit’s mounting flange.

Frequently Asked Questions
Q: Can the 6057.018.673 control unit be repaired, or must it be replaced?
A: This OEM unit is sealed and non-serviceable. Internal solenoid or circuit board failures require full replacement to avoid intermittent faults.
Q: How do I verify compatibility with my WG190 transmission?
A: Check the transmission serial number plate. Units built after 2015 use this control unit; earlier models may require the 6057.018.672 variant. Always inspect the TRANSMISSION HOUSING for updated bolt patterns.
Q: What torque specification applies to the mounting cap screws?
A: Use 12 Nm (106 in-lbs) for the CAP SCREW fasteners. Over-tightening can crack the control unit’s plastic connector housing.
