Overview
The ZF 6057.018.395 CONTROL UNIT is a precision-engineered electronic assembly that governs hydraulic pressure modulation and shift timing within the WG210 transmission series. Positioned on the valve body interface, this OEM genuine part interprets input from the transmission control module to direct clutch and brake application. The SKU 6057.018.395 ensures exact-fit replacement for maintaining factory-specified shift quality and torque converter lockup behavior. Without this unit, the transmission cannot execute commanded gear changes, making it a critical component for driveline reliability in heavy-duty industrial applications.
Symptoms of Failure
- Erratic shift timing or harsh engagement — When the 6057.018.395 control unit degrades, hydraulic signals become inconsistent, causing delayed or abrupt gear changes that worsen under load.
- Transmission stuck in limp mode — A failing control unit often triggers fault codes that force the WG210 into a single-gear safe mode, drastically limiting vehicle speed and torque output.
- Intermittent loss of forward or reverse — Worn internal solenoids or corroded contacts within the control unit can cause complete loss of drive in one direction, often mistaken for clutch failure.
- Erratic torque converter lockup — Drivers may notice unexpected shuddering or RPM fluctuation during highway cruising as the control unit fails to regulate lockup pressure correctly.

Compatibility
This control unit is specifically designed for the ZF WG210 series transmission. Based on its hydraulic architecture and connector configuration, it also fits the WG180, WG200, and WG211 models when used with the appropriate valve body adapter plate. Always verify the transmission serial number against the OEM parts catalog before installation. The unit interfaces directly with the 4657101078: TRANSMISSION HOUSING and mounts between the 4657201166: HOUS.FRONT SECT and the 4657201168: HOUSING REAR PART. For complete rear sealing, the 4657298101: HOUSING REAR SECTION must be properly torqued to prevent fluid contamination of the control unit.

Frequently Asked Questions
Q: Can the 6057.018.395 control unit be repaired, or must it be replaced?
A: This unit is a sealed, non-serviceable assembly. Internal solenoid wear or circuit board damage cannot be reliably repaired in the field. Replacement with the OEM genuine part is the only recommended solution to restore proper shift function.
Q: Does this control unit require programming after installation?
A: Yes. The 6057.018.395 must be calibrated to the specific transmission using ZF diagnostic software. Without proper coding, shift pressures and timing will default to incorrect values, potentially causing immediate drivability issues.
Q: What torque specification should be used for the mounting cap screws?
A: Use 12 Nm (106 in-lbs) for the M8 cap screws (part 0636100801) and 8 Nm (71 in-lbs) for the M6 cap screws (part 0636100803). Always use a calibrated torque wrench to avoid housing distortion.
