ZF 6057.018.122 CONTROL UNIT for WG210 | OEM Genuine Part

Overview

The ZF 6057.018.122 CONTROL UNIT is a critical electronic module within the WG210 series transmission assembly. This OEM genuine part governs hydraulic pressure modulation and shift timing, directly managing clutch pack engagement and torque converter lockup. Positioned on the valve body inside the transmission sump, the 6057.018.122 interprets input from the vehicle’s ECU to ensure precise gear changes under varying load conditions. As a direct replacement unit, it restores factory-spec communication between the transmission control system and the mechanical components housed within the 4657101079: TRANSMISSION HOUSING.

Symptoms of Failure

• Erratic shifting or delayed engagement: When the control unit fails, the transmission may hesitate before engaging drive or reverse, often accompanied by harsh shifts between gears.
• Intermittent limp mode activation: A worn 6057.018.122 can trigger fault codes that force the transmission into a protective limp-home mode, limiting speed and gear range.
• Torque converter shudder: Loss of precise solenoid control within the unit leads to irregular lockup, causing vibration during cruising speeds.
• No communication with diagnostic tools: Complete electrical failure of the control unit prevents scan tools from reading transmission data, mimicking a dead module.

Technical Specifications

Compatibility

This control unit is engineered for the ZF WG210 series, but cross-referencing with the 4657201166: HOUS.FRONT SECT and 4657201169: HOUSING REAR PART confirms its use in WG180, WG200, and WG250 variants where the electronic interface matches. It also integrates with the 4657298104: HOUSING REAR SECTION in certain off-highway applications. Always verify the harness connector pattern against your existing unit before installation.
