ZF 6057.018.196 CONTROL UNIT for WG190 | OEM Genuine Part

Overview

The ZF 6057.018.196 CONTROL UNIT is a precision electro-hydraulic valve body designed specifically for the WG 190 series transmission. This OEM genuine part governs shift timing, pressure modulation, and clutch engagement within the transmission’s main control circuit. Mounted directly on the TRANSMISSION HOUSING, it interprets electronic signals from the vehicle’s ECU to actuate hydraulic solenoids. The SKU 6057.018.196 is a direct replacement unit that restores factory-spec shift quality and prevents erratic behavior in heavy-duty applications.

Symptoms of Failure

• Erratic or delayed shifting under load: When the control unit fails, the transmission may hesitate or slam into gear during acceleration, particularly when towing or climbing grades.
• Intermittent loss of forward or reverse gears: A failing 6057.018.196 can cause sudden neutral conditions, requiring the operator to cycle the ignition to regain drive.
• Hydraulic fluid contamination from solenoid debris: Internal wear in the control unit can shed metallic particles into the oil, clogging the SCREEN SHEET and reducing line pressure.
• Transmission overheating with no diagnostic codes: A stuck valve within the control unit can cause continuous clutch slippage, generating excessive heat without triggering a check-engine light.

Technical Specifications

Compatibility

This control unit is engineered for the ZF WG 190 series but is also compatible with the WG 180 and WG 200 transmissions when used with the correct FIXING PLATE adapter. It fits all WG 190 variants, including the WG 190-110, WG 190-120, and WG 190-130. For installations in the WG 200 series, verify that the HOUS.FRONT SECT and HOUSING REAR PART align with the control unit’s mounting bosses. The unit also interfaces with the HOUSING REAR SECTION on later production models.
