Overview
The ZF 6057.018.313 CONTROL UNIT is a critical electronic module within the WG191 transmission series, responsible for managing hydraulic pressure modulation and shift timing. Positioned on the valve body assembly, this OEM genuine part (SKU: 6057.018.313) interprets input from the transmission control module to actuate solenoids, ensuring precise gear engagement. Without this unit, the WG191 cannot execute commanded shifts, making it essential for drivetrain reliability in heavy-duty commercial vehicles.
Symptoms of Failure
- Erratic or delayed shifting: A failing control unit often causes harsh or delayed gear changes, particularly when accelerating from a stop. This is a common search query for “ZF WG191 shift hesitation.”
- Transmission stuck in limp mode: When the 6057.018.313 unit malfunctions, the WG191 may default to a single gear, limiting vehicle speed. Operators searching for “transmission stuck in gear ZF” frequently encounter this issue.
- Intermittent loss of communication: Faulty internal circuitry can trigger diagnostic trouble codes (DTCs) for solenoid circuit errors, leading to “check engine” lights and reduced performance.
- Oil contamination from internal shorts: Electrical failures within the control unit can cause overheating, degrading transmission fluid and producing a burnt smell—a symptom often searched as “burning transmission fluid ZF.”

Compatibility
This control unit is engineered for the ZF WG191 series, but it also fits select variants of the WG180, WG200, and WG210 transmissions used in municipal trucks, buses, and construction equipment. Always verify your transmission model tag before installation. The unit interfaces directly with the 4657101049: TRANSMISSION HOUSING and the 4657301130: HOUS.FRONT SECT to ensure proper alignment. Additionally, the 4657301131: HOUSING REAR PART and 0631306816: CYLINDRICAL PIN are often replaced concurrently to prevent misalignment issues.

Frequently Asked Questions
Q: Can the 6057.018.313 control unit be repaired, or must it be replaced?
A: Due to sealed electronics and proprietary firmware, ZF recommends replacement rather than repair. Attempting to open the unit often damages the PCB beyond salvage.
Q: How do I know if my WG191 needs a new control unit versus a solenoid?
A: Use a diagnostic scanner. If DTCs point to “control module internal fault” (e.g., P0601), replace the unit. Solenoid faults (P0740-P0750) typically require solenoid replacement instead.
Q: Is the 6057.018.313 compatible with 24V electrical systems?
A: Yes, this unit is designed for both 12V and 24V systems, making it suitable for heavy trucks and buses with dual-voltage architectures.
