ZF 6009.092.557 CONTROL UNIT for WG210 | OEM Genuine Part

Genuine ZF CONTROL UNIT (Part No. 6009.092.557). This part fits: 6 WG 210. Found in: Loose Parts. Also referenced as: 6009092557 / 6009.092.557 / 6009 092 557.

Overview

The ZF 6009.092.557 CONTROL UNIT is a critical electronic-hydraulic interface module designed specifically for the WG 210 Series powershift transmission. This OEM genuine part governs shift timing, clutch pressure modulation, and torque converter lock-up sequencing. Positioned on the valve body assembly within the transmission sump, the 6009.092.557 unit receives electrical signals from the vehicle ECU and converts them into precise hydraulic commands. For proper sealing and alignment, this control unit mounts directly against the 4657101039: TRANSMISSION HOUSING, ensuring oil galleries remain pressurized during operation.

Symptoms of Failure

  • Erratic shift hunting under load: When the control unit loses calibration, the WG210 may cycle between gears unpredictably during uphill hauling or heavy towing.
  • Delayed forward engagement from neutral: A worn 6009.092.557 often causes a 3-5 second lag before the transmission engages Drive, particularly after cold starts.
  • Intermittent loss of reverse gear: Internal solenoid degradation within this control unit can cause reverse to drop out entirely, then suddenly return after a system reset.
  • Transmission fault code P07xx with limp-home mode: The control unit’s pressure sensors frequently trigger diagnostic trouble codes, forcing the transmission into a single-gear safety mode.

Compatibility

This control unit is engineered for the ZF WG 210 Series transmission family. It is directly compatible with WG180, WG200, and WG210 models found in mid-range construction loaders, telescopic handlers, and agricultural tractors. The unit also cross-references to certain WG150 variants when used with the appropriate 4657201028: HOUS.FRONT SECT adapter. For rear-mounted applications, verify fitment with the 4657201013: HOUSING REAR PART to ensure proper solenoid clearance. Always secure the assembly using the 0631306792: CYLINDRICAL PIN for precise dowel alignment during installation.
