ZF 6009.092.673 CONTROL UNIT for WG210 | OEM Genuine Part

Overview

The ZF 6009.092.673 CONTROL UNIT is a critical electronic-hydraulic interface module designed specifically for the WG 210 series transmission. This OEM genuine part governs shift timing, pressure modulation, and clutch engagement sequences within the valve body assembly. As the brain of the transmission’s hydraulic logic, the 6009.092.673 interprets input signals from the vehicle’s ECU and converts them into precise spool valve movements. The unit integrates directly with the TRANSMISSION HOUSING and is secured by the CYLINDRICAL PIN for alignment stability. When replacing this control unit, technicians often inspect the HOUS.FRONT SECT and HOUSING REAR PART for wear, as these components form the sealed environment around the unit.

Symptoms of Failure

• Erratic shifting or gear hunting — The transmission fails to hold a gear under load, frequently upshifting and downshifting without driver input. This often stems from degraded solenoid response within the 6009.092.673.
• Delayed engagement from Neutral to Drive — A noticeable 2-3 second pause before the transmission engages forward motion, indicating internal valve sticking or electrical signal loss in the control unit.
• Transmission fluid contamination with metallic debris — Worn internal seals or cracked circuit boards allow fine metal particles to circulate, often visible during oil changes. This symptom accelerates damage to the TRANSMISSION HOUSING and adjacent hydraulic circuits.
• Intermittent loss of reverse gear — The control unit fails to route pressure to the reverse clutch pack, causing sporadic reverse operation that worsens with heat buildup.

Technical Specifications

Compatibility

This control unit is engineered for the ZF WG 210 series but is also compatible with WG 180, WG 200, and WG 250 transmissions when used with the appropriate adapter harness. It directly replaces OEM units in ZF 6WG210, 5WG210, and 4WG210 variants. The 6009.092.673 interfaces with the HOUS.FRONT SECT and HOUSING REAR PART to create a sealed hydraulic chamber. For proper installation, verify that the CYLINDRICAL PIN aligns with the unit’s locating bore to prevent misalignment during reassembly.
