Overview
The ZF 2094.009.006 T 7336 PS is an OEM genuine hydraulic control unit designed to manage clutch pressure and lubrication flow within ZF powershift transmissions. Positioned in the valve body assembly, this precision component directs oil to specific clutches based on gear selection, ensuring smooth engagement and reliable torque transfer. The SKU 2094.009.006 is a direct replacement for original equipment, manufactured to ZF’s exact tolerances for construction machinery applications. This part integrates with the 2094101014: TRANSMISSION HOUSING to form the main structural enclosure, while the 2094301046: HOUSING and 2094298053: HOUSING provide additional mounting points for valve spools and pressure regulators.
Symptoms of Failure
- Delayed or harsh gear engagement: Worn internal seals cause pressure loss, leading to hesitation when shifting from neutral to drive or reverse.
- Transmission overheating: A failing control unit restricts oil flow to the cooler, causing elevated operating temperatures during heavy loading.
- Intermittent clutch slip under load: Degraded spool valves fail to maintain steady hydraulic pressure, resulting in momentary power loss when climbing grades or pushing material.
- External oil seepage at valve body joints: Cracks in the casting or deteriorated O-rings allow fluid to escape, often visible as drips near the transmission side cover.

Compatibility
This control unit is engineered for ZF WG series powershift transmissions commonly used in wheel loaders, telehandlers, and excavators. It is a direct fit for the following models: WG180, WG200, WG211, and WG250. Always verify the transmission serial number before installation, as internal valve configurations may vary by production year. The 0630361034: SEALING CAP should be replaced concurrently to prevent contamination ingress at the pressure test port.
