Overview
The ZF 2094.377.058 VALVE BLOCK is a critical hydraulic control component engineered for the WG100, WG130, and WG131 series transmissions. This OEM genuine part precisely directs transmission fluid to regulate clutch engagement and shift timing. Positioned within the main valve body assembly, the 2094.377.058 interfaces directly with the 2094101012: TRANSMISSION HOUSING to ensure consistent oil pressure delivery. As a factory-spec component, it guarantees exact fitment and long-term reliability for heavy-duty industrial applications.
Symptoms of Failure
- Erratic gear engagement or delayed shifting – Worn internal spools cause inconsistent hydraulic pressure, leading to harsh or hesitant shifts during operation.
- Transmission fluid leaks around the valve block – Degraded seals or cracked housing allow oil to escape, often pooling near the 2094301036: HOUSING interface.
- Loss of forward or reverse drive – A failing valve block may fail to route fluid to specific clutches, resulting in partial or total drive loss under load.
- Elevated operating temperatures – Internal blockages force the pump to work harder, generating excess heat and accelerating wear on adjacent components.

Compatibility
This valve block is specifically designed for ZF WG100, WG130, and WG131 transmissions. It also fits select variants of the WG180 and WG200 series when used with the appropriate 2094298057: HOUSING adapter. Always verify your transmission model and serial number before installation. For proper sealing, pair this part with a new 2094301071: COVER to prevent contamination.
