Overview
The ZF 2094.152.009 HYDR.CONTROL is a critical hydraulic control unit that regulates oil flow and pressure within the transmission valve body of heavy-duty construction machinery. This OEM genuine part ensures precise clutch engagement and smooth gear shifts under extreme load conditions. The SKU 2094.152.009 is engineered to interface directly with the main 2094101012: TRANSMISSION HOUSING and the adjacent 2094301036: HOUSING, forming the hydraulic backbone of ZF power shift transmissions. Without this control unit, the transmission cannot modulate hydraulic pressure for directional changes or torque converter lockup.
Symptoms of Failure
- Erratic or delayed gear engagement: When the 2094.152.009 wears, operators experience hesitation when shifting from forward to reverse, especially under load.
- Internal hydraulic leaks: Damaged spool valves or seals cause oil to bypass, leading to low line pressure and visible drips near the 2094298057: HOUSING interface.
- Transmission overheating: A failing hydraulic control unit fails to route cooling oil properly, causing rapid temperature spikes during operation.
- Intermittent loss of drive: Worn internal passages cause pressure drops that make the transmission momentarily slip or lose power on inclines.

Compatibility
This hydraulic control unit is designed for ZF power shift transmissions commonly found in wheel loaders, graders, and dozers. It is a direct fit for the WG180 and WG200 series, as well as the WG150 and WG250 models. The unit mounts directly to the 2094301071: COVER assembly and interfaces with the main housing via a precision-machined gasket surface. Always verify your transmission model code before installation.
