Overview
The ZF 2094.355.001 HOUSING is a precision-machined structural component designed for heavy-duty construction machinery transmissions. This OEM genuine part serves as the primary enclosure for the clutch pack and hydraulic valve body within the transmission assembly. Located in the mid-section of the drivetrain, it provides critical alignment for the input shaft and supports the torque converter housing interface. The SKU 2094.355.001 is manufactured to ZF’s original tolerances, ensuring a leak-free seal and proper gear engagement under extreme loads. This housing works in concert with the 2094101012: TRANSMISSION HOUSING to form the complete structural backbone of the gearbox.
Symptoms of Failure
- Hydraulic fluid seepage at the bell housing joint: A worn 2094.355.001 housing often develops micro-cracks around bolt holes, causing oil to weep onto the clutch housing. This is a common “ZF transmission oil leak” issue in WG180 models.
- Erratic gear engagement under load: When the housing distorts from thermal cycling, the valve body alignment shifts, leading to delayed or harsh shifting—often searched as “ZF transmission slipping in forward gear.”
- Metallic debris in transmission fluid: Internal wear of the housing’s bearing seat allows the input shaft to wobble, generating fine metal particles. This symptom is frequently reported as “ZF transmission grinding noise when accelerating.”
- Torque converter misalignment: A warped housing face causes the converter to sit unevenly, producing a persistent vibration at idle that worsens under load.

Compatibility
This housing is engineered for ZF’s WG series powershift transmissions commonly used in wheel loaders, graders, and compact excavators. Based on its structural design and bolt pattern, the 2094.355.001 is compatible with the following ZF models: WG180, WG200, and WG210. It also fits select variants of the WG150 series when used with the appropriate 2094301036: HOUSING adapter kit. For WG200 transmissions, this part is often paired with the 2094298057: HOUSING to complete the rear support structure. Always verify the casting number against your existing unit before installation.
