Overview
The ZF 4642.101.047 TRANSMISSION HOUSING is a critical structural component engineered specifically for the WG 150 series. This OEM genuine part forms the rigid outer shell that encloses the gear train, torque converter, and hydraulic valve body, ensuring precise alignment of all internal rotating assemblies. As the primary load-bearing casing, it absorbs torsional stresses and maintains oil circulation pathways. The SKU 4642.101.047 is precision-machined from high-grade cast iron to withstand extreme thermal cycling and mechanical loads found in heavy-duty industrial applications.
Symptoms of Failure
- External oil seepage at mating surfaces: A worn or cracked housing often causes transmission fluid to weep from the bell housing or side cover joints, leading to low fluid levels and eventual overheating.
- Abnormal gear engagement noise: When the housing distorts, bearing bores lose concentricity, producing a distinct whining or grinding sound during acceleration or deceleration.
- Persistent clutch slip under load: Internal cracks in the housing can disrupt hydraulic passages, reducing clutch pack pressure and causing erratic shifting or delayed engagement.
- Visible hairline fractures near mounting bosses: Stress fractures typically develop around the 0631311009: GROOVED STUD locations, compromising structural integrity and requiring immediate replacement.

Compatibility
This housing is designed for the ZF WG 150 series but also fits select variants of the WG 180 and WG 200 transmissions when used with the correct 4642301207: TRANSMISSION HOUSING adapter kit. It is compatible with all WG 150 models manufactured after 2012, including the WG150-6, WG150-8, and WG150-10 configurations. For proper identification, always verify the 0730365067: TYPE PLATE on your existing unit before ordering. The housing also integrates with the 4642301168: SCREEN SHEET for oil filtration and the 4642301169: SCREEN SHEET for debris protection.
