Overview
The ZF 4642.101.114 TRANSMISSION HOUSING is the primary structural shell for the WG150 series transmission. It encases the gear train, valve body, and torque converter assembly, providing precise alignment and protection against external contaminants. As an OEM genuine part, SKU 4642.101.114 ensures exact fitment and material integrity, directly replacing worn or damaged housings to restore hydraulic pressure integrity and gear mesh accuracy. This housing integrates with the 4642301213: TRANSMISSION HOUSING variant for specific WG150 configurations, and it mounts the 0730365125: TYPE PLATE for identification purposes.
Symptoms of Failure
- External oil seepage from housing seams: Cracks or porosity in the 4642.101.114 housing allow transmission fluid to escape, often visible as drips under the bellhousing area.
- Gear engagement hesitation or slipping: Warpage or bolt-hole elongation misaligns the valve body, causing delayed shifts or clutch pack slip under load.
- Abnormal whining or knocking noises: Bearing bore wear in the housing leads to shaft runout, producing metallic sounds during acceleration or deceleration.
- Contaminated fluid with metallic debris: Internal fractures release aluminum or steel particles into the oil, visible during drain intervals.

Compatibility
This housing is engineered for the WG150 series but also fits select variants of the WG180 and WG200 transmissions due to shared bellhousing patterns. It is not compatible with WG120 or WG250 models without adapter kits. Always verify the casting number against your existing unit. The housing accommodates the 0631311009: GROOVED STUD for secure mounting and the 4642301168: SCREEN SHEET for oil filtration within the sump area.
