Overview
The ZF 4657.101.410 TRANSMISSION HOUSING is the primary structural core of the WG210 series gearbox, serving as the rigid enclosure that supports the planetary gear sets, clutch packs, and valve body. As an OEM genuine part, this housing ensures precise alignment of rotating assemblies and maintains hydraulic pressure integrity throughout the transmission. The SKU 4657.101.410 is specifically machined to accept the HOUS.FRONT SECT (4657201027) and the HOUSING REAR PART (4657201012), forming a complete sealed assembly that channels lubrication and cooling oil to critical wear surfaces.
Symptoms of Failure
- External oil seepage at mating flanges: Cracks or warpage in the housing cause fluid to escape between the TRANSMISSION HOUSING (4657101033) and the front section, leading to low oil levels and eventual gear slippage.
- Persistent gear engagement noise: Distortion of the housing bore misaligns shafts, producing a whining or grinding sound during acceleration that worsens under load.
- Intermittent pressure loss: Hairline fractures in the housing wall allow hydraulic pressure to bleed off, causing delayed shifts or complete loss of drive in forward gears.
- Contaminated oil from casting debris: Internal corrosion or spalling of the housing surface sheds metallic particles into the fluid, clogging the CYLINDRICAL PIN (0631306792) passages and reducing filter efficiency.

Compatibility
This housing is engineered for the WG 210 Series transmissions, including the WG180, WG200, WG210, and WG240 models. It directly replaces the earlier TRANSMISSION HOUSING (4657101033) used in pre-2015 builds, offering improved oil channel geometry for better heat dissipation. The housing also interfaces with the HOUS.FRONT SECT (4657201027) and HOUSING REAR PART (4657201012) to form a complete assembly for WG200 and WG240 variants.
