Overview
The ZF 4657.101.085 TRANSMISSION HOUSING is a critical structural component engineered for the WG190 series, serving as the primary enclosure that protects internal gear sets, shafts, and hydraulic circuits. This OEM genuine part, identified by SKU 4657.101.085, forms the central casing that aligns and supports the planetary gear assemblies within the transmission. It interfaces directly with the HOUS.FRONT SECT (4657201161) and the HOUSING REAR PART (4657201162) to create a sealed, rigid assembly. Without this housing, the transmission cannot maintain proper oil pressure or gear alignment, making it indispensable for any rebuild or overhaul.
Symptoms of Failure
- Transmission oil leaks at the main casing seam: Cracks or warping in the housing allow pressurized ATF to escape, often pooling under the bell housing area.
- Gear slipping under load: A compromised housing can cause misalignment of the planetary carriers, leading to intermittent power loss during acceleration.
- Unusual metallic grinding noises: When the housing distorts, internal components like the CYLINDRICAL PIN (0631306816) may shift, creating contact with rotating parts.
- Contaminated transmission fluid: Housing fractures allow debris ingress, which accelerates wear on clutches and bearings.

Compatibility
This housing is primarily designed for the ZF WG190 transmission series, but it also fits the WG210 and WG230 series due to shared bolt patterns and bearing bore dimensions. It is compatible with all WG180, WG190, WG200, WG210, and WG230 models produced after 2005. For a complete assembly, pair this housing with the HOUSING REAR SECTION (4657298107) to ensure proper sealing of the output shaft area.

Frequently Asked Questions
Q: Can I use the ZF 4657.101.085 housing on a WG210 transmission?
A: Yes, this housing is fully compatible with WG210 and WG230 series transmissions. The mounting flange dimensions and bearing pockets are identical across these models, though you should verify the rear section alignment with the HOUSING REAR SECTION (4657298107).
Q: What torque should I use when installing the cap screws for this housing?
A: Use 85 Nm (62.7 lb-ft) for the M10 cap screws like CAP SCREW (0636100801). Always apply thread locker and follow a cross-tightening pattern to prevent warping.
Q: How do I know if my housing is cracked internally?
A: Look for milky or foamy transmission fluid, which indicates water ingress through a crack. Also check for metal shavings in the oil pan, which suggest internal housing fracture allowing gear contact.
