Overview
The ZF 4657.101.079 TRANSMISSION HOUSING is the central structural core of the WG190 and WG210 series transmissions. This OEM genuine part encloses the gear train, valve body, and hydraulic circuits, providing the rigid foundation required for precise gear alignment and torque transfer. As the main casing, it absorbs operational stresses and houses the lubrication channels that keep internal components cool. The SKU 4657.101.079 is a direct replacement engineered to ZF’s original tolerances, ensuring a seamless fit with adjacent assemblies such as the 4657201166: HOUS.FRONT SECT and the 4657201169: HOUSING REAR PART.
Symptoms of Failure
- External oil leaks around the bell housing area – Cracks or porosity in the housing allow transmission fluid to escape, often seen as drips under the vehicle after shutdown.
- Gear engagement hesitation or slipping – Warpage or distortion of the housing alters the alignment of shafts and clutches, leading to delayed shifts or unexpected neutral conditions.
- Abnormal vibration or whining noise during acceleration – A compromised housing can no longer dampen gear mesh vibrations, transmitting harshness through the driveline.
- Contaminated fluid from debris ingress – Fractures in the housing allow dirt and moisture to enter, accelerating wear on bearings and seals.

Frequently Asked Questions
Q: Can the 4657.101.079 housing be repaired if it has a small crack?
A: While some shops attempt aluminum welding, ZF recommends replacement due to the risk of distortion. A repaired housing may cause misalignment of the HOUS.FRONT SECT and lead to premature bearing failure.
Q: Does this housing include the oil feed passages for the WG210?
A: Yes, the casting is pre-machined with all internal oil galleries. You will still need the 0750301003: OIL FEED.HOUSG. to complete the external feed line connection.
Q: What torque specification should be used for the housing bolts?
A: For the M12 bolts securing this housing to the HOUSING REAR SECTION, use 80 Nm (59 ft-lbs) with a drop of medium-strength threadlocker. Always refer to the ZF service manual for your specific model.
