Overview
The ZF 0636.610.096 STUD is a precision-engineered fastening component designed for the WG 201 series transmission. This OEM genuine part, identified by SKU 0636.610.096, serves as a critical locating and clamping stud within the transmission housing assembly. It ensures secure alignment of mating surfaces, particularly when mounting the TRANSMISSION HOUSING (part number 4644101160) or the TRANSMISSION HOUSING (part number 4644301323). By providing a fixed, threaded anchor point, this stud maintains structural integrity under high torque loads and thermal expansion, preventing misalignment of internal gear sets.
Symptoms of Failure
- Oil seepage around the housing joint: A worn or stripped 0636.610.096 stud can compromise the seal between the transmission housing and cover, leading to gradual fluid loss. This is often noticed as a “ZF WG201 oil leak near bell housing” issue.
- Transmission housing vibration or looseness: When the stud fails to maintain clamping force, the housing may shift slightly, causing a “WG200 series transmission housing wobble” during operation. This can be felt as driveline shudder under load.
- Difficulty achieving proper torque specs: A damaged stud thread prevents the SCREW PLUG (4475280043) or other fasteners from seating correctly, resulting in “ZF transmission stud thread stripping” and incomplete assembly.
- Metallic debris in transmission fluid: As the stud wears, fragments may break off and circulate, often described as “ZF WG201 metal shavings in oil pan” during routine maintenance.

Compatibility
This stud is primarily engineered for the ZF WG 201 series transmissions, including models such as WG180, WG200, and WG210. It is also compatible with select variants of the ZF Ecomat and ZF Ecolife series where similar housing fastening points are used. Always verify fitment by cross-referencing the SKU 0636.610.096 with your transmission’s parts catalog. For complete assembly, consider pairing this stud with the THREADED BUSH (4644301189) to ensure proper thread engagement and load distribution.
