Overview
The ZF 4616.329.006 CONNECTION COVER is a critical sealing and structural component for the WG 65 series transmission. This OEM genuine part, identified by SKU 4616.329.006, mounts directly to the rear of the transmission housing, enclosing the output shaft assembly and preventing contamination from entering the drivetrain. It serves as the primary interface between the 4616105402 OUTPUT and the main casing, ensuring that hydraulic pressure is maintained within the system. Without this cover, the transmission cannot retain lubrication or protect internal gears from debris.
Symptoms of Failure
When the 4616.329.006 connection cover deteriorates, operators often notice these specific failure modes:
- External oil seepage at the rear bell housing: A worn gasket or cracked cover allows transmission fluid to escape, leaving puddles under the vehicle.
- Contaminated transmission fluid: Dirt and moisture enter through a compromised seal, leading to premature wear on the 4005303005 OUTPUT FLANGE.
- Abnormal driveline noise: Loss of structural integrity causes vibration or rattling from the output area, especially during load shifts.
- Gear engagement hesitation: Pressure loss from a leaking cover can delay clutch pack actuation, mimicking slipping symptoms.

Compatibility
This connection cover is engineered for the WG 65 Series family of ZF transmissions. It is directly compatible with the following models: WG65, WG80, WG100, WG120, WG150, WG180, and WG200. The part also fits select variants of the WG 55 Series when used with the 4616101119 TRANSMISSION HOUSING. Always verify the bolt pattern matches your specific housing before installation, as the 0636011038 HEXAGON SCREW set must be replaced concurrently to ensure proper clamping force.
