Overview
The ZF 4616.298.962 SEAL KIT is a critical OEM genuine service component engineered specifically for the WG 65 series transmission. This kit contains all necessary sealing elements—including O-rings, gaskets, and lip seals—required to restore hydraulic integrity within the transmission’s valve body and clutch housing assembly. By replacing worn elastomers, the 4616.298.962 prevents pressurized oil from migrating between circuits, ensuring consistent shift quality and torque delivery. This seal kit is often installed during a major overhaul alongside the 4616101101 TRANSMISSION HOUSING and the 0636011118 HEXAGON SCREW to secure the assembly.
Symptoms of Failure
- External oil seepage at the transmission housing joint: When the seal kit degrades, hydraulic fluid may weep from the mating surface between the main case and the 4616301304 HOUSING, leaving visible drips on the bell housing.
- Erratic or delayed gear engagement: Worn seals allow internal pressure loss, causing sluggish shifts or momentary neutral conditions during acceleration under load.
- Contaminated transmission fluid with metallic debris: Failed seals permit clutch material to circulate, accelerating wear on adjacent components like the 4616301309 HOUSING.
- Audible whining or hissing from the transmission: Air ingestion through compromised seals creates cavitation noise, particularly in cold-start conditions.

Compatibility
This seal kit is designed exclusively for the ZF WG 65 series transmission family. It is compatible with the following models: WG65, WG80, WG100, WG120, WG150, WG180, and WG200. The kit interfaces directly with the valve body cover and the clutch piston housing. For complete assembly, always pair this seal kit with the 0636011038 HEXAGON SCREW and the 0636016015 HEXAGON SCREW to achieve proper clamping torque. Additionally, verify the condition of the 0631306085 CYLINDRICAL PIN and the 0634313118 O-RING during installation to prevent secondary leaks.
