ZF 0501.320.897 GASKET for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 0501.320.897 GASKET for WG100/WG130/WG131 is a precision-engineered OEM genuine sealing component designed to maintain hydraulic integrity within ZF’s WG-series automatic transmissions. This gasket, identified by SKU 0501.320.897, sits between the transmission housing and valve body interface, preventing pressurized oil from bypassing critical fluid passages. By creating a leak-proof barrier, it ensures consistent clutch engagement and torque converter lock-up performance. As a factory-spec part, it guarantees exact fitment and material compatibility with the original assembly, eliminating the risk of premature failure associated with aftermarket substitutes.

Symptoms of Failure

• External oil seepage at the housing joint: A worn 0501.320.897 gasket often causes visible transmission fluid drips around the mating surface between the 4143101022: HOUSING and the valve body, leading to low fluid levels.
• Erratic gear engagement or delayed shifts: Internal fluid bypass due to a degraded gasket reduces line pressure, causing harsh or slipping shifts, particularly under load.
• Cross-contamination of hydraulic circuits: A compromised seal allows oil to mix between separate channels, resulting in unintended clutch application or torque converter shudder.
• Overheating transmission: Insufficient sealing forces the pump to work harder, generating excess heat that accelerates wear on adjacent components like the 4143301044: HOUSING.

Technical Specifications

Compatibility

This gasket is specifically engineered for ZF WG100, WG130, and WG131 transmission models. It is also compatible with the WG180 and WG200 series when used in conjunction with the 0631329135: SPRING PIN for alignment. For applications requiring additional sealing integrity, pair this gasket with the 0636302014: SCREW PLUG to secure the housing ports. Always verify the transmission serial number against the OEM parts catalog before installation.
