ZF 0501.322.459 GASKET for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 0501.322.459 GASKET is a precision-engineered sealing component designed for the WG100, WG130, and WG131 series transmissions. This OEM genuine part sits between the transmission housing and the valve body or cover plate, creating a leak-proof barrier that maintains hydraulic pressure within the clutch and gear circuits. The SKU 0501.322.459 is manufactured to ZF’s exacting tolerances, ensuring a perfect fit and long service life. When installed alongside a 4143101009 HOUSING or a 4143301025 HOUSING, this gasket prevents fluid migration between critical oil passages, directly supporting shift quality and torque converter lock-up performance.

Symptoms of Failure

When the 0501.322.459 gasket degrades, operators typically notice three distinct failure modes. First, external oil leaks appear at the housing mating surface, often dripping onto the bell housing or under the transmission pan. Second, erratic or delayed gear engagement occurs as internal cross-leaks reduce clutch apply pressure, causing “flare shifts” between 2nd and 3rd gear. Third, low transmission fluid pressure triggers warning lights or harsh downshifts, particularly during cold starts. A worn gasket can also allow debris to bypass the filter, accelerating wear on the 0634313603 O-RING and 4475280018 SCREW PLUG.

Technical Specifications

Compatibility

This gasket is specifically engineered for ZF’s WG-series powershift transmissions. Confirmed compatible models include WG100, WG130, and WG131. It also fits select variants of the WG180 and WG200 series when used in conjunction with the correct 4143298457 SEAL KIT. For high-torque applications, pairing this gasket with a 0501342341 SUPPORT RING prevents extrusion under peak pressure. Always verify the housing face condition before installation; a warped 4143101009 HOUSING may require replacement to achieve proper sealing.
