Overview
The ZF 4642.199.767 LOOSE PARTS kit is a critical service component engineered specifically for the WG 201 Series transmission. This genuine OEM assembly contains the necessary loose hardware and fasteners required to secure internal transmission elements during a rebuild or major repair. Positioned within the main casing, this kit interfaces directly with the TRANSMISSION HOUSING (4644101160) and the TRANSMISSION HOUSING (4644301323), ensuring that all bearing caps, valve body covers, and shift mechanisms remain properly torqued. The SKU 4642.199.767 is a factory-sealed package that eliminates guesswork by providing every loose part needed for a single assembly point.
Symptoms of Failure
When the components within the 4642.199.767 kit degrade or are improperly installed, operators will notice distinct operational issues. Transmission fluid seepage around the housing mating surfaces is a primary indicator, often traced back to worn fasteners or missing hardware. Intermittent gear slippage under load occurs when loose parts fail to maintain clamping force on clutch packs. Audible rattling or vibration from the bell housing suggests that retaining hardware has loosened, allowing internal components to shift. Erratic shift timing can also develop when the THREADED BUSH (4644301189) or SCREW PLUG (4475280043) lose their seating integrity, causing pressure loss in the hydraulic circuit.

Compatibility
This loose parts kit is designed for the ZF WG 201 Series, but its application extends to several related transmission models that share the same housing architecture. It is fully compatible with the WG180, WG200, and WG210 series transmissions. The kit also fits select variants of the Ecomat 4HP and 6HP families where the housing interface matches the WG201 pattern. Always verify that your transmission serial number falls within the WG201 production range before ordering. For complete assembly, pair this kit with the O-RING (0634306198) and TYPE PLATE (0730365067) for proper identification and sealing.
