ZF 6029.201.361 PLUG for WG210/WG94 | OEM Genuine Part

Overview

The ZF 6029.201.361 PLUG is a critical sealing component engineered for the WG210 and WG94 series transmissions. This OEM genuine part, identified by SKU 6029.201.361, functions as a threaded closure element within the transmission housing assembly. It prevents fluid contamination and maintains hydraulic pressure integrity at specific access points. The plug is typically installed on the TRANSMISSION HOUSING to seal inspection or fill ports, ensuring the internal environment remains free of debris and moisture. Without this component, the transmission system loses its ability to sustain proper lubrication flow, leading to accelerated wear on internal gears and bearings.

Symptoms of Failure

• Transmission fluid seepage around the housing port: A worn or stripped 6029.201.361 plug allows oil to escape, leaving visible wet spots on the HOUS.FRONT SECT or bell housing area.
• Contaminated hydraulic fluid causing gear hesitation: When the plug fails to seal, dirt and moisture enter the system, leading to sluggish shifting or delayed engagement in WG210 and WG94 models.
• Audible air ingestion during cold starts: A compromised seal can allow air to enter the lubrication circuit, producing a whining or hissing noise from the transmission pump.
• Intermittent low-pressure warnings on the dashboard: Loss of fluid through the plug port reduces overall system pressure, triggering warning lights during heavy load operations.

Technical Specifications

Compatibility

This plug is specifically designed for ZF WG210 and WG94 series transmissions. It is also compatible with the WG180, WG200, and WG250 models that share the same housing architecture. The 6029.201.361 part interfaces directly with the HOUSING REAR PART and the HOUSING REAR SECTION in these transmissions. Always verify the thread pitch and port location before installation, as variations exist between early and late production runs of the WG94 series.
