Overview
The ZF 4642.302.160 OIL FEED FLANGE is a critical lubrication component engineered specifically for the WG 150 series transmission. This OEM genuine part ensures precise oil delivery to the rotating clutch packs and planetary gear sets, maintaining hydraulic pressure and thermal stability during heavy-duty operation. Positioned between the TRANSMISSION HOUSING and the valve body, the flange channels filtered oil from the pump directly into the main shaft. The SKU 4642.302.160 is machined from high-strength aluminum alloy with precision-drilled passages to prevent flow restriction. When paired with a properly sealed TRANSMISSION HOUSING, this flange maintains the exact oil volume required for smooth gear engagement in ZF WG150 drivetrains.
Symptoms of Failure
- Oil leaks at the transmission housing interface – A worn or cracked 4642.302.160 flange allows pressurized ATF to seep past the gasket, leaving puddles under the bell housing and causing low fluid levels.
- Delayed or harsh gear engagement – When the oil feed flange loses its seal, hydraulic pressure drops, leading to sluggish shifts or sudden clunking when moving from neutral to drive.
- Overheating transmission with slipping clutches – Insufficient oil flow due to a blocked or deformed flange causes clutch packs to run dry, generating excessive heat and eventual torque converter shudder.
- Whining noise from the pump area – A restricted oil feed flange forces the transmission pump to cavitate, producing a high-pitched whine that worsens under load.

Compatibility
This oil feed flange is designed primarily for the ZF WG150 series, but it also fits select variants of the WG180 and WG200 transmissions when used with the correct GROOVED STUD kit. It is compatible with all WG150 models manufactured after 1998, including the WG150-6, WG150-8, and WG150-10. For WG180 and WG200 applications, verify that the TYPE PLATE on your housing confirms the same oil feed pattern. The flange is not interchangeable with older WG120 or WG130 series due to different bolt spacing.
