ZF 0750.147.231 HOSE PIPE for WG150 | OEM Genuine Part

Overview

The ZF 0750.147.231 HOSE PIPE is a critical fluid transfer component engineered specifically for the WG 150 Series transmission. This OEM genuine part channels pressurized hydraulic oil between the valve body and the cooler circuit, ensuring consistent lubrication and thermal regulation within the gearbox. As an integral element of the transmission’s hydraulic architecture, the SKU 0750.147.231 connects directly to the TRANSMISSION HOUSING (4642101109) and the TRANSMISSION HOUSING (4642301205), forming a sealed pathway that prevents pressure loss. Without this hose pipe, the WG150 cannot maintain the precise oil flow required for clutch engagement and gear shifting.

Symptoms of Failure

• External hydraulic oil leaks near the transmission bell housing – Cracks or abrasions in the hose pipe allow ATF to escape, leaving puddles under the vehicle and reducing fluid levels.
• Erratic gear engagement or delayed shifting – A compromised hose pipe causes pressure drops in the hydraulic circuit, leading to soft shifts or failure to engage specific gears.
• Overheating transmission fluid – Restricted flow through a collapsed or kinked hose pipe prevents proper oil cooling, triggering thermal warnings or burnt fluid odor.
• Whining or groaning noise from the transmission pump – Air ingestion through a damaged hose pipe creates cavitation, producing audible distress during operation.

Technical Specifications

Compatibility

This hose pipe is primarily designed for the ZF WG 150 Series, but it also fits select variants of the WG180 and WG200 transmissions due to shared hydraulic routing. The 0750.147.231 is compatible with all WG150 models produced after 2005, including those equipped with the TYPE PLATE (0730365125) and the GROOVED STUD (0631311009) for mounting. Always verify your transmission’s serial number against the OEM parts catalog to ensure correct fitment.
