Overview
The ZF 0750.147.164 HOSE PIPE is a critical fluid transfer component engineered specifically for the WG 200 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 gear train. Positioned along the upper casing assembly, the 0750.147.164 hose pipe connects directly to the 4644101176: TRANSMISSION HOUSING and the 4644301371: TRANSMISSION HOUSING, forming a sealed conduit that prevents fluid loss under high-pressure operation. Without this precise pipe, the transmission cannot maintain proper hydraulic pressure, leading to inefficient gear engagement and accelerated wear.
Symptoms of Failure
- Hydraulic oil seepage at the hose pipe connection – Visible fluid accumulation around the pipe ends or along the housing seam indicates a cracked or degraded 0750.147.164 hose pipe, often accompanied by a burnt transmission fluid smell.
- Erratic gear engagement or delayed shifting – When this pipe fails to deliver consistent oil flow, the transmission may hesitate between gears or produce harsh shifts, especially under load.
- Overheating transmission warning – A compromised hose pipe restricts oil circulation to the cooler, causing the transmission to run hotter than normal, which can trigger dashboard alerts or thermal shutdown.
- Low transmission fluid level without external leaks – Internal weeping from the pipe into the bell housing can mimic a slow leak, requiring inspection of the 0730365067: TYPE PLATE area for proper identification.

Compatibility
This genuine ZF hose pipe is primarily designed for the WG 200 Series transmissions, including models WG200, WG210, and WG220. It also fits select WG180 variants that share the same hydraulic circuit layout. The pipe interfaces with the 0631311009: GROOVED STUD for secure mounting, and its sealing integrity depends on the condition of the adjacent 0634306525: O-RING. Always verify the part number stamped on the original pipe before replacement to ensure correct fitment for your specific transmission serial number.
