Overview
The ZF 4657.262.002 TUBE for WG210 is a precision-engineered fluid conduit that directs pressurized hydraulic oil within the transmission’s valve body and clutch pack circuits. As an OEM genuine part, this tube ensures consistent flow rates and pressure integrity during gear shifts. It sits between the main housing and the front section, directly interfacing with the TRANSMISSION HOUSING and the HOUS.FRONT SECT. The SKU 4657.262.002 is manufactured to ZF’s exacting tolerances, making it a critical component for maintaining shift quality in WG210 series transmissions.
Symptoms of Failure
- Hydraulic oil leaks around the tube connection points – Worn seals or cracks in the tube cause external seepage, often visible as drips near the housing joint.
- Delayed or harsh gear engagement – A compromised tube reduces line pressure, leading to sluggish shifts or abrupt clutch application.
- Transmission overheating – Restricted oil flow from a deformed or blocked tube increases internal friction and thermal buildup.
- Intermittent slipping under load – Loss of hydraulic pressure from a leaking tube causes clutch packs to slip during acceleration or hill climbing.

Compatibility
This tube is designed for ZF WG210 series transmissions, but it also fits select models in the WG180, WG200, and WG250 families where the hydraulic circuit layout is identical. It is commonly used in ZF 6WG210, 5WG210, and 4WG210 variants. Always verify the tube routing against the HOUSING REAR PART and the CYLINDRICAL PIN alignment before installation.
