ZF 4651.231.016 TUBE for WG100 | OEM Genuine Part

Overview

The ZF 4651.231.016 TUBE for WG100 is a precision-engineered fluid conduit designed to manage hydraulic oil flow within the transmission’s valve body and clutch pack assembly. This OEM genuine part, identified by SKU 4651.231.016, ensures consistent pressure delivery to critical shift elements, preventing erratic gear engagement. It is a direct-fit replacement for the WG 100 Series, where it interfaces with the TRANSMISSION HOUSING to maintain sealed oil passages. Without this tube, the transmission cannot sustain proper lubrication or hydraulic control.

Symptoms of Failure

• External oil leaks near the valve body: A cracked or corroded tube allows transmission fluid to escape, often leaving puddles under the vehicle and causing low fluid levels.
• Delayed or harsh gear shifts: When the tube loses its seal, hydraulic pressure drops, leading to slipping between gears or abrupt engagement during acceleration.
• Erratic clutch pack engagement: Inconsistent oil flow through a damaged tube causes shuddering or hesitation when shifting from neutral to drive or reverse.
• Overheating transmission: Reduced fluid circulation from a blocked or deformed tube increases internal friction, triggering thermal warnings or burnt fluid odor.

Technical Specifications

Compatibility

This tube is engineered for the ZF WG 100 Series, including models WG100, WG120, and WG150. It also fits select variants of the WG180 and WG200 transmissions when used with the HOUSING (4651301029) or the HOUSING (4651301024). Always verify your transmission’s serial number to confirm fitment, as the tube’s routing varies between early and late production units.
