ZF 4644.306.494 GASKET for WG 180/WG 200 | OEM Genuine Part

Overview

The ZF 4644.306.494 Gasket is a precision-engineered sealing component designed specifically for the WG 180 and WG 200 series transmissions. This OEM genuine part sits between the transmission housing and the valve body or cover plate, creating a leak-proof barrier that maintains hydraulic pressure and prevents contamination ingress. The SKU 4644.306.494 is manufactured to ZF’s exacting tolerances, ensuring a perfect fit and long service life. When installed alongside a TRANSMISSION HOUSING, this gasket forms a critical seal that protects internal components from debris and fluid loss.

Symptoms of Failure

• Oil leaks at the housing interface: A worn 4644.306.494 gasket often causes visible transmission fluid drips or wet spots around the mating surfaces, especially after extended operation.
• Erratic gear engagement or slipping: When the gasket fails, hydraulic pressure drops can lead to delayed shifts or clutch slip during acceleration.
• Contaminated transmission fluid: A compromised seal allows dirt and moisture to enter the system, causing dark, gritty fluid and reduced lubrication efficiency.
• Overheating transmission: Loss of fluid pressure from a leaking gasket forces the transmission to work harder, generating excess heat and potential damage to internal parts.

Technical Specifications

Compatibility

This gasket is engineered for ZF WG 180 and WG 200 series transmissions, including the WG 180, WG 200, and WG 65 variants. It is also compatible with select ZF off-highway and industrial transmissions that share the same housing design. Always verify fitment by cross-referencing your transmission model with the SKU 4644.306.494. For secure installation, pair this gasket with HEXAGON SCREW (0636011038), HEXAGON SCREW (0636011118), and HEXAGON SCREW (0636016015) to ensure proper clamping force and sealing integrity.
