ZF 4644.130.243 ENGINE CONNECTION for WG200 | OEM Genuine Part

Overview

The ZF 4644.130.243 ENGINE CONNECTION is a critical OEM genuine interface component designed specifically for the WG 200 Series transmission. This part serves as the mechanical link between the engine flywheel housing and the transmission bell housing, ensuring precise alignment and secure torque transfer during operation. As an original ZF-manufactured unit, the SKU 4644.130.243 guarantees exact fitment and durability under high-load industrial conditions. Without this connection, the transmission cannot properly mate to the engine, leading to driveline instability and premature wear on adjacent assemblies.

Symptoms of Failure

• Oil leaks at the engine-transmission interface: When the ENGINE CONNECTION degrades, hydraulic fluid can escape from the mating surface, leaving visible puddles under the vehicle.
• Gear slipping under load: A worn connection causes misalignment, resulting in intermittent power loss or harsh engagement during acceleration.
• Vibration or knocking from the bell housing area: Loose fitment generates audible metallic sounds, especially when shifting between forward and reverse gears.
• Difficulty in transmission removal or installation: Warped or cracked connection points make service procedures excessively difficult, often requiring forced disassembly.

Technical Specifications

Compatibility

This ENGINE CONNECTION is engineered for the ZF WG 200 Series transmissions, including models such as WG180, WG200, and WG210. It is also compatible with select variants of the ZF Ecomat 4HP and 5HP series when used with the appropriate adapter kit. Always verify your transmission model number before ordering. For complete assembly, this part works in tandem with the 4644105417 DISCONNECTION and either the 4644303547 OUTPUT FLANGE or the 4644303012 OUTPUT FLANGE, depending on your driveline configuration. The 4644101121 TRANSMISSION HOUSING provides the structural base for this connection.
