Overview
The ZF 4644.130.413 ENGINE CONNECTION is a critical OEM genuine interface component designed for the WG150, WG200, and WG201 series transmissions. This part serves as the primary mechanical link between the engine flywheel housing and the transmission bell housing, ensuring precise alignment and torque transfer. The SKU 4644.130.413 is manufactured to ZF’s exacting tolerances, providing a sealed connection that prevents contamination ingress and maintains driveline integrity. It sits directly at the input section of the transmission assembly, where it mates with the 4642101109: TRANSMISSION HOUSING and the 4642301205: TRANSMISSION HOUSING to form a rigid structural unit.
Symptoms of Failure
When the 4644.130.413 ENGINE CONNECTION begins to wear, operators often notice specific performance degradation. Oil seepage at the engine-transmission interface is a primary indicator, as the gasket surface loses its sealing capacity. Abnormal driveline vibration during acceleration occurs when the connection develops play, causing misalignment between the engine and transmission shafts. Intermittent gear engagement hesitation can result from flexing at the connection point, which disrupts hydraulic pressure in the shift system. Metallic debris in the transmission oil pan may appear if the connection cracks, allowing fretting wear particles to circulate through the 4642301168: SCREEN SHEET filter media.

Compatibility
This ENGINE CONNECTION is engineered for the ZF WG150, WG200, and WG201 transmission families. It directly replaces the factory-installed unit on WG180, WG190, WG200, and WG201 models produced after 2015. The part is also compatible with earlier WG150 variants when used alongside the 0631311009: GROOVED STUD kit for proper torque retention. For identification purposes, the 0730365125: TYPE PLATE should be consulted to verify the exact transmission series before installation. The connection interfaces with the 4644106300: SHIFT SYSTEM and the 4644306500: COVER PLATE to complete the front-end assembly.
