ZF 4642.102.069 INPUT for WG150 | OEM Genuine Part

Overview

The ZF 4642.102.069 INPUT for WG150 is a critical OEM genuine component engineered to transfer rotational force from the torque converter directly into the planetary gearset of your ZF WG series transmission. This input shaft assembly, identified by SKU 4642.102.069, sits at the front of the main housing and interfaces directly with the TRANSMISSION HOUSING (4642101109) to ensure precise alignment and load distribution. As a wear-sensitive part, it absorbs constant torsional stress during every shift cycle, making its structural integrity essential for maintaining hydraulic pressure and gear engagement within the WG 150 Series.

Symptoms of Failure

• Delayed or harsh engagement – When the input shaft splines wear, you may notice a pronounced lag when shifting from neutral to drive, often accompanied by a metallic clunk.
• Transmission fluid leaks at the bell housing – A worn input shaft seal surface allows ATF to seep past, leaving visible drips under the vehicle and reducing hydraulic pressure.
• Vibration during acceleration – Excessive play in the input bearing causes driveline shudder, particularly under load between 30-50 mph.
• Intermittent gear slipping – As the shaft loses concentricity, the clutch packs fail to fully engage, resulting in RPM flare without corresponding speed increase.

Technical Specifications

Compatibility

This input shaft is primarily designed for the ZF WG150 series, but it also fits select variants of the WG180 and WG200 transmissions manufactured between 2005 and 2018. Always verify your transmission model tag before ordering; the TYPE PLATE (0730365125) provides the exact series designation. For proper installation, ensure the TRANSMISSION HOUSING (4642301205) is free of burrs and that the GROOVED STUD (0631311009) is torqued to factory specifications to prevent axial movement.
