ZF 4642.102.070 INPUT for WG150 | OEM Genuine Part

Overview

The ZF 4642.102.070 INPUT for WG150 is a precision-engineered input shaft assembly that serves as the primary torque-transfer interface between the engine and the transmission gearset. As an OEM genuine part, SKU 4642.102.070 is designed to fit seamlessly within the WG 150 Series, ensuring optimal power delivery and alignment. This component sits at the front of the transmission housing, directly engaging the torque converter and planetary gear sets. For a complete rebuild, pairing this input shaft with a new TRANSMISSION HOUSING (4642101047) is recommended to maintain structural integrity, while the TYPE PLATE (0730365067) should be affixed for accurate identification during service.

Symptoms of Failure

• Delayed or harsh engagement – When the input shaft splines wear, you may experience a noticeable lag or clunk when shifting from neutral to drive, a common long-tail search query for “ZF WG150 input shaft failure symptoms.”
• Transmission fluid leaks at the front seal – A worn input shaft can damage the front pump seal, leading to oil puddling under the bell housing. This is often searched as “ZF transmission front seal leak WG150.”
• Vibration during acceleration – Excessive play in the input bearing causes driveline shudder, especially under load, which is frequently reported as “ZF WG150 vibration when accelerating.”
• Gear slipping or erratic shifting – As the input shaft loses its precise fit with the clutch drum, you may notice random slipping in forward gears, a symptom often tied to “ZF WG150 gear slipping repair.”

Technical Specifications

Compatibility

This input shaft is specifically engineered for the ZF WG 150 Series transmissions. It is also compatible with the following ZF models that share the same input architecture: WG180, WG200, and WG120 (when used with the appropriate adapter housing). For installations involving a TRANSMISSION HOUSING (4642301207), verify the bell housing bolt pattern matches. Additionally, secure the assembly using a GROOVED STUD (0631311009) to prevent axial movement during high-torque operations.
