ZF 4642.102.086 INPUT for WG150 | OEM Genuine Part

Overview

The ZF 4642.102.086 INPUT for WG150 is a critical driveline component engineered to transfer rotational force from the torque converter directly into the planetary gear sets of the WG 150 Series transmission. As an OEM genuine part, this input shaft assembly ensures precise alignment and minimal power loss during high-torque operations. The SKU 4642.102.086 interfaces directly with the TRANSMISSION HOUSING and the TRANSMISSION HOUSING to form the primary load-bearing structure of the gearbox. Without this component, the transmission cannot engage forward or reverse gears, making it a non-negotiable element for any rebuild or repair of the WG150 series.

Symptoms of Failure

• Transmission gear slipping under load — When the input shaft splines wear, the clutch packs lose positive engagement, causing the transmission to slip during acceleration or hill climbs.
• Torque converter shudder or vibration — A worn 4642.102.086 input can create axial play, leading to noticeable vibrations at the torque converter housing, especially at low RPM.
• Oil leaks at the bell housing interface — Deterioration of the input shaft seal surface allows transmission fluid to escape, often pooling near the TYPE PLATE area.
• Metallic debris in the transmission pan — Flaking metal from the input shaft splines contaminates the hydraulic system, often requiring replacement of the GROOVED STUD and associated filters.

Technical Specifications

Compatibility

This genuine ZF input shaft is primarily designed for the WG 150 Series transmission. It is also compatible with the following ZF models when used with the correct housing assembly: WG180, WG200, and select variants of the WG120 series. Always verify the spline count and pilot bearing diameter against your existing unit. For a complete rebuild, consider pairing this input with the SHIFT SYSTEM and COVER PLATE to ensure proper hydraulic circuit sealing.
