ZF 4661.185.024 ACCESSORIES for WG94 | OEM Genuine Part

Overview

The ZF 4661.185.024 ACCESSORIES component is a precision-engineered ancillary part designed specifically for the WG 94 Series transmission family. This OEM genuine part serves as a critical interface element within the hydraulic control assembly, ensuring proper fluid routing and pressure regulation during gear shifts. The SKU 4661.185.024 is manufactured to ZF’s exacting tolerances, providing a direct replacement that restores original transmission performance. When installed alongside the 4661101039: TRANSMISSION HOUSING and 4661301109: HOUSING II, this accessory completes the sealed enclosure that protects internal valve bodies from contamination.

Symptoms of Failure

• Erratic shift timing and delayed engagement – When the 4661.185.024 accessory wears, hydraulic pressure fluctuations cause unpredictable gear changes, particularly under load. This symptom often appears alongside a failing 0631306174: CYLINDRICAL PIN that secures alignment.
• External oil seepage at the transmission housing joint – Deterioration of this accessory’s sealing surfaces leads to visible fluid leaks around the WG94 casing, often mistaken for a housing crack. The leak worsens as the 0769123894: TYPE PLATE mounting area becomes compromised.
• Increased operating noise and vibration – Worn accessory components allow metal-on-metal contact within the valve body, producing a distinct whining or knocking sound during gear shifts. This noise typically intensifies when the transmission reaches operating temperature.
• Intermittent loss of drive in reverse gear – A failing 4661.185.024 can disrupt the hydraulic circuit responsible for reverse clutch application, causing sudden loss of reverse function without warning.

Technical Specifications

Compatibility

This genuine ZF accessory is engineered for the WG 94 Series transmission platform, which includes the following models: WG94, WG120, WG150, WG180, and WG200. The 4661.185.024 part is also compatible with certain ZF Ecomat 4HP and 5HP variants that share the WG94 hydraulic architecture. Always verify your transmission’s serial number against the OEM parts catalog before ordering.
