Overview
The ZF 4166.041.013 CONVERTER Torque Converter Assembly is a critical hydraulic coupling component designed for the WG 65 Series transmission family. This complete unit transfers engine torque to the transmission input shaft while providing torque multiplication during launch and lock-up for highway efficiency. The SKU 4166.041.013 sits between the flexplate and the transmission housing, acting as the primary power transfer interface. It integrates seamlessly with the 4616000220: 4 WG 65 assembly, ensuring smooth engagement and minimal power loss in heavy-duty industrial applications.
Symptoms of Failure
- Torque converter shudder or vibration during acceleration – Worn internal clutch plates or damaged stator bearings cause noticeable shuddering, especially under load, indicating the 4166.041.013 unit requires replacement.
- Transmission overheating and fluid discoloration – A failing torque converter generates excessive heat due to internal slippage, leading to burnt-smelling, dark transmission fluid and potential damage to the 4616101101: TRANSMISSION HOUSING.
- Delayed or harsh engagement when shifting from Park to Drive – Internal wear in the converter’s one-way clutch or impeller hub causes a noticeable lag or thud during gear engagement.
- Whining or grinding noise from the bell housing area – Damaged bearings or worn turbine splines produce a high-pitched whine that increases with engine RPM, signaling imminent converter failure.

Compatibility
This torque converter assembly is engineered for the ZF WG 65 Series, specifically the WG180, WG200, and WG210 transmission models commonly found in off-highway trucks, wheel loaders, and industrial material handlers. It directly replaces the original converter in the 4616301304: HOUSING assembly. For proper installation, always pair the 4166.041.013 with new sealing components and fasteners to prevent leaks and ensure correct alignment with the transmission pump.
