ZF 4166.028.094 CONVERTER Torque Converter Assembly | Complete Unit

Overview

The ZF 4166.028.094 CONVERTER Torque Converter Assembly is a critical hydraulic component responsible for transferring engine torque to the transmission input shaft within the WG 100 Series. This complete unit acts as a fluid coupling, multiplying torque during initial acceleration and providing smooth power delivery. The SKU 4166.028.094 is designed to replace worn or damaged converters, restoring full driveline efficiency. It sits directly between the engine flexplate and the transmission pump, housed within the 4651101009: TRANSMISSION HOUSING, and works in conjunction with the 4651301025: HOUSING to maintain proper alignment and fluid sealing.

Symptoms of Failure

• Shuddering or vibration during acceleration: A failing torque converter often causes noticeable shuddering, especially when climbing hills or under load, as the internal lock-up clutch begins to slip.
• Transmission overheating and fluid discoloration: Worn internal bearings or stator clutch failure generate excessive heat, turning transmission fluid dark brown or burnt-smelling.
• Delayed or harsh gear engagement: When the converter fails to maintain hydraulic pressure, you may experience a pronounced lag when shifting from Park to Drive or Reverse.
• Whining or grinding noises from the bell housing: Mechanical wear inside the 4166.028.094 unit produces audible whining or grinding sounds that intensify with engine RPM.

Technical Specifications

Compatibility

This torque converter assembly is engineered for the ZF WG 100 Series, including models such as the WG180, WG200, and WG210. It is also compatible with certain WG150 and WG160 variants that share the same bell housing pattern. The unit mounts directly to the 4651301031: HOUSING and requires proper alignment with the transmission pump drive tangs. Always verify the spline count and pilot diameter against your specific transmission model before installation.
