ZF 4660.202.001 TURBINE SHAFT for WG200/WG92/WG98 | OEM Genuine Part

Genuine ZF TURBINE SHAFT (Part No. 4660.202.001). This part fits: 4 WG 92, 4 WG 98, 4 WG 98 PS, 6 WG 200(555/3), WG 92 and 2 more models. Found in: Input. Also referenced as: 4660202001 / 4660.202.001 / 4660 202 001.

Overview

The ZF 4660.202.001 Turbine Shaft is a critical rotating component engineered for the WG200, WG92, and WG98 series transmissions. This OEM genuine part transfers torque from the torque converter turbine to the planetary gearset, enabling smooth power delivery under heavy loads. The SKU 4660.202.001 sits directly within the main shaft assembly, interfacing with the 4660198001 PERIPHERALS kit and the 4660101011 TRANSMISSION HOUSING to maintain precise alignment. Manufactured to ZF’s original tolerances, this shaft ensures minimal vibration and maximum durability in industrial drivetrains.

Symptoms of Failure

  • Torque converter shudder or vibration: A worn turbine shaft causes uneven load transfer, leading to noticeable shudder during acceleration.
  • Delayed or harsh gear engagement: When the shaft splines wear, the transmission hesitates before engaging gears, often accompanied by a clunk.
  • Low transmission fluid pressure: Internal leakage around the shaft reduces hydraulic pressure, triggering warning codes or slipping.
  • Metallic debris in oil pan: Flaking or pitting on the shaft surface contaminates the fluid, visible as glitter during oil changes.

Compatibility

This turbine shaft is directly compatible with ZF WG180, WG200, WG92, and WG98 series transmissions. It is also used in select WG120 variants where the torque converter assembly matches the 28 mm spline interface. For proper installation, ensure the 0501209818 RANGE SELECTOR and 4660301018 HOUSING are inspected for wear. The shaft is not backward-compatible with older WG100 series units without adapter modifications.
