ZF 4616.307.002 SPEEDOMETER DRIVE SHAFT for WG65 | OEM Genuine Part

Overview

The ZF 4616.307.002 SPEEDOMETER DRIVE SHAFT is a precision-machined component engineered specifically for the WG 65 Series transmission family. This genuine OEM part transmits rotational motion from the output shaft to the speedometer sensor, ensuring accurate vehicle speed readings for fleet management and diagnostics. The SKU 4616.307.002 sits within the rear housing assembly, directly engaging with the 4616101059 TRANSMISSION HOUSING to maintain proper alignment and sealing. Without this drive shaft, the transmission cannot relay speed data to the ECU or dashboard.

Symptoms of Failure

• Erratic or intermittent speedometer readings – A worn drive shaft causes the speed sensor to lose contact, resulting in fluctuating needle movement or zero readings at highway speeds.
• Oil seepage near the speedometer drive port – Degraded shaft seals allow transmission fluid to leak past the housing, often leaving puddles under the vehicle after extended operation.
• Grinding or clicking noises from the transmission tail section – Worn gear teeth on the drive shaft produce audible metallic sounds during deceleration or coasting.
• Check engine or transmission warning lights – Modern control modules detect missing speed signals, triggering fault codes that may limit shift quality or lock the transmission in limp mode.

Technical Specifications

Compatibility

This speedometer drive shaft is engineered for the ZF WG 65 Series, but it also fits select models in the WG180, WG200, and WG210 families when used with the correct 0631306085 CYLINDRICAL PIN for alignment. Always verify housing bore dimensions; the shaft is designed for transmissions with a 22.4 mm drive gear pocket. It is not compatible with Ecomat or Ecolife series without adapter kits. For WG65 rebuilds, pair this shaft with a new 0636304019 SCREW PLUG and 0732611049 FILTER INSERT to ensure proper lubrication flow.
