ZF 4644.307.013 SPEEDOMETER DRIVE SHAFT for WG200 | OEM Genuine Part

Overview

The ZF 4644.307.013 SPEEDOMETER DRIVE SHAFT is a precision-machined component engineered specifically for the WG 200 Series transmission. This genuine OEM part transmits rotational motion from the output shaft to the speedometer gear assembly, ensuring accurate vehicle speed readings for fleet operators and heavy-duty machinery. Located within the rear housing of the transmission, the SKU 4644.307.013 interfaces directly with the 4460165051: CONSOLE and the 4460368311: CONSOLE to maintain proper alignment and torque transfer. Without this drive shaft, the transmission’s electronic control unit cannot calculate shift timing or road speed, making it a critical link in the drivetrain chain.

Symptoms of Failure

• Erratic or intermittent speedometer needle fluctuation – When the drive shaft splines wear, the gear engagement becomes inconsistent, causing the speedometer to jump or drop unexpectedly during highway operation.
• Complete loss of speed signal – A fractured 4644.307.013 shaft stops all rotation to the sensor, resulting in a “0 mph” reading and triggering a check-engine light for transmission speed faults.
• Oil seepage around the transmission tail housing – Worn shaft bushings or a cracked drive shaft body allow transmission fluid to escape, leaving visible drips under the vehicle and lowering fluid levels.
• Harsh or delayed gear shifts – Without accurate speed data from this shaft, the transmission control module defaults to limp mode, causing jarring upshifts and hesitation during acceleration.

Technical Specifications

Compatibility

This speedometer drive shaft is designed primarily for the ZF WG200 series transmissions, including models WG200, WG200T, and WG200V. It also fits select WG180 variants produced after 2012, where the output housing shares the same spline geometry. The 4644.307.013 is not backward-compatible with older WG150 or Ecomat series units without a housing adapter. For proper installation, always pair this shaft with the 0636011429: HEXAGON SCREW and the 0730100365: WASHER to secure the console assembly. Verify your transmission’s serial number against ZF’s parts catalog before ordering.
