Overview
The ZF 4460.308.489 SLIDING PAD is a critical wear component engineered specifically for the WG200 series transmission. This OEM genuine part functions as a low-friction interface within the shift mechanism, reducing metal-on-metal contact during gear changes. Positioned inside the transmission housing, the sliding pad ensures smooth axial movement of the shift fork, directly influencing shift quality and clutch engagement. The SKU 4460.308.489 is precision-molded to ZF’s original tolerances, guaranteeing a direct fit without modification. When replacing this pad, it is standard practice to also inspect the 4460165051: CONSOLE and the 4460368311: CONSOLE for wear, as these components share the same load-bearing assembly.
Symptoms of Failure
When the ZF 4460.308.489 sliding pad deteriorates, operators typically notice these specific failure modes:
- Erratic gear engagement or “gear hunting” – The worn pad creates excessive play in the shift fork, causing the transmission to struggle finding or holding a gear under load.
- Metallic grinding noise during shifting – As the polymer pad wears down, metal components begin contacting each other, producing a distinct grinding sound, especially in lower gears.
- Increased shift lever vibration – A worn sliding pad fails to dampen fork movement, transmitting vibration directly to the shift lever or electronic actuator.
- Oil contamination with plastic debris – Advanced wear sheds polymer particles into the transmission fluid, which can clog filters and accelerate damage to other components like the 0636011429: HEXAGON SCREW and 0730100365: WASHER assemblies.

Compatibility
This sliding pad is primarily designed for the ZF WG200 series transmissions, including models WG180, WG200, and WG210. It is also compatible with select ZF off-highway and marine transmissions that utilize the same shift fork architecture. The part directly replaces OEM number 4460.308.489 and is not interchangeable with earlier WG series pads without verifying the shift rail diameter. For complete assembly verification, always cross-reference the 4460165051: CONSOLE and 4460368311: CONSOLE mounting points.
