Overview
The ZF 4460.308.085 SLIDING PAD is a critical wear component engineered specifically for the WG 200 Series transmission. This OEM genuine part functions as a low-friction interface within the clutch or shift mechanism, reducing metal-on-metal contact during gear engagement. Positioned inside the transmission housing, the sliding pad ensures smooth axial movement of the synchronizer assembly. The SKU 4460.308.085 is precision-molded to ZF’s original tolerances, guaranteeing a direct fit without modification. When paired with a properly torqued 0636011429 HEXAGON SCREW and a 0730100365 WASHER, this pad maintains consistent pressure on the shifting fork, preventing premature wear on adjacent components like the 4460165051 CONSOLE or the 4460368311 CONSOLE.
Symptoms of Failure
- Hard shifting or gear grinding: A worn sliding pad loses its smooth surface, causing the shift fork to bind. This often manifests as a “sticky” feel when moving between gears, especially in cold oil conditions.
- Unusual metallic rattling from the transmission: When the pad thickness degrades below specification, the fork develops lateral play, producing a distinct rattle at idle or during deceleration.
- Intermittent gear disengagement: A severely worn pad cannot hold the synchronizer in position, leading to the transmission “popping out” of gear under load, particularly in second or reverse.
- Oil contamination with fine metallic particles: As the pad erodes, microscopic debris enters the transmission fluid, accelerating wear on bearings and seals. This symptom is often detected during routine oil analysis.

Compatibility
This sliding pad is a direct replacement for the following ZF transmission models: WG180, WG200, and WG210 series. It is also compatible with select variants of the Ecomat 4HP and 6HP families that share the same shift fork geometry. Always verify the part number 4460.308.085 against your transmission’s serial plate before installation. For complete rebuilds, consider inspecting the 4644105418 DISCONNECTION and 4644305041 ADAPTER for simultaneous wear.
