Overview
The ZF 4460.308.494 SLIDING PAD is a critical wear component engineered specifically for the WG200 series transmission. This OEM genuine part functions as a low-friction interface between the shifting fork and the synchronizer sleeve, ensuring smooth gear engagement and precise axial movement within the transmission housing. The SKU 4460.308.494 is manufactured to ZF’s exacting tolerances, providing consistent lubrication retention and reducing metal-on-metal contact during load shifts. Positioned directly on the shift rail assembly, this sliding pad works in concert with the 4460165051 CONSOLE and 4460368311 CONSOLE to maintain proper fork alignment. Without this pad, the transmission’s shift quality degrades rapidly, leading to premature wear on adjacent components.
Symptoms of Failure
- Hard shifting or gear grinding – When the sliding pad wears thin, the shift fork loses its precise positioning, causing gears to clash during engagement. This is a common long-tail search query for “ZF WG200 hard shifting causes.”
- Oil contamination with metallic debris – A degraded pad sheds polymer or composite particles into the transmission fluid, visible during drain intervals. Search for “transmission oil metallic particles ZF” often leads to this part.
- Intermittent gear slip under load – As the pad’s surface becomes uneven, the synchronizer cannot fully lock the gear, resulting in momentary power loss. This symptom is frequently searched as “WG200 gear slipping under acceleration.”
- Abnormal shift fork noise – A clicking or scraping sound from the transmission housing during gear changes indicates the pad has worn beyond its service limit.

Compatibility
This sliding pad is primarily designed for the ZF WG200 series transmissions, including the WG200, WG180, and WG160 variants used in medium-duty commercial vehicles and off-highway equipment. It is also compatible with certain ZF Ecolife and AS Tronic models that share the same shift rail architecture. For proper installation, the pad must be paired with the 0636011429 HEXAGON SCREW and 0730100365 WASHER to secure the console assembly. Always verify your transmission model code against the OEM parts catalog before ordering.
