Overview
The ZF 4460.308.079 SLIDING PAD is a critical wear component engineered for the WG200 series transmission. This OEM genuine part acts as a low-friction interface within the shift mechanism, reducing metal-on-metal contact during gear changes. Positioned directly on the shift rail assembly, the sliding pad ensures smooth axial movement and precise engagement of the clutch packs. The SKU 4460.308.079 is manufactured to ZF’s exacting tolerances, guaranteeing a direct fit and restoring original shift feel. When replacing this pad, it is common 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 4460.308.079 sliding pad deteriorates, operators will notice distinct operational issues. The most common symptom is gear slipping under load, particularly during upshifts, as the pad can no longer maintain proper rail alignment. Another frequent complaint is difficulty engaging reverse gear, often accompanied by a grinding noise. You may also observe intermittent loss of drive in forward gears due to the pad’s inability to hold the shift fork in position. Finally, excessive play in the shift lever at the transmission housing indicates the pad has worn beyond its service limit. These symptoms often prompt replacement of the 0636011429 HEXAGON SCREW and the 0730100365 WASHER during the same repair.
