Overview
The ZF 4460.308.487 SLIDING PAD is a critical wear component engineered for the WG 200 Series transmission. Positioned within the clutch pack assembly, this OEM genuine part acts as a low-friction interface, reducing metal-to-metal contact during gear shifts. The SKU 4460.308.487 ensures precise alignment and smooth axial movement of the sliding sleeve, directly influencing shift quality and torque transfer efficiency. Without this pad, the transmission’s hydraulic actuation system cannot maintain consistent pressure, leading to premature component fatigue.
Symptoms of Failure
- Delayed or harsh gear engagement – A worn sliding pad causes erratic clutch pack compression, resulting in noticeable “clunking” when shifting from neutral to drive.
- Intermittent gear slipping under load – As the pad loses its surface integrity, the transmission may momentarily lose torque transfer during uphill climbs or heavy towing.
- Metallic grinding noise from the bell housing – Degraded pad material allows steel-on-steel contact, producing a distinct high-pitched whine or grinding sound during acceleration.
- Hydraulic fluid contamination – Fragments from a disintegrating pad can circulate through the valve body, clogging solenoids and accelerating wear on adjacent components.

Compatibility
This sliding pad is specifically engineered for the ZF WG 200 Series, including models WG180, WG200, and WG210. It is also compatible with select ZF Ecomat 4HP and 5HP variants that share the same clutch pack architecture. Always verify your transmission’s serial number against the OEM parts catalog before installation. For proper assembly, this pad must be paired with the 4460165051: CONSOLE and 4460368311: CONSOLE to maintain correct axial clearance. Secure the assembly using the 0636011429: HEXAGON SCREW and 0730100365: WASHER to prevent loosening under vibration.
