Overview
The ZF 4460.308.385 SLIDING PAD is a critical wear component engineered for the WG200 series transmission. This OEM genuine part acts as a low-friction interface between the shift fork and the sliding sleeve, ensuring precise gear engagement and smooth power transfer within the transmission assembly. The SKU 4460.308.385 is specifically designed to absorb axial loads and reduce metal-on-metal contact, preventing premature damage to the shift mechanism. Positioned directly on the shift rail system, this sliding pad maintains consistent alignment during high-torque operations, making it essential for maintaining the operational integrity of your ZF drivetrain.
Symptoms of Failure
- Hard shifting or gear engagement difficulty: When the 4460.308.385 sliding pad wears down, operators often experience resistance when moving the gear selector, particularly in low-range or reverse gears.
- Audible grinding or clicking noises from the transmission housing: A worn pad creates excessive clearance between the shift fork and sleeve, producing metallic sounds during gear changes under load.
- Intermittent gear slipping under heavy load: As the pad loses its dimensional integrity, the shift fork cannot fully lock the sliding sleeve, causing unexpected disengagement during acceleration or hill climbing.
- Increased transmission oil contamination: Abraded pad material can circulate through the hydraulic system, clogging valve bodies and accelerating wear on adjacent components like the 4460165051: CONSOLE and 4460368311: CONSOLE.

Compatibility
This sliding pad is primarily designed for the ZF WG200 series transmissions, including the WG200, WG180, and WG150 variants. It is also compatible with select ZF Ecomat 4HP and 5HP series where the shift fork geometry matches the WG200 platform. The 4460.308.385 part is a direct replacement for original equipment in ZF off-highway and commercial vehicle transmissions manufactured between 2005 and 2020. Always verify shift rail diameter (typically 16mm) before installation.
