ZF 2098.306.057 GEARSHIFT FINGER for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2098.306.057 GEARSHIFT FINGER is a precision-machined internal selector component engineered for the WG100, WG130, and WG131 series transmissions. This OEM genuine part, identified by SKU 2098.306.057, sits directly within the shift rail assembly and translates driver input into precise gear engagement. It interfaces with the 2098117002: HOUSING to ensure smooth, positive shifting under heavy-duty loads. Without this finger, the transmission cannot reliably select or hold gears, making it critical for drivetrain integrity.

Symptoms of Failure

• Gear slippage under load: A worn shift finger fails to lock the shift fork, causing the transmission to pop out of gear during acceleration.
• Hard shifting or grinding: When the finger’s contact surfaces wear, you will experience resistance or audible grinding when moving between gears.
• Neutral lockout: The transmission may become stuck in gear or refuse to return to neutral, a common failure mode for fatigued shift fingers.
• Erratic shift pattern: The gear lever may feel loose or require multiple attempts to engage the correct gear, indicating the finger has lost its indexing precision.
