It’s a critical part of the synchronizer assembly that slides on the hub to engage and disengage gears smoothly. Over time the sliding clutch wears, causing hard shifting or gear clash, so it’s commonly replaced during a transmission rebuild or synchronizer overhaul. This specific part uses a big‑pin design and is intended for use with the EF25280 synchronizer.
