Does occasional gear grinding during shifting have any impact?
2 Answers
Occasional gear grinding during shifting does not have any impact. Here is the relevant content introduction: 1. Manual transmission: A manual transmission is a structurally simple, reliable, and durable type of transmission, with all internal components being gears. The control mechanism of a manual transmission consists of the gear lever, shift fork, and synchronizer. 2. Precautions: When shifting gears in a manual transmission car, it is essential to depress the clutch pedal quickly and fully to ensure smooth gear changes. When engaging the reverse gear, since the reverse gear does not have a synchronizer, some unusual noises may occur after engaging the reverse gear. This is the sound of the reverse gear meshing, which is a normal phenomenon. When using a manual transmission, it is important to change the transmission oil regularly. Generally, a manual transmission requires transmission oil replacement every 100,000 kilometers.
That day at the repair shop, I happened to meet an owner with a similar situation. Talking about gear grinding, this really can't be taken lightly. If you rush to shift gears without fully depressing the clutch, the gears clash hard, making that 'click' sound—it's heartbreaking to hear. The key issue is that doing this repeatedly wears out the friction material on the synchronizer ring, making shifting increasingly rough. Even worse is the release bearing; the impact from rapidly depressing the clutch for shifting can cause it to fail prematurely. I once worked on an 80,000-kilometer manual Ford Focus where the owner always liked to shift gears while half-engaging the clutch. When we took it apart, we found the shift fork was deformed. If you notice gear grinding becoming more frequent, I recommend checking the clutch three-piece set early to avoid having to shift gears like bending rebar later on.
