Does occasional gear grinding during shifting have any impact?

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.

Veteran manual transmission drivers dread nothing more than the dreaded gear grinding sound, which is basically torture for the gearbox. That brief metallic crunch may seem insignificant, but it leaves burrs on gear edges like they've been sanded by a grinding wheel. My buddy's old Bora initially had occasional grinding, but three months later, the reverse gear completely refused to engage - disassembly revealed a chipped reverse gear tooth. This is especially common in winter when cold transmission oil thickens and synchronizers respond sluggishly; forcing gear shifts under these conditions increases grinding risk. Pro tip: depress the clutch pedal past its rebound point with complete commitment, like crushing a soda can. If you notice first gear persistently popping out at stoplights, consider that your synchronizer's distress signal.

Last time I helped my cousin inspect a used car, I noticed a gear grinding sensation when shifting into third gear during the test drive. The mechanic said this is mostly related to driving habits, and female drivers often wearing thick-soled shoes makes it harder to fully depress the clutch. Minor gear grinding sounds scary but isn't a big issue, though it would be troublesome if metal shavings got into the transmission fluid. The mechanic taught me a detection method: with the car stationary, try shifting into reverse without pressing the clutch - if you hear gear collision sounds, it means the clutch isn't fully disengaging. New cars now have anti-grinding designs, but with older cars you need to be more careful. Remember to check the synchronizer when changing transmission fluid at 30,000 km - this preventive maintenance cost is much cheaper than a major repair.

When I first started learning to drive, the instructor yelled 'depress the clutch fully' the most. Gear grinding is essentially caused by the input shaft and output shaft speeds not being synchronized, forcing two rotating gears to clash. Automatic transmission cars have a torque converter to cushion the impact, while manual transmissions rely entirely on the copper friction ring on the synchronizer. Frequent gear grinding wears down the friction ring like an eraser, making gear shifts feel like bending an iron rod. The worst case I've seen in the repair shop was an owner who ground the transmission oil into a metallic paste, requiring the entire differential to be replaced. Don't panic if it happens occasionally, but remember to rev the engine to match the RPMs before shifting, especially when downshifting to overtake.
