Why does the clutch make a clunking sound when shifting from first to second gear?
3 Answers
When shifting from first to second gear in a car, there is a jerking sensation when releasing the clutch. This happens because the clutch is released too quickly. The gear ratio differences between each gear in low-speed gears are relatively large, while in high-speed gears the differences are smaller and less noticeable. The reasons for the clunking sound when shifting from first to second gear while pressing the clutch are as follows: Releasing the throttle too early: Lifting the throttle before pressing the clutch when shifting. The engine jerks. When shifting in low gears (especially from first to second), the throttle and clutch must be well-coordinated to ensure smooth driving. Releasing the throttle too late: If the clutch is pressed but the throttle is not lifted in time during shifting, the car will accelerate momentarily during the semi-clutch phase, and there will be a jerking sensation when the power is completely disconnected after full separation.
I'm a new driver who just got my license. Recently, every time I shift from first to second gear and press the clutch, I hear a 'clunking' noise, and it feels like the car is shaking, which is quite scary. I consulted several experienced friends who've been driving for years, and they told me it's mostly likely due to worn clutch plates or a loose pressure plate, especially common in older cars where parts have aged. If left untreated, the noise will get worse, shifting will become more difficult, and it might even damage other parts of the transmission. They suggested I go to a nearby repair shop for inspection immediately. The mechanics there can diagnose the issue with professional equipment, and minor problems can be fixed for just a few hundred yuan. When shifting gears normally, I should be decisive yet gentle with my movements, avoiding forcing the gear at high speeds to reduce component friction. Regular maintenance checks on the clutch system can also help prevent this issue from occurring.
I've had quite a few experiences with car repairs. When shifting from first to second gear, the clutch makes a 'clunking' sound, which is often caused by wear on the clutch release bearing or deformation of the pressure plate. The release bearing is mainly responsible for pushing the pressure plate. If it fails, the pressure plate cannot fully disengage, causing the friction disc and pressure plate to collide and create noise. Over time, the flywheel may also be damaged. It's difficult to inspect this yourself, so I recommend driving to a professional shop for a check-up. The cost is usually just a few hundred dollars. If you notice significant abnormal noises while driving, stop the car promptly and check if the clutch pedal feels unusually heavy. For routine maintenance, have a mechanic check the clutch fluid level and component condition every 40,000 kilometers or so to prevent issues and ensure smooth, safe gear shifting.
