2 Answers
The causes of abnormal noises when shifting gears are: 1. Improper operation by the driver, applying excessive force; 2. Broken or shattered gears; 3. Malfunction of the gearbox internal mechanism; 4. Damaged internal bearings. The solutions for abnormal noises when shifting gears are: 1. Pay attention to driving habits and avoid applying excessive force when operating the gear lever; 2. Check if the gears are broken or shattered; 3. Inspect whether the gearbox internal mechanism is malfunctioning; 4. Check if the internal bearings are damaged. Precautions for shifting gears include: 1. Do not lower your head to shift gears, pay attention to driving safety; 2. Stabilize the steering wheel when shifting gears, hold the steering wheel firmly with one hand and shift gears with the other; 3. Do not shake the gear lever violently back and forth; 4. The gear and speed should match.
I know all about gear shifting noises! My old car used to make creaking sounds when shifting gears, and it took me forever to figure out the root cause. The most common culprit is the clutch three-piece kit failing. For example, when the release bearing wears out, you'll hear a rattling noise when pressing the clutch. If the pressure plate fingers get deformed, you'll get a loud clunk the moment you engage a gear. When the clutch disc wears thin as paper, the car even shakes during takeoff. Then there's the transmission - if the synchronizer gets stuck or gear teeth get chipped, the gear lever resists and makes a cracking sound when forced. Oh, and if the transmission oil is low or turns black, the internal components grinding dry will also make noise. Some older cars have cracked rubber boots under the gear lever, causing plastic to hit metal directly - now that produces some crisp sounds!
