Will the abnormal noise from a dual-clutch transmission cause damage?
3 Answers
It depends on the specific situation. The details are as follows: 1. Normal condition: If the dual-clutch transmission of the car only makes a slight "click" sound during gear shifting, this is a very normal phenomenon and will not have any impact on the engine or transmission. The reason why this sound mainly occurs in low gears is that the speed difference in low gears is relatively large, and the torque fluctuation during gear shifting is greater than in other gears. 2. Damage condition: If the transmission makes continuous abnormal noises while driving, it is very likely that the transmission gears are slipping. In this case, the owner needs to go to a repair shop for inspection as soon as possible.
I've been driving a dual-clutch car for over ten years, and honestly, when the transmission starts making noise, you need to be alert. It won't break down immediately, but there's an 80% chance something's wrong inside, like the clutch plates wearing thin or issues with the gear shaft. If you don't take it to the repair shop in time, the wear and tear will get worse, and the whole transmission might end up being scrapped. Repairs can be expensive—my neighbor procrastinated last time and ended up spending thousands on a replacement. Also, if the noise is minor, adding some lubricant or tightening a few parts might solve it at a low cost, but delaying until it becomes a major issue isn't worth it. Listening to your car is crucial—safety first. Driving this kind of car requires extra attention.
As an ordinary driver who enjoys tinkering with cars, I must emphasize that dual-clutch abnormal noise doesn't necessarily mean immediate failure, but it's often a precursor to issues like clutch friction plate wear or unstable hydraulic pressure. Ignoring it can lead to bigger problems such as acceleration slippage or transmission disintegration, which not only causes inconvenience but may also lead to traffic accidents. I recommend taking time to visit a repair shop for inspection—don't gamble with luck, as spending a little now is better than facing exorbitant repair costs later. Avoid aggressive throttle inputs during daily driving, and proper maintenance can prevent problems. After all, your car is like an old friend—treat it well.
