Will the abnormal noise from a dual-clutch transmission cause damage?

[ThomasFitz]

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.
