Is it normal for a dual-clutch transmission to make a clicking sound when shifting gears?
1 Answers
If the dual-clutch transmission only produces a slight "click" sound during the gear shifting process, then this situation is perfectly normal and will not have any impact on the engine or transmission. The reason this sound mainly occurs in low gears is that the speed difference in the transmission is greater at low gears, and the torque fluctuation during shifting is larger than in other gears. If the transmission makes continuous clicking sounds while driving, it is necessary to have it checked at a repair shop as soon as possible. Explanation of the causes of abnormal sounds in dual-clutch transmissions: 1. Gear pre-engagement: The shift fork drives the shift assembly to quickly engage the synchronizer ring, achieving gear pre-engagement. 2. Dual-clutch working switch: The pre-engaged idling gear begins to bear the load, and the gap between the driving gear and the driven gear gradually decreases until they are fully meshed. During this process, slight metal knocking sounds may occur.
