What is the issue with noise when driving a dry dual-clutch transmission?

[DeLorenzo]

Dry dual-clutch transmission noise primarily occurs during gear shifts due to the operation of the shift fork. The dry clutch is a manual friction plate clutch with low manufacturing costs and high mechanical transmission efficiency. However, it requires precise operation, is relatively cumbersome to use, and has a high failure rate. Below is more relevant information: 1. Dry Dual-Clutch Transmission: By eliminating the hydraulic system, dry dual-clutch transmissions offer advantages in manufacturing cost, weight reduction, and space optimization. Additionally, the absence of hydraulic resistance results in higher transmission efficiency and better fuel economy compared to wet clutches. 2. Dual-Clutch Transmission: Dual-clutch transmissions are not suitable for frequent starts, prolonged low-speed driving, or stop-and-go traffic, as these conditions can lead to overheating and potential failures. If the vehicle computer issues a warning, the driver must immediately stop and allow the transmission to cool. In unavoidable traffic congestion, it is advisable to use lower gears (manual mode or S mode) to minimize excessive clutch heat caused by frequent gear changes.

My car has a dry dual-clutch transmission, and recently it keeps making clicking noises while driving, which is really annoying. This situation is mostly caused by worn clutch plates. The dry structure is particularly susceptible to the effects of city traffic congestion, with frequent starts and stops causing the friction plates to wear out prematurely. Alternatively, there might be an issue with the hydraulic control system, such as clogged oil passages or leaks, leading to insufficient pressure and improper engagement. Additionally, electronic module failures could also trigger noises, like sensor signal deviations causing imprecise clutch actions. The noise becomes even more noticeable when I drive on the highway, making it impossible to ignore. It's best to take it to a professional repair shop for diagnosis as soon as possible. They can use a computer to check for error codes, and replacing a small component might only cost a few hundred dollars. Don't delay until you have to replace the entire transmission, which would cost more and disrupt your travel plans.

The dry dual-clutch transmission is making abnormal noises, sounding like metal grinding, which really creeps me out. This could indicate excessive wear on the clutch or a failure in the hydraulic system. If you continue driving, you might experience sudden jerks or even stalling, which is extremely dangerous on the highway. I once had a similar experience and nearly got into an accident, so I immediately pulled over and didn’t take the risk. The noise isn’t a minor issue—it’s mostly caused by wear leading to increased gaps or fluid leaks, which can easily spread and damage the entire transmission, costing tens of thousands in repairs. I recommend checking the transmission fluid and temperature status to ensure your family’s safety. Head to the 4S shop for a comprehensive test immediately—don’t save a little money now only to lose big later.

My dual-clutch car often makes a slight clicking noise when driving in the city. I asked a mechanic, who said it's related to driving habits. The dry-type structure is sensitive to the semi-clutch state, and frequent braking and accelerating in traffic jams can accelerate clutch plate wear, leading to abnormal sounds. After changing my driving style by anticipating road conditions in advance to reduce sudden stops, the noise lessened. Regular maintenance is also crucial; inspecting the clutch system every two years can extend its lifespan. Maintaining smooth driving is much more cost-effective than repairs.
