Does the Dual-Clutch Transmission Experience Gear Shift Jerks?
2 Answers
The dual-clutch transmission may exhibit jerky gear shifts during low-speed driving, but the shift jerks become less noticeable at higher speeds. Below is an introduction to the dual-clutch transmission:1. The dual-clutch transmission uses one clutch to control odd-numbered gears and another clutch to control even-numbered gears, enabling very rapid gear shifts.2. The structure of the dual-clutch transmission is not significantly different from that of a manual transmission, except that it has an additional clutch and a set of gear shift control mechanisms.3. The production and development costs of the dual-clutch transmission are relatively low.4. There are two types of dual-clutch transmissions: dry and wet. In the dry dual-clutch transmission, the clutch plates are not immersed in transmission oil.
The car I drive has a dual-clutch transmission, and I sometimes feel jerky shifts during low-speed city driving, especially in stop-and-go traffic or when accelerating too quickly—the car suddenly jerks, which is quite annoying. But on the highway, it’s very smooth, with fast shifts and good fuel efficiency. This is mainly because the dual-clutch has two sets of clutches, and if the RPM isn’t synchronized well during low-speed gear changes, it can easily lead to hesitation. Here’s how I often deal with similar issues: try to press the accelerator smoothly while driving, avoiding sudden inputs; during regular maintenance, have the technician check the transmission software and fluid—sometimes an ECU update can improve performance. Don’t worry, it’s not a major malfunction; most models are designed this way, so you’ll get used to it. It doesn’t affect daily use, though it may not be as smooth as some CVT transmissions in terms of comfort. Overall, jerking is common but doesn’t happen every time—the key lies in driving habits and road conditions.
