How to Solve the Jerking Sensation of Dual-Clutch Transmission?
2 Answers
The solutions for the jerking sensation of dual-clutch transmission are: 1. Start the car in P gear: The viscosity of dual-clutch transmission oil is relatively high. If started in N gear, the clutch will receive higher drag torque, causing the vehicle to move slowly. 2. After the engine starts, you can shift and drive without warming up the car: If the road is clear, you can accelerate immediately to allow the transmission to shift into higher gears faster. Dry dual-clutch transmissions rely on air cooling for heat dissipation, which is poor at low speeds but better at high speeds. 3. Dual-clutch transmissions "shift up quickly but shift down slowly": When driving such models, acceleration and deceleration must be very clear to give the transmission clear shift signals.
I've explored quite a few experiences in solving dual-clutch jerking issues, especially since my car has a DSG transmission that often feels jerky during low-speed acceleration. The most effective method is to first perform a transmission software upgrade—many manufacturers' update packages can optimize shift logic and significantly reduce jerking. If that doesn't work, it's necessary to check whether the clutch assembly is worn or needs replacement—a common issue in older cars. Additionally, driving habits matter a lot. I’ve developed the habit of pressing the throttle smoothly when starting, avoiding sudden acceleration or frequent half-clutch engagement, which helps the system adapt smoothly. The cleanliness of transmission fluid shouldn’t be overlooked either; changing it every 60,000 kilometers can prevent many issues. Even for short trips, don’t forget to warm up the car for two minutes to let the lubrication system work properly. Overall, minor issues can be DIY-adjusted, but for serious cases, it’s best to visit a 4S shop for diagnostics—don’t cut corners and risk bigger problems.
