2 Answers
SAIC's 6-speed wet dual-clutch transmission malfunction exhibits the following symptoms: 1. Transmission: Transmission oil leakage. 2. Acceleration: The vehicle does not move when accelerating in place. 3. Jerking: Jerking during gear shifting, or jerking when engaging gears. 4. Abnormal noise: Abnormal noise during gear shifting, or noise when engaging gears. 5. Engine: Lack of power during upshifting, high engine RPM, and slow speed increase. 6. Dashboard: Warning lights appear on the dashboard, or a direct transmission fault warning is displayed. Characteristics of dual-clutch transmissions: 1. Fuel efficiency: DSG transmissions improve vehicle fuel economy; 2. Responsiveness: Quick response; 3. The vehicle does not experience power interruption during acceleration, making acceleration stronger and smoother; 4. Manual mode: When manual mode is selected, upshifting is not performed even if the accelerator is fully depressed.
I just bought a Roewe, and it uses this type of transmission. The main symptoms of the malfunction include a sudden jerk when shifting gears, as if the car is being pushed. There might be a clicking noise during acceleration, and sometimes the power cuts out—you press the gas, but the car doesn't move. The fault light on the dashboard may come on, indicating a transmission problem. In severe cases, the car gets stuck in a certain gear and can't shift, making driving very awkward. I once encountered a transmission overheating warning during summer traffic jams, and I could even smell burning inside the car. I immediately stopped to check the coolant to prevent further damage. If you notice these symptoms, it's best not to drive fast and go straight to a professional repair shop. Don't wait as long as I did—half a year—before getting it fixed, or the repair costs will be much higher.
