What are the symptoms of a malfunction in SAIC's 6-speed wet dual-clutch transmission?
4 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.
As someone who frequently repairs cars, I've encountered numerous dual-clutch issues. The common symptoms of this wet-type transmission failure include abnormally rough gear shifts with strong jerking sensations, especially noticeable as the car lurches during low-speed driving. A harsh metallic grinding noise can be heard during acceleration. Power transmission interruptions are also prevalent - you may stomp the accelerator but the car won't move, only resuming normal operation after several seconds. Overheating transmission fluid triggering warning lights serves as a critical indicator. Some vehicles experience starting difficulties or gear jams requiring tow truck assistance. I recommend car owners regularly inspect transmission fluid quality and promptly replace worn components to prevent minor issues from escalating.
The most sensitive part of my car is the transmission. Symptoms include noticeable jerking during gear shifts, unsteady acceleration, and especially noticeable shaking when exceeding 60 km/h. Sometimes the engine noise increases, accompanied by clunking sounds. Sudden loss of power is very common, such as during critical overtaking moments when the car loses power and requires pulling over to restart. A warning light on the dashboard indicates an issue. These problems become more pronounced during long-distance driving, with the transmission potentially overheating and shutting down. Regular maintenance, such as checking fluid levels, can help mitigate these issues.
