What are the common faults of the Geely Vision S1 CVT transmission?
2 Answers
Common faults of the Geely Vision S1 CVT transmission include: Shuddering and abnormal noises during acceleration: The main causes of shuddering and abnormal noises due to abnormal oil pressure include: insufficient or excessive oil pressure leading to chain damage or slippage; malfunction in the engagement and release of the lock-up clutch due to abnormal lock-up circuit pressure in the torque converter; and faulty engagement and release of the forward clutch due to abnormal oil pressure. Engine speed fluctuation at idle or stalling when shifting into gear: In this case, it is necessary to check the oil pressure of the forward clutch, the flow rate of the radiator, and the engagement and release oil pressure of the lock-up clutch. Torque converter fails to lock up: This is related to the lock-up circuit of the torque converter, requiring inspection of the lock-up oil pressure and lock-up release oil pressure.
I've encountered several issues with the Geely Vision S1 CVT transmission during driving, the most common being chain slippage. When accelerating, the engine roars but the car speed doesn't increase, which is as annoying as idling. Once on the highway, the transmission jerked severely and I almost rear-ended another car. It turned out to be a short circuit in the control module upon inspection. Sensors are also prone to failure; for example, a faulty oil temperature sensor can cause delayed gear shifting. Insufficient or leaking transmission fluid is another hidden danger, especially in older cars with aging oil pipes. Ignoring these problems can lead to repair costs running into thousands and affect driving safety. It's recommended to change the specialized fluid every 20,000 kilometers and get timely diagnostics at the 4S shop. Never delay repairs until the transmission breaks down on the road—that's far too dangerous.
