How often should a car transmission be serviced?
2 Answers
Car transmissions should be serviced every 2 years or 40,000 kilometers. The transmission is located below the gear shift lever and is divided into manual transmissions and automatic transmissions. The functions of the transmission are: 1. To change the transmission ratio and expand the range of torque and speed changes of the driving wheels; 2. To allow the car to reverse while keeping the engine's rotation direction unchanged; 3. To use neutral gear to interrupt power transmission, enabling the engine to start, idle, and facilitating gear shifting or power output. The maintenance methods for the transmission are: 1. Check the oil quality and quantity according to the intervals specified by the manufacturer; 2. Regularly replace the oil with products that meet the manufacturer's specifications; 3. Have the transmission repaired at a professional repair facility.
As a veteran driver with ten years of experience, I can't stress enough how important transmission maintenance is. The differences between various models are significant. Manual transmissions typically require an oil change every 40,000 to 60,000 kilometers, while automatic transmissions generally need servicing every 60,000 to 80,000 kilometers. CVT and dual-clutch transmissions are more delicate, with manufacturers recommending fluid checks every 40,000 to 50,000 kilometers. Since I drive aggressively and often navigate mountain roads, I changed my transmission fluid early at 40,000 kilometers. A friend of mine once delayed maintenance until 80,000 kilometers to save trouble, only to end up with a clogged valve body repair costing over 5,000 yuan. Pay attention to signals like jerky driving or delayed gear shifts, and address any issues early. Lastly, a reminder for those who frequently drive long distances: under harsh road conditions, the maintenance interval should be shortened by about 30%.
