What is the replacement interval for automatic transmission fluid in sedans?
1 Answers
Automatic transmission fluid in sedans should be replaced every 120,000 kilometers. The functions of transmission fluid include maintaining the cleanliness of the gear system, providing lubrication, ensuring proper transmission operation, and extending the lifespan of the transmission components. The role of the transmission: to change the gear ratio, expand the range of torque and speed variation for the driving wheels, adapt to frequently changing driving conditions, and allow the engine to operate under favorable conditions. Hazards of not replacing transmission fluid for an extended period: 1. Damage to the transmission's shift control mechanism; 2. Abnormal wear of gears and clutch plates inside the transmission; 3. Impaired transmission operation, leading to damage of the transmission valve body.
