[DiElliot]

Maintenance methods for automatic transmission cars: 1. Regularly check the transmission fluid: The transmission fluid must be replaced after a period of use to ensure its cleanliness for optimal performance; 2. Periodically replace the transmission fluid: If you notice vibrations or delays when shifting gears in an automatic transmission car, it indicates the need to replace the transmission fluid; 3. Ensure the proper amount of transmission fluid: Engine oil should be checked when the engine is cool, while the transmission fluid should be checked when the transmission is preheated to 50 degrees Celsius. After shifting through each gear for 2 seconds and then shifting to park, observe whether the fluid is at the normal level. If it is below the minimum line, promptly add the same quality of lubricating oil.
