D+- in automatic transmission refers to the manual mode of an automatic gearbox. An automatic transmission is a gear-shifting device that automatically changes gears based on the vehicle's speed and engine RPM, as opposed to a manual transmission. It can be categorized into: MT automatic transmission, AMT automatic transmission, AT automatic transmission, CVT automatic transmission, and DSG automatic transmission. The maintenance methods for automatic transmissions include: 1. Regularly inspect and replace the specified transmission fluid as per the manufacturer's requirements; 2. Only about 30% of the total fluid can be drained through the drain bolt, and transmission cleaners should not be used; 3. For a complete transmission fluid change, use a transmission cleaner in conjunction with a transmission fluid exchange machine.
