Is it necessary to change the Aisin 6AT transmission fluid every three years?
1 Answers
Aisin 6AT transmission fluid is generally replaced every 3 years or approximately 60,000 kilometers. If the vehicle frequently operates in congested urban environments, the transmission fluid can be replaced earlier, around 40,000 kilometers. Conversely, if the car is often driven on highways, the replacement interval can be extended to about 80,000 kilometers. However, this also depends on the vehicle model, as different models have varying requirements. There are two common methods for changing transmission fluid in the market: 1. Machine-assisted fluid exchange: This method is performed while the vehicle is running, without the need to lift the car. Special equipment is used to exchange the fluid. This approach keeps the fluid circulating within the transmission, helping to remove sludge and impurities settled at the bottom, resulting in a cleaner transmission. Typically, around 10 liters of fluid can be replaced using this method. 2. Gravity drain method: This method is performed with the engine off, requiring the vehicle to be lifted so that the transmission fluid can drain naturally by gravity. It is the most common way to change transmission fluid. However, the gravity drain method is less effective than machine-assisted exchange, as it cannot completely remove all sludge from the transmission and typically only replaces about 4-6 liters of fluid.
