Why Should You Never Change the Automatic Transmission Fluid in a Langdong?

[VanLevi]

For automatic transmissions in vehicles, the transmission fluid generally needs to be replaced every two years or every 40,000-60,000 kilometers driven. The specific requirements vary depending on the vehicle model, so please refer to the maintenance manual for details. Hazards of not changing the transmission fluid: Prolonged failure to change the transmission fluid can lead to damage in the transmission's shift control mechanism; cause abnormal wear on the gears and clutch plates inside the transmission; affect the normal operation of the transmission, resulting in damage to the transmission valve body. Over 99% of automatic transmission failures are caused by overheating of the fluid and the accumulation of impurities due to prolonged non-replacement of the fluid. Therefore, regular replacement of ATF (Automatic Transmission Fluid) is crucial for automatic transmission maintenance. Methods for changing transmission fluid: Loosen the drain screw at the bottom of the transmission to drain the old fluid before refilling, or directly remove the transmission oil pan to drain and refill the fluid. This method is more thorough than the previous one, as it removes impurities accumulated at the bottom of the oil pan. Alternatively, a smart circulation machine can be used for dynamic fluid replacement, which filters and cleans out sludge and impurities inside the automatic transmission through a circulation process.
