How often should the transmission fluid of a Corolla be changed?

[JudahMarie]

The transmission fluid of a Corolla is generally recommended to be changed every 3 years or approximately 40,000 kilometers. The replacement cycle varies for different vehicle models. Below are the recommended replacement cycles for transmission fluid: Manual Transmission: Manual transmission fluid is generally recommended to be changed every 3 years or approximately 100,000 kilometers. Automatic Transmission: Automatic transmission fluid is generally recommended to be changed every 2 years or approximately 40,000 kilometers. Continuously Variable Transmission (CVT): CVT fluid is generally recommended to be changed every 2 years or approximately 60,000 kilometers. The methods for changing transmission fluid are as follows: Unscrew the drain plug at the bottom of the transmission to drain the old fluid and then refill with new fluid. Remove the transmission oil pan directly to drain the old fluid and refill with new fluid: This method is more thorough than the previous one, as it removes impurities from the bottom of the oil pan. Use a circulation machine to change automatic transmission fluid: Dynamic fluid exchange using an intelligent circulation machine can filter and clean sludge and impurities inside the automatic transmission.
