How often should the transmission fluid in a car be changed?

[Mateo]

Different vehicle models have different replacement cycles. Below are the replacement intervals for transmission fluid: Manual transmission: Manual transmission fluid is generally recommended to be changed every three years or approximately 100,000 kilometers. Automatic transmission: Automatic transmission fluid is generally recommended to be changed every two years or approximately 40,000 kilometers. Continuously variable transmission (CVT): CVT fluid is generally recommended to be changed every two years or approximately 60,000 kilometers. Signs that indicate the need for transmission fluid replacement include: vehicle vibration, gear shifting hesitation; transmission overheating warning on the dashboard; engine stalling; unusual noises. The methods for changing transmission fluid are as follows: Loosen the drain screw at the bottom of the transmission to drain the old fluid, then refill. Remove the transmission oil pan directly to drain and refill: 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.
