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

[VonCaroline]

Transmission fluid should generally be changed every two years or after driving approximately 50,000 to 80,000 kilometers. Below is more information about transmission fluid: Methods for changing transmission fluid: Loosen the bottom nut of the transmission oil pan to allow the old transmission fluid to drain naturally by gravity; connect the transmission to a circulation machine via a pipeline interface, and the old transmission fluid will be pushed out under pressure; remove the oil pan to change the fluid. Methods to determine if the transmission fluid needs changing: Pull out the dipstick and smell it closely—if there is a strong acidic odor, it indicates the fluid has deteriorated and should be changed; repeatedly rub the old fluid between your thumb and forefinger—if you feel impurities, poor viscosity, or even a gritty sensation, it should be changed; hold the dipstick at a 45-degree angle under light and observe the fluid droplets—if no metal shavings are visible, the fluid is in good condition. If there are many metal shavings, the fluid should be changed.
