Does red transmission fluid need to be replaced?

[VanSimon]

Red transmission fluid does not need to be replaced. Under normal operating conditions, transmission fluid appears red or yellow, odorless, and semi-transparent. After some time of use, the color of the transmission fluid may turn brown, at which point it is recommended to replace it. When it turns black and emits a burnt smell, it must be replaced immediately. Transmission fluid replacement intervals: Manual transmission: Manual transmission fluid is generally recommended to be replaced every three years or approximately 100,000 kilometers; Automatic transmission: Automatic transmission fluid is generally recommended to be replaced every two years or approximately 40,000 kilometers; Continuously variable transmission (CVT): CVT fluid is generally recommended to be replaced every two years or approximately 60,000 kilometers. Transmission fluid replacement methods: Loosen the drain screw at the bottom of the transmission to drain the old fluid before refilling; Remove the transmission oil pan directly to drain and refill the fluid: This method is more thorough than the previous one, as it allows for the removal of debris at the bottom of the oil pan; Use a circulation machine to replace automatic transmission fluid: Dynamic fluid replacement with an intelligent circulation machine can filter and clean sludge and debris inside the automatic transmission.
