How Often Should Transmission Fluid Be Changed in a New Car?

[DiBradley]

Automatic transmission fluid is generally changed every 40,000 kilometers. Below is an introduction to transmission fluid: 1. Transmission fluid requires regular replacement, especially for automatic transmissions. The specific replacement interval varies depending on the vehicle model, and design requirements differ as well. The most accurate approach is to refer to your car's maintenance manual, which provides detailed instructions. 2. Manual MT transmission fluid is the cheapest to replace and has a relatively long replacement interval, typically lasting around 80,000 kilometers. Most models require about 3 liters of fluid. 3. Automatic transmission fluid is usually changed every 40,000 kilometers. The total fluid capacity for most transmissions is 6-8 liters, but due to structural reasons, it is often impossible to completely replace all the fluid at once. 4. Typically, CVT fluid begins to degrade after reaching this mileage. The total fluid capacity inside the transmission is generally 6-8 liters, with some models requiring around 10 liters. Similar to AT transmissions, due to the presence of a torque converter, it is usually not possible to completely replace all the fluid at once.
