How Many Kilometers Should the Transmission Fluid Be Changed for a New Car?

[VonDerek]

In general, the automatic transmission fluid (ATF) in a car should be changed every two years or every 40,000 kilometers. Here is a detailed introduction to car transmissions: 1. Introduction: A device that changes the speed ratio and direction of motion. It is used in cars, tractors, ships, machine tools, and various machines to alter the torque, speed, and direction of motion transmitted from the driving shaft to the driven shaft under different working conditions. A gear-driven transmission generally consists of a housing and several gear pairs. 2. Function: While driving, to adapt to different working conditions, the car's driving force and speed need to vary within a certain range. However, the existing engine's torque and speed variation range cannot meet this requirement, hence the need for a transmission.
