What does it mean when a vehicle displays a transmission fault?

[VonEliana]

The reasons for a vehicle displaying a transmission fault may include a malfunction in the transmission computer or electronic components; transmission oil contaminated with impurities or severely insufficient; internal transmission parts damaged; or false or incorrect fault light reporting. Below is relevant information: Transmission: A device that changes the speed ratio and direction of motion. Used in automobiles, 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 pairs of gears. Function: During vehicle operation, to adapt to different working conditions, the driving force and speed of the vehicle need to vary within a certain range. Since the existing engine's torque and speed variation range cannot meet this requirement, a transmission is installed.
