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

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.
The transmission warning light may be caused by excessive transmission fluid temperature or abnormal fluid level. My old car once encountered this situation. After a long-distance drive, a warning suddenly popped up on the dashboard, which scared me into pulling over to check immediately. It turned out there was a leak in the oil pan. This issue can range from minor to serious—aside from fluid problems, it could also be a sensor error, especially in older models with aging wiring, or a stuck solenoid valve causing abnormal gear shifts. Sometimes, the jerking sensation during sudden acceleration is a precursor. It's recommended not to push through but to use a low gear and drive slowly to the repair shop, avoiding sudden braking on the way. Additionally, I've noticed that the probability of false alarms from the warning light is higher in humid weather, and restarting the vehicle might make it disappear in such cases.
