It is possible that the automatic transmission's electronic components (sensors, solenoid valves, or the control module) have experienced intermittent or persistent faults. The transmission warning light may illuminate due to excessively high transmission fluid temperature, caused by factors such as overfilling the transmission fluid, or internal/external blockage of the transmission cooler (these situations mostly occur during high-temperature seasons). Additional information: 1. Function of the transmission: The transmission is a mechanism used to alter the speed and torque from the engine. It can fix or change the gear ratio between the output shaft and input shaft, also known as the gearbox. The transmission consists of a gear transmission mechanism and a control mechanism, with some vehicles also including a power take-off mechanism. 2. Transmission mechanism: Most transmission mechanisms use ordinary gear transmission, while some use planetary gear transmission. Ordinary gear transmission mechanisms typically employ sliding gears and synchronizers. When the relationship between the number of teeth on the driven gear and the driving gear changes, the transmission ratio (i) alters, which affects the output shaft speed under constant engine speed, thereby changing the wheel speed.
