What does the transmission fault warning light come on mean?

The car's gearbox fault alarm light is on, indicating that the car's gearbox is faulty. It may be that there is a fault in the connection line of a certain sensor. It can be diagnosed by a diagnostic instrument, and the specific fault location can be detected according to the fault code.

The transmission is composed of a variable speed transmission mechanism and an operating mechanism. The continuous development of science and technology has changed the transmission from the manual transmission to the current stepless transmission, so that the fuel consumption of the engine is relatively low when the power is high. The gearbox can change the rotation ratio of the car, expanding the drive wheel speed and rotation speed. The car's gearbox is one of the most important systems, providing the basis for the shifting of car gears, ensuring that the driving of the car can achieve the highest efficiency and achieve the best driving state.
