The principle of an automotive transmission is to use gear combinations with different numbers of teeth to achieve changes in speed and torque. Below are the functions of the transmission and operational precautions: Functions of the Transmission: Change the transmission ratio to meet the traction needs under different driving conditions, allowing the engine to operate under favorable conditions; enable the vehicle to move in reverse; interrupt power transmission when the engine is idling, shifting gears, or parking, cutting off power to the drive wheels; achieve neutral gear, where the transmission stops outputting power when the clutch is engaged. Precautions for Transmission Operation: When operating a manual transmission, ensure the gear lever is moved into the neutral position without shaking it back and forth, and avoid looking down at it; never force the gear lever, as this may cause misalignment or damage to the transmission mechanism. When operating an automatic transmission, avoid coasting in neutral and do not shift into reverse before the vehicle has come to a complete stop.
