The gearbox is divided into manual gear and automatic gear.When operating the manual transmission, pay attention to the shift lever moving to the neutral position, do not shake back and forth, and do not look down.Avoid pushing and pulling the shift lever hard to avoid deviating from the direction and damaging the transmission mechanism of the shift lever; when operating the automatic transmission, be careful not to slide into neutral gear, and do not hang it into reverse gear before the car has stopped.

An automobile transmission is a set of transmission devices used to coordinate the engine speed and the actual driving speed of the wheels, which are used to give full play to the best performance of the engine.During the driving of a car, the transmission can produce different transmission ratios between the engine and the wheels.

By shifting gears, the engine can work at the best power performance.The development trend of transmission is becoming more and more complex and the degree of automation is getting higher and higher. Automatic transmission will be the mainstream in the future.

The transmission mainly has the following functions:

①The transmission ratio is changed to expand the torque and speed range of the driving wheels to adapt to frequently changing driving conditions, while making the engine work under favorable operating conditions (higher power and lower fuel consumption)；

②The car can travel backwards while the direction of rotation of the engine remains the same；

Neutral gear is used to interrupt power transmission, so that the engine can start and idle, and it is convenient for the transmission to shift gears or output power.
