The saying that "trucks have automatic transmissions" has become history. Automatic trucks were not only available abroad a few years ago, but also domestic trucks ended the history of no automatic trucks.

After several years of popularity, the truck with automatic transmission is no longer so mysterious. Because the freight car needs strong power and large torque in operation, in order to save energy, the power transmission efficiency of the gearbox is high, which puts forward more stringent requirements for the gearbox. For example, the average passenger car has five or six gears, while the trucks generally have more than eight gears. Due to the development of new technology and the renewal of parts and materials, the transmission torque and efficiency of automatic gearbox have been greatly improved. In order to make it easier for truck drivers to drive, it is logical to install automatic gears on trucks.
