1. Transmission type noun
is a transmission speed change operating device of an automobile, a number of different diameter gears. The main transmission for shifting and the rotational speed of the engine crankshaft torque, to fit in the car starting, accelerating, and overcome the need for traveling wheel drive traction vehicle and the different requirements of various road driving conditions, such as different obstacles.
2. Classification transmission

● ordinary automatic transmission
● CVT continuously variable transmission / CVT gearboxes with analog gear
● dual-clutch gearbox
● AMT transmission
For example seen in PCauto parameter setting page “7 block manual” parameter refers to: this model is ordinary automatic transmission, with manual control gear function, seven gears.

play multifaceted role in the transmission of the vehicle, for example, running:
● It can make the car stable with a very low speed, but such a low minimum steady speed only by the speed of the machine is then difficult to achieve.
● gearbox reverse gear so the car can travel in reverse.
● its neutral long time to the automobile engine and the transmission at the time of starting the engine separation, and stop sliding.
