On this page, we will operate our way by way of an automatic transmission. We will begin with The crucial element to The full method: planetary gearsets. Then we are going to see how the transmission is place together, learn how the controls get the job done and discuss a few of the intricacies involved with controlling a transmission.
Area of the automatic transmission. The same as that of a manual transmission, the automatic transmission's Key task is usually to enable the motor to function in its slim choice of speeds whilst delivering a variety of output speeds.

The reverse clutch is engaged as well as engine drives the sun gear. The 2nd planet provider is braked and also the Sunlight gear causes the planet gears to push the second ring equipment in the opposite route to provide reverse drive.
2nd, there is not any equipment change within an automatic transmission car, so as you set the transmission into drive, anything else is automatic.
