How does an AT work
WHAT IS AN
AUTOMATIC TRANSMISSION (A/T)?
An automatic transmission (AT) is installed at a point between the engine's rotation and the point where it is transmitted to the wheels.
An AT automatically changes gear depending on the car's running condition, and transmits rotation from the engine to the wheels.
An AT provides functions that the engine alone cannot perform, such as adding power on slopes, adjusting rotation speed as required during running, decoupling power when stopped, and applying the required opposite rotation when in reverse.
A/T STRUCTURE AND OPERATION
Automatic Transmissions consist of three components: a torque converter that transmits engine rotation to a planetary gear, a planetary gear train that changes rotation speed and transmits it to the wheels, and a hydraulic device that outputs commands to the planetary gear to change speed according to the car's running condition. Generally speaking, those are the three components of an automatic transmission.
Let us now take a look at the actual workings of an AT
