An automatic transmission (Automatic Transmission) is a type of transmission that automatically changes gears in a car.
Simply put, an automatic transmission allows the driver to simply press the gas and brake, and it itself regulates which gear the car is in at the moment.
Inside the automatic transmission there is a complex system of gears that operate on the principle of hydraulics or electronics. When the driver presses the gas pedal, the automatic transmission selects and changes gears depending on the vehicle speed and engine load.
The goal of an automatic transmission is to provide a smooth, efficient ride by reducing the need to manually change gears and allowing the driver to focus on the road.
