Auto ( Automatic Transmission ) – Transmission in which shifting while driving happens automatically ( without the driver ), depending on the vehicle speed.
All automatic transmissions have a minimum of 4 modes : P – Parking ( wheels locked ), N – neytralke (idle ), R – reverse , D – movement . Changing modes is possible only when the brake pedal depressed . In addition to the “classical hydraulics ” , there are several types of automatic transmission : tiptronic ( automatic transmission with manual shift ) , CVT (continuously variable automatic transmission ) , robotic mechanics robotic mechanics with two clutches.
Of the benefits of such arrangements include the following items : an increase in driving comfort due to the lack of a clutch pedal , smooth shifting device itself , the protection of the engine and chassis of the car Overload .
Disadvantages of automatic transmission – large transmission loss of torque, which increases fuel consumption .
