Often known by many names and abbreviations, such as AT, auto transmission, self-shifting transmission, or n-shift transmission (' n ' is the number of forward gear ratios). The automatic transmission, as these names indicate, helps the vehicle to automatically change gears on acceleration and deceleration without the hassle of manual shift. This handles the internal combustion mechanism of the engine efficiently and controls speed, torque and strength to produce varied outputs, without pause or jerks. The automatic hydraulic transmission is the most common transmission used in today's cars. Larger, equally working parts are used in gigger vehicles. In place of friction clutch, a fluid coupling is used which changes gears by hydraulically locking and unlocking the planetary gears. The automatic transmission has set gears with parking gear that locks the output shaft to keep vehicles from rolling back or forward. For vehicles where speed such as a forklift or lawn mower is limited, a simple torque converter is used to shift energy from the engine to the wheels.

There are other types of systems other than the hydraulic automatic transmission system that are also used in the automotive industry. These are Continuous Voltage Variable (CVT) and Semi-Automatic Transmission. Such systems use the transmission control unit to anticipate gear changes, instead of allowing the driver to manually shift gear. During internal operation, standard automatic transmissions differ widely from a CVT and Semi-Automatic transmission system. The CVT makes use of a belt or torque transmission to allow the transmission to have an infinite number of automatic transmission gears instead of finite gear ratios. In semi-automatic transmission, the clutch is operated by electrohydraulic processes, in the present as in the manual transmission. In some models, one may also consider the manual shifting facility such as paddle shifting, whether automatic, semi-automatic or CVT. The best advantage of an automatic transmission system is that there is no need to coordinate between the automatic transmission clutch and the gear. This decreases exhaustion and makes a more relaxed and relaxing ride for the rider. This service is more useful when the driver has long distances to travel. Automatic transmission system has also enabled many people with disabilities to be self-sufficient in driving. It also makes for a more concentrated drive on the lane, thus reducing accident chances. The automatic transmission also improves vehicle control at low and idle speeds. Nonetheless, the common hydraulic system reduces the power transferred to the engine and the drivetrain due to the fluid coupling that is attached to the gearbox. This may result in lower torque ratings compared with the same engine specs of manual transmissions. It can also lead to reduced fuel economy in urban traffic.

An automatic transmission system operates using a number of moving parts. It occurs with the use of different mechanical elements, fluids and electrical parts working together in full synchronisation, allowing for smooth ride and preventing jerks when moving. The power is passed by the engine to the torque converter pump. Power from the pump goes via the transmission fluid to the converter turbine. The fluid is sent back via the stator by the turbine. Transmission fluid power is compounded by a stator, allowing the pump to transfer more power to the turbine. This results in the converter being rotated to a vortex control. Central shaft-connected turbine links it to the transmission. The shaft spins like turbine spins, which transmits power to the transmission gear unit. The transmission determines whether to shift the gears or to remain stationary, depending on the engagement of the clutch disc and brake unit. The gear system decides the gear ratios based on the moving parts and calculates how much power the drivetrain requires from the transmission. That is basically how an automatic transmission system works. There are different sensors and control modules that support all of the system's physical functions.
