Automatic Transmission and How it Works

Hyundai Automatic transmission

A transmission is a device designed for cars that connects the engine to the wheels. A car is a very complex machine and one of the most complicated and interrelated parts in the typical vehicle is the automatic transmission. This ingenious system implements gear changes automatically without the help of the driver.


Automatic Transmission

Car transmission comes in two main types, manual transmission, and automatic transmission. Manual transmission is one where the driver must manually shift and is still popular due to better fuel economy and being able to have control of the gears. However, many drivers prefer the convenience that automatic transmission has to offer. An automatic transmission is a multi-speed transmission that does not require any input from the driver to change gears. 


Basic Components of An Automatic Transmission

Planetary Gears: An automatic transmission consists of basic components. The Planetary gear set is at the heart of any automatic transmission. Multiple planetary gears are lined up to achieve different gear ratios. 


The Clutch: An automatic transmission does have a clutch system, but it is comprised of several discs inside a drum. Automatic transmission performs the same function as a manual transmission just differently. 


Torque Converter: The automatic transmission is equipped with a component called a torque converter which is a fluid coupling that drives the hydraulic pump and transmission input shaft. It performs the function that a mechanical clutch does in executing gear changes. 

Advantages of an Automatic Transmission


Many drivers prefer to drive an automatic because it’s easy to drive. Driving comfort is the best advantage of driving an automatic car. Automatic transmissions are engineered for great performance and versatility.  Automatic transmission has great acceleration speed with good fuel economy and is more powerful than a car with a manual transmission.
