What is an Automatic Transmission, and How Does it Work?
Because we use them every day, the operation of a car seems simple, but a car is a very complex machine. One of the most complex systems in the typical vehicle is the automatic transmission. This ingenious system performs a function—changing gears—that the driver would otherwise have to do. An automatic transmission executes gear changes automatically, so many drivers don't have a good sense of what this component is and what it does. But understanding how an automatic transmission works can make you a better driver and give you a better appreciation of what your car can do.
