The automatic transmission's primary job is to allow the engine to operate in its narrow range of speeds while providing a wide range of output speeds.
Without a transmission, cars would be limited to one gear ratio, and that ratio would have to be selected to allow the vehicle to travel at the desired top speed. The automatic transmission uses sensors to determine when it should shift gears and changes them using internal oil pressure. Later model cars are a combination of sophisticated hydraulics and computer-controlled components.
If you notice problems with your Automatic transmission, don't automatically assume that the problem is the transmission. Computers receive information from numerous sensors, process the information, and then signal/operate the transmission. Often, the problem is in one of the sensors, an electrical connection, or system ground.
One of the best ways to prolong the life of your transmission is through regular maintenance. Many factors affect the life expectancy of a vehicle transmission:
