How an Automatic Transmission Works

Here's how an automatic transmission works in your passenger automobile. The automatic transmission is responsible for providing a selection of gear ratios between the engine and drive wheels of a car. The transmission uses the principle of planetary gears, which are always meshed together to vary gear ratios. This results in speed reductions and torque multiplication. Most gasoline engines are tuned to generate more power as the RPM increases. Thus a low gear ratio, which multiplies torque, helps a
