Important Components of an Automatic Transmission

Your vehicle's transmission is a highly-complex mechanism composed of numerous interworking parts that must work flawlessly together to ensure the proper transfer of power. At the first sign of a transmission problem, you'll want to be proactive about addressing it. Otherwise, the problem could quickly worsen to the point that you need major repairs---or perhaps a new transmission altogether. Here's a look at the different parts of an automatic transmission.

Pump

The pump pressurizes transmission fluid for the torque converter and transmission. In automatic transmissions, the pump plays a crucial role in creating the necessary fluid pressure.

Transmission Fluid

It's of great importance that you always drive with the proper amount of automatic transmission fluid. Because transmission fluid can become polluted, it should typically be changed every 30,000 to 60,000 miles.

Clutches & Bands

These components help to ensure that gears are able to properly rotate, engage, and disengage.

Planetary Gear Set

All aspects of your transmission are dependent on the planetary gear set, which consists of planet gears, a sun gear, and a ring gear. Your gear ratios are determined by the planetary gear set.

Torque Converter

Torque converters are hydraulic fluid couplings. Through this coupling, the engine and transmission are connected. As you might expect, these converters are integral to generating torque that allows your car to accelerate, as well as to remain in gear while you're stopped.

Valve Body

The valve body plays an important role in monitoring incoming transmission fluid and dictating where it needs to go.

Sensors

Sensors take into account your operating speed and determine which gear you should be in.
