Do you drive an automatic transmission? Here’s a short overview of its important parts

Keizer Transmission • 20 June 2023

Automotive transmissions are highly complex, with many parts that work in concert to transfer power from the engine to the drive wheels. If a problem with any part of the transmission develops, it should be brought to the mechanic’s attention as soon as possible. By being proactive, you’ll have the best chance of addressing the issue before it escalates and costs a lot more money to repair. At Keizer Transmission, we provide expert transmission service in the greater Salem, OR area. Here’s a quick look at the important components of an automatic transmission.


Valve Body

Your valve body serves as your automatic transmission’s control center. By way of its channels, transmission fluid is sent to valves as necessary.


Torque Converter

Torque converters, which are hydraulic fluid couplings connecting your engine and transmission, are integral to keeping your car in gear while stopped. Healthy torque converters also help to ensure proper acceleration.


Pump

For fluid pressure to reach its correct level, it’s important that the transmission pump is functioning like it should.


Planetary Gear Set

In your car’s planetary gear set, you have planet gears, a sun gear, and a ring gear. A healthy planetary gear set is essential to properly determining gear ratios.


Sensors

Sensors monitor the vehicle’s speed and calculate which gear you should be in as you accelerate and slow down.


Clutches & Bands

Clutches and bands are integral for gears to successfully rotate, engage, and disengage. 


Transmission Fluid

Transmission fluid serves a number of critical roles. It provides fluid pressure, lubrication, cooling, and rust prevention. It’s very important that you’re driving with the proper level of unpolluted transmission fluid. In your owner’s manual, you’ll see your vehicle’s exact requirements for how often your transmission fluid should be exchanged.
