Your car’s transmission is a complex mechanism that contains myriad parts which work together to transfer power from the engine to the wheels. When an issue with any component of the transmission arises, it’s important to address it ASAP. If you delay, you could end up needing transmission repairs that are far more expensive than should’ve been necessary. At Rowlett Transmission, our mechanics specialize in identifying and fixing all types of transmission trouble. Don’t hesitate to give our local transmission shop a call when you first notice a sign of a transmission problem. Here’s a look at the important parts in an automatic transmission.


Torque Converter

Torque converters are hydraulic fluid couplings that connect the transmission and engine. Torque converters play a crucial role in the acceleration process, as well as keeping your vehicle in gear while stopped. 


Transmission Fluid

It’s very important that you’re always driving with the right level of clean transmission fluid. This is because transmission fluid plays a number of important roles, including lubrication, enabling correct fluid pressure, rust prevention, and cooling. Transmission fluid should be exchanged in accordance with your owner’s manual’s mileage specifications.


Pump

The transmission pump needs to be working strongly so that fluid pressure is able to reach its proper level.


Planetary Gear Set

Your planetary gear set consists of planet gears, a sun gear, and a ring gear. This gear set plays a crucial role in determining gear ratios. 


Valve Body

The valve body is the automatic transmission’s control center. Through its channels, it directs transmission fluid to valves as needed. 


Sensors

Sensors keep tabs on how fast the car is moving and determine which gear the vehicle should be in as you accelerate and decelerate. 


Clutches & Bands

Clutches and bands play a central role in gears’ ability to rotate, engage, and disengage.
