What Does My Transmission Do? Insight from a Mechanic

Each time you press down on your car’s gas pedal, various systems jump into action to move your vehicle forward. However, one often overlooked component is the transmission—that is, until you have a problem. So, if your transmission has been “out of sight, out of mind,” you might have some questions when your mechanic tells me you need transmission repair, service, or replacement. The local technicians at Chapel Hill Tire are here with insight.


What is a Car Transmission, and What Does the Transmission Do?


Your vehicle’s transmission sends power from your engine to your wheels. While that might sound simple, this vehicle component is powerful and complex. When your engine creates power, your transmission will harness, transport, and regulate it—ensuring your wheels can move at your desired speed.


Bridging these two essential car components makes your transmission vital to a vehicle’s functioning. There are several different transmissions, most notably the automatic and manual. Therefore, your transmission care and maintenance will depend heavily on which kind of transmission your car has.


How Long Do Transmissions Last?


With proper maintenance, transmissions often last for the lifespan of a vehicle—which is why many drivers consider transmission troubles synonymous with vehicle replacement. Like engine failure, there are plenty of reasons to replace a failed high-value car component or buy a new vehicle.


You can also find a mechanic (like Chapel Hill Tire) that will install both new and remanufactured transmission replacements. Remanufactured components have been salvaged or repaired—offering a more affordable alternative.


However, because transmissions are usually so reliable—they are often covered under your powertrain warranty. Auto manufacturers often include coverage for years—up to 10-year/100,000 miles in some cases. Of course, this warranty will depend on your car manufacturer. Additionally, some manufacturers will void your warranty if you do not keep up with routine maintenance. So, what kind of maintenance does the transmission need?


What Kind of Transmission Service Do I Need?


Your recommended transmission service will depend on a variety of factors, including your vehicle’s make, model, and transmission type. However, the most common cause of automatic transmission failure is worn-out transmission fluid. This fluid keeps your transmission cool and lubricates these components so they can work together seamlessly.


Most vehicles need a transmission fluid flush every 30,000 miles. However, you can check your owner’s manual or ask your local mechanic for recommendations specific to your vehicle.
