Just like you should visit our Irving, TX Mazda dealership when you’re shopping for a new Mazda car, you can also rely on us to answer all your automotive questions. One question we receive often at our Mazda dealership near Dallas is how often drivers need to change their transmission fluid.

While most motorists know it’s important to have their oil changed every three months, or every 3,000 to 5,000 miles, few seem sure about when transmission fluid should be changed. How often you’ll need to change your transmission fluid depends on several things, including the type of driving you do and the kind of transmission your automobile is outfitted with. 

As a general rule, the fluid in manual transmissions needs to be changed more frequently than the fluid in automatic transmissions. If your vehicle has a manual transmission, you should plan on having its fluid changed every 30,000 to 60,000 miles. Drivers who use their automobile for heavy-duty purposes may need to have their transmission fluid changed more often, possibly every 15,000 miles. It’s necessary to change the fluid in manual transmissions because it will become contaminated over time. If the contaminants aren’t removed, they’ll shorten the lifespan of your transmission. 

Although it may seem counter-intuitive, the fluid in an automatic transmission may not ever have to be changed. While there are obviously exceptions, it’s typically advisable to change the fluid in an automatic transmission every 60,000 to 100,000 miles or so, just to be safe. Automatic transmissions generate more heat than manual transmissions do. For this reason, the fluid in automatic transmissions can degrade and break down the more you drive your automobile. 

If it’s time to change the fluid in your transmission, make an appointment to bring your car into our Mazda service center serving Arlington, TX and surrounding areas. We look forward to servicing your vehicle at Freeman Mazda soon!
