Transmission Repair & Replacement

Let’s talk transmissions. Transmissions are heavy duty pieces of equipment that are designed to last a long time. But like any other machine, they’ll eventually wear out and need repair. So let’s focus on what you can do to push that day off as far as possible.

The first thing you can do is to make sure your transmission always has enough fluid. Transmission fluid cools and lubricates the transmission. When there’s not enough fluid, the transmission will run hotter and wear out sooner. The transmission fluid also provides the pressure needed to transfer power from the engine to the transmission. Not enough fluid, and your transmission won’t shift properly.

Your service center will check your transmission fluid level with a full service oil change and top it off if needed. If you see any transmission fluid on the driveway – it’s a reddish color – have us inspect it for a leak. A gasket, hose or seal could be leaking and may need to be repaired.

The next thing you can do to prolong the life of your transmission is to replace your transmission fluid on schedule. As you can imagine, all those gears grinding on each other result in lots of little bits of metal in the fluid. The more there is, the faster the transmission parts will wear out. Transmission fluid also contains detergents and other additives to protect your transmission. These additives are depleted over time, so old fluid doesn’t protect as well as new fluid. Your owner’s manual or service advisor will have a recommendation for when you should have a transmission service.

If your transmission isn’t shifting as smoothly as it should, or if you suspect a transmission leak, let us take a look at it. And ask if it’s time for a transmission service. Regular maintenance and taking care of small leaks right away will help your transmission last as long as possible.

How Often Should You Change Your Transmission Fluid

How often you should change your transmission fluid depends on your vehicle and your driving habits. The typical range of when to change your transmission fluid is every 30,000 to 60,000 miles, which we understand is quite large. When in doubt, check your owner's manual to see how often you should change your vehicle's transmission fluid.
