Let?s Shift Gears (Transmission Fluid Replacement)

Posted August 17, 2025 4:53 AM

If you have a vehicle with an automatic transmission, you probably never think about gear shifting.  When motor vehicles were invented, all of them had to be shifted manually.  But that wonderful self-shifting transmission, referred to these days as simply an “automatic,” changed everything.

Automatic transmissions have a lot of moving parts, and they are bathed in a fluid that keeps them lubricated and cool. That fluid also is vital to the whole gear shifting process. 

As you might imagine, the longer that fluid does its job, the more chance it has to pick up some contaminants.  Sometimes a leak will spring up in an automatic transmission.  Dirty transmission fluid or not enough of it will both create problems. It may cause your Check Engine light to come on, or your transmission may run rough and make strange noises.

The best strategy is not to let it get to this point.  That means you should have your transmission fluid replaced at regular intervals. Your vehicle’s manufacturer recommends how often you should have your transmission fluid changed. You should also have the fluid checked at regular intervals to detect if any problems crop up before that recommended interval. They’ll check not only the level but also inspect its condition.

Keep in mind that most automatic transmission problems are caused by overheating. You can reduce your chances of transmission failure by making sure your transmission—and its fluid—is regularly inspected and the fluid is replaced when it needs to be.

After many sour experiences—and even betrayal—from other auto shops, I feel compelled to share my heartwarming experience with the amazing, kind, and truly caring team at Ken’s Auto. From the moment I met Todd and Cindi, who run the shop with such grace and warmth, I felt something I had never felt in an auto shop before: ease. Every time I walk through their door, I feel relaxed, knowing I am in good and loving hands. They consistently go above and beyond to make sure I feel seen, valued, and treated with genuine care—a rare gift in this industry. And then there is Mike—the mechanic with a golden heart and golden hands. I have never felt so safe and confident on the road until he began servicing my car. His skill, attention to detail, and integrity have transformed the way I drive. For the first time in years, I feel protected behind the wheel. Everyone at Ken’s Auto operates with warmth, honesty, and integrity—the qualities every human needs and deserves but so rarely receives. After years of running into shops that took advantage of my vulnerability, I can finally say I have found a place of milk and honey—a shop led not just by people with heart, but people who lead with their heart. Every time I step into Ken’s Auto, I know their priority is simple and sincere: to make sure my car is in the best condition so that I am safe on the road. And thanks to them, I drive with trust, comfort, and peace. I urge anyone seeking true care, respect, and honesty for their vehicle to give this incredible team a chance. With full confidence, I guarantee—you will not be disappointed. Lastly, I want to say that their prices are better than any other shop I’ve been to, which only adds to the peace of mind they give me.
