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.
