This simple barrier of accordion-folded paper may look insignificant but it's responsible for providing clean air to your vehicle's cylinders. This is important because air is just as crucial as fuel in the combustion process that powers the engine. Air is drawn through the engine air filter, then the air intake manifold and into the cylinders. There, it mixes with fuel to create the small explosions that power your vehicle.
A dirty engine air filter can prevent the cylinders from drawing in enough air, which throws off the fuel/air mix. This can result in poor fuel economy.
Once upon a time cars were simple: If the transmission didn’t shift right, you probably had a transmission problem. You took your car to the transmission shop and they fixed it. Simple, right? As with most stories that begin this way, times have changed. Today, when your car’s transmission isn’t shifting right, well, it could be the transmission, but there’s just as good a chance that it’s something else… something seemingly unrelated to the transmission.
Every so often you notice it: The transmission shifts a little late, or maybe it seems to miss a gear entirely. Then it’s okay again… for a little while. Worst of all, there’s no rhyme or reason behind the condition. One minute it’s fine, the next it’s not. So you pop the hood to check the transmission fluid level. Then you notice it: A big mountain of corrosion on the battery terminals. You’ll have to take care of that, but it can’t have anything to do with the transmission, right?
Prevention is better than cure. You've probably heard that said plenty of times. The phrase is most often used to talk about health and medicine, but it is just as valid to apply it to vehicles. It's great if your problem can be sorted without much trouble, but even better not to have a problem in the first place. This is especially true when it comes to your vehicle's transmission, as this can be one of the more specialized parts to repair. Not all transmission problems require an extensive overhaul, but they will all cause at least some trouble and inconvenience. Avoiding transmission problems is clearly preferable to even the problems that are quickest and cheapest repair. This is why it is important to ensure you take good care of your transmission. This will help prevent problems and keep it working smoothly. Ideally, it will mean that it doesn't develop any faults at all. Even if it does eventually go wrong, however, it is entirely possible that good care will mean the fault is less serious and easier to repair than it would have been otherwise.
Your transmission suddenly isn’t shifting right. So what’s wrong with it? Do you need your transmission rebuilt? Good question. Unfortunately, the answer is: No one knows. At least, not yet. To find out what’s causing your transmission problem, a technician is going to have to perform a series of tests. Basically, these tests are designed to answer the simple question: “Is it inside or outside?” That is, is the problem inside the transmission, or in one of the many control systems that operates the transmission?
They do great work, they only fix what needs to be done and they always use quality parts. - Roy
