In an attempt to boost performance, tire manufacturers analyze the capabilities of their tires under a variety of road conditions and speeds to ensure the safety and durability of their tires. These tests are conducted on all factory-made tires whether they are intended for rain, snow, off-road, performance or fuel conservation. Among the many tests done on new tires is stopping distance. Stopping distance is the span of road that it takes for a vehicle to come to a complete stop.
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.
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?
