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 i ... read more

When you turn on the air conditioning in your vehicle, you expect cool air to come out of the vents.  You depend on it, especially in hot weather, but it can also be important in humid weather when you need it to help defrost your windows and windshield. The air conditioning system has a lot of parts to it.  It has fans and blowers to move the air through the vents into the cabin.  It has parts that take hot air and cool it off. An electrical problem can be as simple as a broken switch or a broken blower motor. The air may not be getting cool because a hose in the system is broken or the refrigerant has leaked out.  Two major components are the compressor and the condenser.  The compressor pressurizes the refrigerant, one step in the air conditioning process.  The condenser takes that hot refrigerant and cools it down. It also reduces the pressure. Because the climate control system in your vehicle is so complex, it’s best to leave the diagnosis to a ... read more

If you’ve noticed your vehicle’s ride has lately been bumpy or you’re hearing strange noises when you drive over bumps, you may need new struts.   The strut assembly is part of your vehicle’s suspension system that’s used to absorb the irregularities on the surfaces you drive on. You have probably heard of shocks or shock absorbers.  A shock is a piston with gas or liquid inside.  When you hit a bump, that shock absorbs the blow. Struts are similar to shocks but they also have a coil spring for extra strength.  They’re often used in the front of the vehicle because of the engine’s extra weight.  As you might imagine, your struts take a beating every day.  Eventually, they will wear out, and your wheels and tires won’t stay connected to the road as well as they used to. In addition to a bumpier ride, you may notice your tires starting to wear with failing struts because those tires aren’t in contact ... read more

Many of us have become aware of how important it is to keep our planet’s air clean, and your vehicle has a key component that helps do just that: the catalytic converter.  It’s in the exhaust system, and its job is to superheat unburned, harmful byproducts in the exhaust, so they don’t get spewed out into the atmosphere. There’s another important purpose the catalytic converter has: it improves your vehicle’s efficiency.  Most of us don’t give the catalytic converter much thought until it breaks or someone steals yours, something that’s been happening much more frequently in recent years.  The reason people steal them is that catalytic converters use precious metals such as platinum, palladium, and rhodium to do their job. So, they contain valuable materials thieves can sell. The most likely reason you will have to replace your catalytic converter is age.  The more distance your vehicle travels and the more hours your engine ... read more

When one of your vehicle’s warning lights comes on, the first thing that comes to mind is, “Oh, no, what’s wrong now?” When it’s the battery light, it means there’s something wrong with your vehicle’s battery or charging system.  And because both are important for your vehicle to work properly, it’s a good idea to get it checked out.  Here are some things that may cause a battery light to illuminate. It could be that your battery has failed.  It could be on its last legs or completely dead.  When it isn’t showing it has the voltage it should, your vehicle lets you know. If it’s not the battery itself, it could be the system that charges it.  The alternator is part of that system and could have a problem.  It could be putting out no power, too little power, or too much.  The alternator may not be working because the belt that drives it (using the engine’s mechanical power) could be broke ... read more
