The Sign of the Shield (Heat Shield Repair and Replacement)

Even in the months where temperatures are cooler, heat is still an enemy of your vehicle.  When your engine runs, it creates heat, so there are numerous heat shields that protect other parts from those higher temperatures. Heat shields are installed around several areas of the exhaust system.  Others prevent heat from reaching parts of the vehicle.  Still others prevent heat from reaching the ground (or maybe grass underneath) and starting a fire. 

If you remember your space travel history, you'll know how important a heat shield can be. John Glenn was the first American to orbit the earth, but during that maiden orbital flight, a sensor on board was indicating the heat shield on his capsule, Friendship 7, was loose.  If it had come off, his spacecraft could have burned up upon re-entry.  Fortunately, the heat shield stayed on, and Glenn made history.

Unfortunately, the heat shields on your vehicle don't have warning systems like the space vehicles did.  So you have to maintain them.  Heat shields are constantly exposed to elements like water, salt, sand and dirt.  That makes them prone to rusting and corroding.  Here's one unfortunate fact: Materials that make them good at preventing heat transmission also are soft and vulnerable, often aluminum or special fabric. 

One sign a heat shield will give you that it's loose is noise; you'll sometimes hear it rattling underneath your vehicle when it's running. One way to locate it? Put your vehicle in park, leave the engine running and take a listen outside.  It's usually pretty easy to pinpoint the location.

Make a note of the noise when you are talking with your service advisor. It's important to have those heat shields working correctly so the heat is kept away from your other vehicle systems and combustibles on the ground. The good news is that heat shields can frequently be inexpensively repaired or re-attached.  In other cases, they should be replaced. 

Missing or loose heat shields? Let's just say they're not cool.

Fears and Gears (Signs of Automatic Transmission Problems)

Automatic transmissions rule. The old days of shifting your own gears are a thing of the past for most drivers.  But automatic transmission trouble can be a big inconvenience for any driver if it comes at the wrong time in the wrong place.  Here are some signs to look out for that may mean you are having transmission issues.

When you are driving, your vehicle seems to slip in an out of gear without you touching anything.  That's what some call, not surprisingly, a "slipping transmission." 

When your vehicle shifts from one gear to the next, you hear a loud "clunk." Transmissions are supposed to be nearly silent when they shift, so that noise is telling you something is wrong. 

If you notice there's a puddle of some fluid under your vehicle, your transmission could be leaking fluid.  Try to figure out what color it is (try putting a piece of cardboard underneath to capture some of the fluid).  If it is red or brown, that's a sign it could be transmission fluid. Sometimes you may smell the transmission fluid, too; it has what some consider a "sweet" odor.

You may have a warning light that goes on when your transmission fluid is low (it could be a special transmission symbol or simply the Check Engine light).  That light could also mean the fluid is too hot or has low pressure.

If you shift your vehicle into D (for Drive) and it doesn't move or slowly engages after some delay, you may be seeing the start of a serious problem.

Of course, you don't want a malfunctioning transmission to strand you at some inopportune time. So if your vehicle is showing any of these signs, arrange a time for a technician to check it out.  Not only are broken transmissions an inconvenience, they can be a safety hazard, too.
