Gear Up: Transmission Service at Car Doc On The Island in Venice

The transmission system in your vehicle allows you to change gears. Lower gears are power gears. They get your vehicle moving and get it up hills. Higher gears get the vehicle up to speed and get it rolling faster. If you have a standard transmission, then you have to do the work of shifting gears yourself. But with an automatic transmission, the vehicle shifts gears on its own. It automatically starts out in low gear and automatically shifts to high gears as it gets rolling. Again, it will automatically shift to a lower gear to climb hills or when you need a burst of speed.

How does it know when to change gears? Today's automatic transmissions are computer-controlled. The computer gathers information about what the vehicle is doing and changes the gears as needed.

Automatic transmissions are becoming more sophisticated all the time. More gears, or “speeds,” are being added. Almost all vehicles have at least four speeds. Five or six is common. Some are even increasing to seven or eight – up to ten. Adding gears has a lot of advantages for Venice vehicle owners: it improves fuel economy and increases performance.

But there is a drawback for drivers in Venice: more gears equal more parts and a more complex transmission system. Plus, all those parts need to fit into the same space as older, less complex transmissions. This means that today's transmissions are engineered to much tighter tolerances. In other words, they demand meticulous care from Venice drivers. Transmissions are designed for durability. But that durability can be compromised if they aren't given proper care.

That's why changing transmission fluid is such an important part of preventive maintenance for vehicles in Venice. Transmission fluid lubricates the transmission and keeps it in good working order. But if the fluid runs low, transmission parts will wear out quickly or suffer damage due to increased friction. The transmission can even fail.

Dirty transmission fluid can clog the small passageways in the transmission, blocking lubricant from reaching all of its parts. Again, this can lead to increased wear, damage or failure.

New transmissions aren't cheap. Repairing them isn't cheap either. But changing transmission fluid is fairly inexpensive at Car Doc On The Island in Venice. That's why responsible car care includes maintenance on the transmission system at Car Doc On The Island. It doesn't take a genius to figure out that periodic fluid changes aren't just good auto advice, they actually pay for themselves by preventing transmission repairs.

Diagnosing Your Vehicle at Car Doc On The Island in Venice

When we Venice residents get a car repair bill, we really shouldn't be surprised to find “diagnostic fees” as one of the line items. When we get a computer fixed, there is usually a charge for the time it takes to diagnose the problem. When we go to a medical doctor, most of his fee is for his ability to diagnose what's wrong. It's no different with our vehicles.

Some diagnoses are fairly simple. Brake repairs at Car Doc On The Island usually require only a visual inspection, for instance. But other problems are much more difficult to diagnose. An intermittent engine problem, for example, takes time and expertise to pinpoint.

Modern vehicles have multiple computers that monitor a variety of sensors throughout the vehicle. When one of those sensors has a reading that is higher or lower than the standard parameters, the computer turns on the Check Engine light. Technicians at a service center such as Car Doc On The Island in Venice can scan the engine's computer for a trouble code. This code tells the technician which reading is too high or too low.

That's where some Venice residents get confused. They think that this reading concludes the diagnosis, and they don't understand why the diagnostic fee is as much as it is when all the technician did was to scan the computer. But the truth is the trouble code is only the beginning of the diagnostic procedure.

Remember, the trouble code only tells which reading is out of parameter. It doesn't say what is causing the reading to be too high or too low. Your Car Doc On The Island service technician still has to find the underlying problem. It's a lot like going to the doctor. He can take your temperature and discover that you have a fever, but that doesn't tell him what is causing your fever.

Automotive diagnostic technology can cut down the time it takes to figure out what's wrong with a vehicle that isn't running right. But it doesn't do away with the need for your friendly and knowledgeable Car Doc On The Island service technician to make a proper diagnosis. Car care, like medical care, still requires the human touch.

FL: What Is the Risk of High Oil Change Intervals?

FL residents may have heard that vehicles don't need their oil changed as often as they used to. That's true. But it's not the whole story.

Owing to improved engine technology and higher oil quality, most newer vehicles can go longer between oil changes than their older counterparts.

So what is a good time interval for oil changes? How do FL residents know when to change it? And why do we change it in the first place?

Oil lubricates a vehicle's engine, which protects it from friction damage. Over time the oil can collect dirt and contaminants that inhibit its performance. But dirty oil isn't the only problem for FL residents. What you really want to avoid is called oil sludge.

Oil sludge is caused by moisture in the oil and by hot spots in your engine that burn off oil. This sludge is a gooey gel that can clog engine passageways, which can block lubricants from reaching vital engine parts. The result can be engine wear or even engine failure.

Sludge forms rapidly in an engine that is driven under what are termed “severe conditions.” A vehicle's owner's manual includes recommendations for oil change intervals under both normal and severe conditions. Severe conditions include towing a trailer, driving in polluted or dusty conditions, hauling heavy loads or using a car top carrier. Also, extremes in climate such as very hot or very cold temperatures constitute severe conditions for vehicles.

Some people may be tempted to overlook the severe conditions preventive maintenance schedule in their 's owner's manual because of the word “severe.” But consider this: the most common form of severe conditions is stop-and-go driving, rush hour commuting or only driving your vehicle on short trips around the area.

When a vehicle only makes trips under four miles/six kilometers, or under 10 miles/16 kilometers in freezing conditions, the engine doesn't get warm enough for condensation in the oil to evaporate. The result? You get oil sludge build-up. If your driving patterns are the same as any of the conditions that count as severe, you should be changing your oil more frequently under the severe conditions schedule. 

The team at Car Doc On The Island in Venice can help you understand what type of oil to use in your vehicle and how it can affect your oil change schedule. Some vehicles are filled with synthetic or synthetic-blend oil at the factory. The owner's manual will recommend that this oil continue to be used in the vehicle, and oil change intervals will be based on this type of oil.

Also, if your vehicle uses conventional oil, but you have some of those severe driving habits we talked about, you can switch to a premium-grade oil to give your vehicle extra protection. The answer to why we change our oil is fairly simple: to protect our engines and make our vehicles last longer and run better. But the answer to how often to change our oil is more complex: it depends on our vehicle, our driving habits, where we live and what kind of oil we use.

When it comes to oil changes, a little information can go a long way to helping people save money and extend the life of their vehicles. Stay safe, and stay on the road.

Differential Service

When you're driving and turn a corner, you probably aren't aware of all that's going on with your wheels.  The outside wheels have a longer distance to travel than the inside wheels, so there are gears that allow the wheels to go at different speeds when you turn. 

That set of gears is called a differential.  In front-wheel drive vehicles, it's by the transmission and called a transaxle.  Rear-wheel drive vehicles have the differential, naturally, on the rear axle. Many all-wheel and four-wheel drives add a center differential since power has to go to the front and rear wheels. (Some newer vehicles power wheels with electric motors, but that's a whole different story.)

Time and distance traveled eventually can take their toll on the differential, and you may notice some noises you hadn't heard when your vehicle was newer.  Sometimes you'll hear a whir that might change in pitch when you turn.  You may hear clicking sounds when you're moving.  Others describe rumbling sounds coming from underneath during a turn. Another symptom of possible differential problems may be vibrations or shakes the faster you go. 

All of these could be signs that you have problems with a differential. One common cause of differential problems is the gears aren't getting enough lubrication.

These can all have serious effects on your driving.  You may find it hard to turn, or your wheels may lock up. That could put you or drivers around you in a dangerous position. 

It's better to take care of differential problems before they get too serious.  Bring in your vehicle so we can have a technician check yours out.  They can see if there are any differential fluid leaks or failing gaskets.  In some cases, we may recommend your differential fluid be replaced.  And if there are any mechanical issues, some components may need to be replaced as well. 

When your differential is maintained, you'll be doing your vehicle a good turn.

A Door No One Can Step Through (Fuel Door Repair and Maintenance)

Your vehicle has lots of doors including that one usually near the back on the vehicle's side.  That's the fuel door, something you use every time you gas up.  These endure hundreds of open-and-close cycles, usually without any problems.  But when they act up, it can be a major inconvenience for you.

When they stick in the "open" position, it can present real dilemma.  You can still pump your gas, but do you just drive around with that flap sticking out the side? What happens if someone steals the gas cap or it gets damaged? What happens if it rains? Yep, it's decision time.

A fuel door that sticks open can be due to a number of factors.  The hinge on the door may have broken, possibly from corrosion or it may have been hit sometime.  Some vehicles have a cable that operates the door and it could be loose.  The latch that holds the door shut could have broken or it, too, could be bent from something hitting it. 

You probably want to take care of this sometime soon since your gas cap is wide open and unprotected when the door doesn't shut.  Plus, it's possible that the door could be torn off completely.  Often a stuck open fuel door can be fixed fairly inexpensively and quickly depending on the type of mechanism your vehicle has. Looks like it's an open and shut case.
