Cayenne here and today most vehicles have automatic transmissions, yet a lot of drivers around the South Bay only have a fuzzy understanding about what a transmission does.  So I am here to guide through the transmission process so to speak, I mean bark.   First, though watch my tutorial below!

 Think back to the last time you rode a bike in Los Altos. You started out in a lower gear and shifted to higher gears as you went faster. Down shift for hills, stuff like that. Think of your legs as the engine – there's an ideal speed you can pedal and you change gears to leverage the work you're doing.

Lower gears for power on hills or for starting out. Higher gears for more speed. That's what the automatic transmission does – it automatically starts in lower gears and shifts up to higher gears to go faster on CA roads. And it automatically shifts back down to climb Los Altos hills, pass or start up again.

Vehicle automatic transmissions have certainly gotten more sophisticated in recent years. They have more speeds than before: the base is four speeds, five is very common.

At Allied Auto Works, we routinely service transmissions with six speeds and several have seven or even eight speeds. As you can imagine, this means more parts. Any they all have to fit into roughly the same space.

Transmissions are computer controlled these days, with some high end transmissions having two or three computers. Transmissions are engineered to last. But they are also engineered to tighter tolerances. If a portion of the transmission is starved for lubrication, it can lead to failure.

Not enough fluid can starve the transmission, or dirty transmission fluid can clog small passages in the transmission. Then the lubricant is blocked and can't get to all the parts to protect them, so they wear out prematurely. The technicians at Allied Auto Works see far too many transmissions that needlessly failed due to neglect.

And, as you can imagine, repairing one of these new transmissions at any Los Altos service center can be quite costly. That's why owner’s manuals have a schedule for how often you should change the fluid and what type of fluid to use.

It's really important for South Bay drivers to carefully follow the manufacturer's transmission service schedule.

At Allied Auto Works in Los Altos, we hope you never become shiftless in South Bay because you didn't take care of your transmission,

Duke here and today it's all about Differential Service so watch my video and then let's bark about it.

Here at AutoNetTV, we have national viewers, like your neighbors in Los Altos, who write to us with questions or feedback. One common question we're asked is: "What is a differential and what does it do?" You may have been told by your Allied Auto Works service advisors Matt and Travis that your differential needs serviced, or it's seen it as an option upon the service menu. Differential service at Allied Auto Works covers a lot of things, so let's first talk about what a differential does.

As you drive through a turn, your outside wheels and inside wheels turn at different speeds. Kind of like the cars going around a race track - the ones driving in the outside lanes have a greater distance to travel than the cars in the inside lanes. The differential is what allows the outside and inside drive wheels to rotate at slightly different speeds so that the tires don't hop or skip while taking corners, or lose traction in dirt or snow on Los Altos area roads. Differentials have gears in them that transfer the power from the drive train to your wheels - which is why they're often referred to as gearboxes. The gears need to be very strong to do this work, and they need to be properly protected so that they'll last.

All vehicles in Los Altos have some form of differential. If you have a front-wheel drive car, your differential is sometimes called a transaxle and is located in the front. If you have rear-wheel drive, the differential is in the back of the car. Los Altos auto owners with a four-wheel drive vehicle have a differential in the front and the back - and in the middle as well. The center differential adjusts for differences in speed between the front and rear wheels.

Differential fluid lubricates and cools the gears. Over time, the fluid can get dirty from bits of the gears grinding off. The additives that keep the fluid clean and protect the differential break down over time. So your vehicle manufacturer has scheduled intervals for you to have your differential fluid changed. Talk to your friendly and knowledgeable Allied Auto Works service advisors Matt and Travis if you are not sure about your recommended schedule.

Have a great and free-wheeling day,

Whoa, put the brakes on and take a break!  Cayenne here and today we will bark about brakes and brake rotor service.

Think of how much abuse your brakes take. Day in and day out, they stop your vehicle when it's going fast and when it's going slow. Maybe your vehicle has been vibrating when you brake, or maybe it seems like your stopping distance is a little bit longer than it used to be.

Then it's time to get your brakes checked out. After all, you have to be able to stop if you want to be safe. Nearly all newer vehicles have disc brakes on the front, and many have that type of brake on all four wheels. That makes it likely you'll be getting disc brakes fixed at some time in your vehicle's lifetime.

Knowing how disc brakes work is as easy as riding a bicycle. If your bike had hand brakes, you'll probably remember a mechanism that squeezed a couple of pads on each side of your bicycle wheel when you applied the brakes. Disc brakes are similar; but instead of the bike wheel, there's a metal disc instead. If that disc is warped or has irregularities in it, it's going to vibrate.

It used to be that rotors were thick, and when they warped, a technician could "turn" them to scrape off a layer of metal so their sides were straight again. The latest vehicles are using thinner, lighter rotors with a slightly different construction. Now, it's likely that rotors that are resurfaced this way will not have enough metal left to work safely. In fact, some manufacturers advise only replacing rotors that are worn out.

Newer designs have reduced rotor prices, and in many cases, the labor cost of turning the rotors is higher than buying new. There are times, though, where your rotors can be resurfaced and still meet manufacturer specifications.

If you have a rotor replaced on one side of your vehicle, it might be a good idea to replace rotors on the other side, too.

Maybe you're looking for the new rotors to last longer than the ones that were on there. New technologies can offer a longer lifespan in a premium rotor. Armed with knowing the type of driving you do, you and your Allied Auto Works service advisor can make the best decision on which direction you want to go with your new brakes.

We all need a little break,

Hi Duke here and today we will bark about what to do if you happen to get in an accident and what follows afterward

Motorists in North America drive about 3 trillion miles/4.8 trillion kilometers every year. There are over 250+ million licensed drivers, and approximately 6.2 million accidents happen every year. Unfortunately, if we're going to drive vehicles, there are going to be accidents. Knowing what to do in case of an accident can help reduce the stress and cost of the situation. It can also protect you from false claims, incorrect judgments and unjust liabilities.

Never leave the scene of an accident. This is a crime, even if the accident is not your fault. If you leave the scene, it is referred to as a “hit-and-run,” and the fines are steep in CA. You can even lose your driver's license or spend some time in jail. If someone has been injured in the accident, most laws require you to help them. You must call for help. If you can, you must also render first aid.

Call 9-1-1 or get someone else to call 9-1-1 as soon as possible. Tell the operator if there are injuries or any circumstances that require fire services, such as leaking gas, broken utility lines or, of course, flames. Put out flares, turn on your flashers or lift your hood to warn other Los Altos motorists that there's been an accident.

File a police report. This can seem like a hassle when there are no injuries and only minor damage to vehicles. But you'd be surprised at the lawsuits and false claims that can arise from fender benders. You want a police report to protect yourself.

Don't talk about the accident with anyone except the police. After an accident, adrenaline is pumping and emotions are running high, and our first reaction is often to relive and recount our experience. Don't. Again, people can and will use your words against you, and in a highly emotional state, you may not say exactly what you mean. Entire court cases have hinged on the meaning of one misplaced word. Talk to the police. Don't admit guilt or fault, not to the police or to anyone else. People often feel guilt after an accident, but later, when details are analyzed, it turns out not to be their fault. Don't say, “I'm sorry,” but rather, “Can I help? What can I do?” Sympathy has often been misconstrued as an admission of fault. On paper, your words will sound more sterile than at the accident, and they can be used against you.

Collect contact information from everyone involved in the accident. Get the officer's name and badge number. Get the other driver's name, address, phone number, date of birth, driver's license number and expiration and insurance information. Get a description of the other vehicle as well as its license plate number and vehicle identification number (VIN). Most insurance companies don't keep records of license plate numbers, so the VIN is the best identifier you have of another vehicle.

This is going to be too much to remember once you're in an accident. So write down or make a note on your phone with the information you need.

Ask witnesses to wait for the police to arrive. If they can't, then get their contact information. Ask them to jot down what they saw. If witnesses refuse to give you their names, write down their license plate numbers. That way the police can find them if necessary.

After the accident, call your insurance company. Also, if you have or think you might have an injury that did not require immediate care at the accident, contact your physician right away.

There's a lot Los Altos drivers can do to prevent accidents. Defensive driving. Good car care and preventive maintenance. But if an accident does happen in the Los Altos area, we should be prepared to handle it well. It will ease the stress of the situation and protect us from potential legal and financial harm. Be prepared. It's good auto advice in every situation.  Ask our pros at Allied Auto Works for more safe driving tips the next time you visit.

Remember keep it safe on the road,

Cayenne here and today we are going to talk dirty, Dirty Fuel Systems that is.  So let's get barkin' on this dirty subject!

Is your vehicle sometimes hard to start early in the morning? When you turn the key, does it hesitate or stutter? If so, the problem could be the result of a dirty fuel system. Your vehicle's fuel system starts with the air filter and ends in the top of your engine. Over time, different parts of the system get dirty, which robs you of performance and hurts your fuel economy.

Most Los Altos vehicles have fuel injectors, rather than a carburetor. Fuel injection systems have fewer problems and require less adjustment. But they still need to be properly maintained. This is why your owner's manual has a schedule for cleaning your fuel injectors and other parts of your fuel system.

Some Los Altos residents are interested in buying fuel system cleaners that they can pour into their gas tank. You can do that - and there are lots of great products available that can help maintain an already clean fuel system - but these products cannot do a major cleaning. For that, you need to see Allied Auto Works. Allied Auto Works has the professional tools and chemicals to really do a complete service.

Allied Auto Works uses a process that gives your vehicle a deep, professional fuel system cleaning. You need to remove particles, gum and varnish from your fuel system and get those injectors running cleanly and efficiently. After a professional fuel system cleaning, you'll notice more power, better fuel economy and reduced exhaust emissions.

The cleaners also help prevent rust and corrosion in your fuel system and lubricate engine parts.

Fuel system cleaning is just one of those recommended service items that help keep your vehicle running strong. As with all maintenance, it can help avoid repairs that often result from not taking the right preventive steps. Los Altos residents will notice the difference in how well their vehicle runs. Check with your friendly and knowledgeable pros at Allied Auto Works to see when your vehicle is scheduled for a fuel system cleaning.

An ounce of prevention really is worth a pound of cure for Los Altos vehicles.

Let's take a cruise with me, Duke and today bark about cruise control!

When automakers first came out with cruise control, it was a real luxury item.  The older cruise controls used a mechanical vacuum system but it worked.  Well, some of the time. 

Nowadays, cruise control is all electronic, thanks to computers.  It's reliable and a real convenience on long trips.  Cruise control is offered on most vehicles and standard on a lot of them.  Because it's electronic, when it breaks, it's usually some electronic component.  Your vehicle's cruise can be the victim of a blown fuse. Or your vehicle's speed sensor, which—not surprisingly—measures your vehicle's speed, can also stop working.  And that will cause your cruise to stop cruising. 

Vehicles with cruise control also have a built-in feature that, when the brakes are applied, turns off the cruise.  With electronic cruise control, that happens thanks to the brake pedal switch, and if a problem develops in that switch, the cruise might not work.

The newest cruise control is called "adaptive." What that means is that it will maintain your vehicle's speed as well as the distance between you and the vehicle ahead of you.  That means if a car ahead of you slows down, your vehicle will slow down to the same speed and even stop if the car ahead stops.  Pretty cool, right? As you can imagine, adaptive cruise control is more sophisticated and has many more components than standard cruise.  The systems vary from manufacturer to manufacturer, but they use on-board radar units and cameras to calculate what your vehicle should do to maintain a safe distance and speed. 

Finally, there are still some of the older style cruise controls out on the roads.  They'll stop working when the vacuum actuator develops a problem, a vacuum hose starts leaking or breaks or the cable between the actuator and the throttle kinks, breaks, seizes up or becomes detached. 

If your cruise control isn't working, your service repair facility will be able to determine what kind your vehicle has and what it will take to fix it.  Good news for the cruise blues.

Keep on cruisin!

Hi, it's Cayenne and somethings are met to last and your vehicle is no exception.  So today I will bark about making your vehicle last with some help from our friends at Allied Auto Works.

A while back, the Cash for Clunkers program was all over the CA news. Los Altos people could trade in their old vehicle for a new one that got better gas mileage and receive a government rebate.

A lot of Los Altos motorists had so-called clunkers that they wanted to keep. They're good commuters, grocery getters or toy haulers. They enjoy that fact that they're paid off, or soon will be. They would gladly like to keep their vehicles for 200,000 miles (320,000 kilometers) or more – as long as it's economical to do so.

There are plenty of Los Altos drivers whose vehicles are running after 150,000 or 200,000 miles (240,000 or 320,000 kilometers). We can learn from what they're doing to keep our own vehicles on the road in CA.

The Los Altos drivers of high-mileage cars often report a common denominator of never skipping an oil change.

That may sound a bit unsophisticated, but it's really not. First off, oil is the life blood of your vehicle's engine and it needs to be clean to properly lubricate. Skipping oil changes leads to clogged oil filters and sludge that is bad for your engine.

There's another reason the scheduled oil change is so important for Los Altos car owners. It's simple – a Allied Auto Works professional is going to be looking at your car. All of your fluid levels will be inspected and topped off so they won't get so low that damage can be done. If there is a significant fluid loss, let's use brake fluid as an example, your Allied Auto Works technician can look for the cause of the loss and find the problem before it leads to an accident or repair.

Your friendly and knowledgeable Allied Auto Works service advisor will also visually inspect your vehicle for worn belts and hoses, uneven tire wear, leaking shock absorbers and more. Problems get addressed before they lead to repairs that cost more than the car's worth.

Realistically, things are going to wear out as your vehicle gets older. On the way to 200,000 miles (320,000 kilometers) you'll go through several batteries, probably a couple of alternators and water pumps, a set of shocks and likely some brake rotors.

Of course, these things cost some money, but they are less than new vehicle payments in Los Altos. With proper service at Allied Auto Works and regular inspections, you'll keep surprise repairs to a minimum and more money in your wallet.

Til next time, this is

DUKE  here and things we don't expect happen to our vehicles. And let's face, no one really wants to spend money on an unexpected repair. But if you are putting off going to your vehicle repair facility because you're dreading bad news, you might just be putting off some good news.

There was one minivan driver who'd had the same van for years and never had a problem with the power sliding doors.  Then one day, the electrical switches in the door pillars stopped working.  The key fob would still open them, but the door switches wouldn't do a thing.

Of course, the van driver feared the worst: an electrical problem, a major computer failure, mice chewing up the wires.  So, he put off going into the repair facility for a couple of months.  One day, it was time for his regular oil change and the service advisor asked him if there was anything else going on with the van.  The owner mentioned the door problem but said he didn't want to spend a fortune on it.

He waited for his van, and it wasn't long before the service advisor came out with good news. The doors weren't working because a switch on the overhead console had been turned off.  (It was a safety feature to allow parents to disable them.) The owner had accidentally switched it when he was unloading the van.  It was the first thing the technician had checked. Flip the switch back and all was working as usual.

Another example? A mother was driving a minivan with her two kids inside on a hot day when she felt the front end shaking violently as she drove down the road. Fearing something major had broken in the van (and fearing for the safety of her kids), she pulled into a fast-food restaurant parking lot and started to look underneath to see if it was anything obvious she could see.

She couldn't see any broken parts, but she also didn't feel safe getting back in the van with her kids.  So, she called her local service facility and asked if they could send someone to look at it.  When the technician arrived, he took it for a test drive on the same road on which she'd described having the trouble.  Then he put her van up on the lift.  His conclusion?  Nothing was wrong with her van.  It was the street she was driving on.  Crews repairing it had left the surface full of potholes, and that was causing her rough ride.

Ultimately, what these two drivers feared would be an expensive trip to the shop resulted in each driver getting different news than they had expected.  One learned something new about his vehicle.  The other?  Well, the technician saw that her tires were badly worn and convinced her to get them replaced, perhaps preventing an accident and giving peace of mind for a mom with two kids.

So next time you OH NO!,  you might find out everything is ALL RIGHT!

Hi Cayenne here and as you know coonhounds have a nose for smells but did you ever think about the smell in your car and how it can keep you safe.......hmmmm let's take a sniff at this short but interesting topic!

Here's a travel tip that'll I'll bet you didn't know, and it might keep you safer...

The average American commuter in CA spends two and a half hours daily in their vehicle.

The government says 100,000 auto accidents yearly are caused by drivers who fall asleep at the wheel. (Aggressive driving is the number one traffic safety concern.)

So what does this have to do with how your vehicle smells while you're driving around Los Altos?

Well, which scent did you think makes drivers more alert?

Is it:

• A. Strawberry
• B. New Car
• C. Pine
• D. Warm Vanilla Breeze

It's C. Drivers are more alert and have less fatigue with pine scent in the vehicle, according to AroMetrics.

And, drivers were less angry with overall improved driving performance with strawberry and pine scents.

And you thought they just smelled nice. 

Well the nose knows!

Duke here and today we're going to bark about on-board diagnostics and the questions we hear from folks around bay area who need answers about diagnostic services.  First watch my video below!

 Want to know what diagnostics are, what's involved and what the benefits are?  Our clients really want to understand the value of diagnostic scans by a trained technician in the bay area.

These are valid concerns. If you don't understand something it's really hard to know its value. Let's start with some history.

Since 1996, all cars and light trucks in South bay, have been required to use a standardized diagnostic system to help repair technicians determine what's wrong with your vehicle. The diagnostic system works with the vehicle's Engine Control Module – the computer that controls many engine functions.

The computer monitors dozens of components and processes. Depending on what the sensors read, the computer will make adjustments to compensate for conditions and minor problems. When there is a condition that it can't adjust for, the computer will turn on the Check Engine light.

It is also called the 'service engine soon' light on some vehicles. The warning light signals you to get into your local service center so that the trouble code can be read and the problem can be fixed. Your service center will have a scan tool and powerful software that will help the technician diagnose the problem.

If you've searched for Check Engine light on the internet, you may have seen that you can buy an inexpensive scanner or go to an auto parts store to have the trouble code read to tell you exactly what's wrong.

That's a common myth. The code itself doesn't tell you what's broken. It starts you looking in the right place. It tells you what engine parameter is out of range – but it won't tell you what's wrong or how to fix it.

Let's say you think your daughter has a fever. You take her temperature and it reads 102 degrees F/38.9 degrees C. You've confirmed a fever, but you don't know what's causing it. Is it a 24 hour flu, an infection, appendicitis or leukemia? A fever is a symptom of all of these medical problems, but it takes a skilled physician's examination and additional diagnostic tests to find out what is actually causing the fever.

An example of a trouble code could be: P0133, which reads 'Bank 1 sensor 1 circuit slow response.' This means that the front oxygen sensor has a slow response time to changes in the air-fuel mix. If that's all you knew about cars, you would think your oxygen sensor was broken and would replace it. Now, it could be the oxygen sensor – but it could also be a bad or contaminated airflow sensor, exhaust leak, electrical problem, an intake manifold leak or any of a number of other things.

You can imagine a lot of oxygen sensors have been replaced because of that code. So the on-board diagnostics point the way to where the trouble lies, but it takes some skill and high-tech equipment to actually pinpoint the problem. The cheap scan tools that a consumer can buy do not have the ability to retrieve some of the operating history that's stored in the engine control computer. That history's very helpful in diagnosing the problem. Service centers like Allied Auto Works invest a lot of money in high-end diagnostic tools to help solve the mystery and get you back on the road as soon as possible without replacing a lot of parts that don't need replacing.

So, on-board diagnostics provide a powerful starting place for a highly-trained, well-equipped technician to get to the bottom of your problem. When your Check Engine light comes on, get it checked at Allied Auto Works. If the light burns steadily – don't panic. Get in to Allied Auto Works soon to have the engine scanned. A flashing Check Engine light means that there is a severe engine problem. Get in as soon as you can – waiting too long can lead to very expensive damage.

And try to not drive at high speed or tow or haul heavy loads with a flashing Check Engine light.

Make an appointment with Allied Auto Works to have your on board diagnostics analyzed.
