Do You Really Need to Change the Transmission Fluid?

Yes, though how often this service should be performed varies by manufacturer and vehicle, and it's open to debate.

The manufacturer's maintenance schedule for many automatic transmissions doesn't call for fresh fluid until 100,000 miles or, with some Ford transmissions, even 150,000 miles. A lot of mechanics say that is too long and it should be done at least every 50,000 miles. Manual transmissions may be on a different schedule, so it's best to consult the maintenance schedule in the owner's manual.

Like other vital automotive fluids, transmission fluid deteriorates over time. Hard use — such as frequent stop-and-go city driving, hauling heavy loads, trailer towing — will accelerate the deterioration. That kind of driving raises the operating temperature of the transmission, and heat puts more strain on the transmission and the fluid, which helps facilitate gear shifts, cools the transmission and lubricates moving parts.

If you do a lot of driving under high-stress conditions, you should check the transmission level more often and have a repair shop check the condition of the fluid. Transmission fluid often is red but can come in other colors, and as it deteriorates it tends to turn darker. It may also acquire a burned odor that could indicate it needs to be changed or that the transmission is developing mechanical problems. Another indication it needs changing is dirt or other debris in the fluid. When you take your vehicle in for an oil change or other routine service, the repair facility may urge you to pay for a transmission-fluid change or flush. Even if they can show you that the fluid is darker than original, that might not mean you need fresh fluid right now. Step back, check the maintenance schedule in your owner's manual and see what the manufacturer recommends before you decide. This also will give you time to price shop.

Many repair shops use flush systems that force out the old fluid and pump in new fluid. Though that sounds good, some manufacturers say you shouldn't do that (Honda is one; there are others), so you need to know this before you agree to a flush. Look in your owner's manual. Some manufacturers, such as Honda, also call for their own type of transmission fluid and warn that using other types could cause damage. Moreover, some automatic transmissions have filters that should be cleaned or replaced when the fluid is changed. Make sure the repair facility is using the correct fluid and procedures for your vehicle.

If you have never changed the transmission fluid in your vehicle and have more than 100,000 miles on the odometer, should you change it now? We have seen mixed opinions on this, with some mechanics suggesting you should just leave well alone if you aren't having shifting problems. Adding fuel to this theory are stories about older transmissions failing shortly after they finally received fresh fluid. We have a hard time accepting that fresh fluid causes transmission failure, so our inclination would be to have it done if you're planning on keeping the vehicle a few years or longer. However, fresh fluid is not a cure for gears slipping, rough shifting or other mechanical problems, so don't expect a fluid change to be a magic elixir.

How To Properly Check and Fill Tires

While it may seem like a mundane task, inflating tires is much more crucial to your car than you may think, and it results in a safer and more economical experience on the road. Your vehicle's handling also will be greatly improved as the larger a tire's inflated footprint, the more responsive and comfier the ride balance will be.

Because it's National Tire Safety Week, it's the perfect time to check your car's tires.

Before starting

To find your tires' proper inflation level, look for a sticker on the driver-side doorjamb. It displays the vehicle weight restriction and tire information. The info is also found in the maintenance or car-care section of your vehicle’s owner's manual.

Don't refer to the sidewall markings on your tires, which in part specify the maximum tire pressure — not the recommended pressure.

Unless your tire is visibly flat, don't judge tire inflation just by looking at it; you have to use a tire pressure gauge to get the correct pounds per square inch reading. There are three types of tire-pressure gauges: digital, internal slide and dial. Prices range from $5 for a basic gauge to more than $30 for one that is digital, has an air-release button — or even talks. All will do the job, but you may want to consider the conditions in which you'll be using your gauge. "We've found that low-cost digital pressure gauges are very accurate and maintain the accuracy longer, but in extremely cold temperatures the gauge may not show up properly," said John Rastetter, Tire Rack's director of tire information services.



Tips for checking and filling your tires

Tire manufacturers suggest checking tires when they're cold for the most accurate reading. Outside temperatures can cause tire pressure to vary by as much as 1 psi per 10 degrees; higher temperatures mean higher psi readings. "Tires are black; what does black do? Attract heat," Rastetter said, noting the importance of finding a shady place to check and fill all four tires.

Temperature plays a huge part in tire psi, Rastetter said, adding that the most crucial time of year to check pressure is in fall and winter when days are shorter and average temperatures plummet.

Check your tires in the morning before going anywhere, because as soon as you get behind the wheel for an extended amount of time, psi will rise. Rastetter said that if you've been on the road a long time and notice higher psi in your tires, don't let the air out, as the increase in pressure has built up due to the warm, constantly-in-motion tires

What to do

1. Pull your car onto a level surface in the shade.
2. Remove dust caps from the tires' valve stems.
3. Using your tire gauge, firmly press the tip of the gauge straight on to the tire's valve stem for a brief moment.
4. The tire gauge should provide a psi reading; if the number seems unrealistically low or high — for example, 85 psi or 1 psi – you will need to repeat the previous step, ensuring that the tire gauge's tip is properly making contact with the valve stem.
5. If the tire gauge's recorded reading is higher than the manufacturer-recommended rating, press the gauge tip on the valve stem until you hear air leak out. Check the tire pressure again.
6. If the reading is lower than recommended, fill the tire with air by firmly pressing the air-hose tip onto the valve stem. You will hear air quietly enter the tire. If you hear air leaking or spraying out, you need to double-check that the connection between the air hose and the tire’s valve stem is secure.
7. When you think you've added or let out enough air, check the pressure a few times with the gauge.
8. Replace the valve dust caps. Rastetter emphasized the importance of keeping dust caps on during winter driving because if water gets into the valve stem and freezes inside the tire, it could cause a flat.

While you're at it, check your spare tire's pressure. You don't want to have a flat tire and then find out your replacement is flat, too.

Make these steps part of your routine. It will benefit your vehicle and your wallet.

How Long Does a Car Battery in a New Car Last?

Though battery problems are often associated with cold weather, Consumer Reports magazine says heat is a bigger enemy of car batteries and will take a bigger toll on performance and reserve capacity. The magazine recommends that vehicle owners in hotter parts of the country have their car battery tested after two years of ownership and then every year after. Those who live in colder areas can wait four years to test performance and capacity, and then every year after.

"Heat kills batteries," according to John Banta, a Consumer Reports project leader and part of the team that tests batteries for the magazine. "Many times in cold climates your battery fails to start your car on a below-freezing day. The reason this happens is that the heat of the past summers has weakened your battery. When you use it in the cold, the starter requires more electrical current to turn over the cold engine with its thickened oil."

Testing a battery's performance and reserve (or amp-hour) capacity is not just a matter of seeing whether it will hold a charge (or checking the electric eye found on some batteries to see if it is green), so testing is best done by an auto technician.

Does My Car Need Synthetic Oil?

If your car's owner's manual says it does, you do.

For many consumers, whether to spend extra money for synthetic oil for an oil change is a difficult question to answer.

Manufacturers of synthetic oil promise more miles and better performance when compared with conventional motor oil, but it comes at a higher cost — sometimes twice as much per oil change. Is it worth the extra money?

Typically, high-performance vehicles will be more likely to require synthetic oil, as will vehicles that have a turbocharged or supercharged engine. However, if your vehicle does not require synthetic oil, the choice is trickier - and there is no clear answer.

Synthetic oil generally resists breaking down for longer than conventional motor oil (typically 7,500 miles to 10,000 miles, sometimes up to 15,000 miles, as opposed to 3,000 miles to 7,500 miles for conventional oil). That makes the extra cost a wash, if you have half the number of oil changes, but each one costs you twice as much. Other touted benefits include cleaner engines, better flow in cold temperatures, better protection when it's hot outside and better performance with turbocharged engines.

There are also synthetic blends. As the name implies, these are blends of synthetic and conventional oils. They straddle a middle ground — they cost more than conventional oils but less than full synthetics, and are said to last longer than conventional oils but not quite as long as synthetics — but again, that's a hard number to pin down since manufacturers are vague with their claims. An independent testing lab we spoke with said that synthetics often didn't perform much better than conventional oils do.

Still, older engines may benefit from synthetics because it is less likely to form sludge.

If your car doesn't require synthetic oil you should perform a cost/benefit analysis, but that can be difficult to do due to vague claims made by manufacturers. There may be no reason to spend more on synthetic oil, except for peace of mind.

Avoiding Traffic Tickets

In an accompanying story, "Beat your Ticket", we give you some tips on beating your traffic ticket in court. We now have some overdue advice to offer: It's far easier to avoid getting tickets in the first place.

In this article, we'll tell you how to drive so the cops won't stop you. And we'll also tell you what to do and say if you are pulled over. Your behavior — and your attitude — could mean the difference between a ticket and a warning.

For answers to these questions, we talked to Walter Meyer, a teacher in a comedy traffic school and a freelance writer living in San Diego, Calif. He has collected a lot of information by studying the traffic laws and doing "ride-alongs" with traffic officers. But he has also gathered interesting anecdotal evidence from his students — harrowing accounts of traffic accidents, police stops and other driving mishaps.

Tire Safety: Check Your Tires for Wear and Tear

It only takes a penny to see if your tires are worn or losing tread. Examining your tires for wear and tear, along with checking tire pressure and alignment, are essential to ensuring your vehicle’s safety on the road and helping to improve gas mileage and performance. The non-profit Car Care Council recommends that motorists be car care aware and check tire condition and pressure regularly.

“The penny test is a simple, yet effective, way to check tire tread. If you see Lincoln’s head above the tread, you are ready for new tires,” said Rich White, executive director, Car Care Council. “Tires are critical to a vehicle’s handling and traction, and maintaining proper pressure is vitally important to vehicle safety. Underinflated tires are under stress and will wear unevenly, causing them to need to be replaced sooner. Routinely checking tire balance and wheel alignment reduces tire wear, improves handling, and increases fuel economy.”

Time to Change Your Vehicle’s Cabin Air Filter

Before winter sets in is a good time to check your cabin air filter, after it’s been working hard all spring, summer and fall. Cabin air filters clean the incoming air and remove allergens, and according to the Car Care Council, should be replaced every 12,000 to 15,000 miles, or per the owner’s manual.

The cabin air filter helps trap pollen, bacteria, dust and exhaust gases that may find their way into a vehicle’s air conditioning and heating and ventilation systems. The filter also prevents leaves, bugs and other debris from entering the heating, ventilating and air-conditioning (HVAC) system.

A dirty or clogged cabin air filter can cause musty odors in the vehicle and cause contaminants to become so concentrated in the cabin that passengers actually breathe in more fumes and particles when riding in the car compared to walking down the street. A restricted cabin air filter can also impair airflow in the HVAC system, possibly causing interior heating and cooling problems, important for staying comfortable this winter. Over time, the heater and air conditioner may also become damaged by corrosion.

A Resolution You Should Keep: Be Car Care Aware

To be car care aware, incorporate the following service interval schedule items as part of your New Year”s resolution:

• Perform monthly checks of tire pressure and the condition of tires, lights and windshield washer fluid. The vehicle should also be cleaned monthly.
• Every three months or per the owner”s manual, check the engine oil and filter, check the levels of other fluids including automatic transmission, power steering and brake, and check the battery and cables, belts and hoses. The exhaust and fuel filter should also be checked at this interval.
• Every six months or 6,000 miles, the chassis lubrication should be checked and windshield wipers should be replaced.
• Every 12 months or 12,000 miles, the brakes, spark plugs, coolant and steering and suspension should be checked.

Think You Know All About Distracted Driving?

Hands-free technologies might make it easier for motorists to text, talk on the phone, or even use Facebook while they drive, but new findings from the AAA Foundation for Traffic Safety show dangerous mental distractions exist even when drivers keep their hands on the wheel and their eyes on the road.  

The research found that as mental workload and distractions increase reaction time slows, brain function is compromised, drivers scan the road less and miss visual cues, potentially resulting in drivers not seeing items right in front of them including stop signs and pedestrians. This is the most comprehensive study of its kind to look at the mental distraction of drivers and arms AAA with evidence to appeal to the public to not use these voice-to-text features while their vehicle is in motion.

With a predicted five-fold increase in infotainment systems in new vehicles by 2018, AAA is calling for action as result of this landmark research. “There is a looming public safety crisis ahead with the future proliferation of these in-vehicle technologies,” said AAA President and CEO Robert L. Darbelnet. “It’s time to consider limiting new and potentially dangerous mental  distractions built into cars, particularly with the common public misperception that hands-free means risk-free.”

October Is Fall Car Care Month

Basic auto care goes a long way toward improving the safety and dependability of a vehicle. Whether you do it yourself or visit a trusted professional technician, take a look at these 10 Fall Car Care Month maintenance procedures to help make sure your car is operating at its best before winter arrives.

Fall Car Care Month in October is the ideal time to give your car some extra attention before harsh winter weather sets in. Taking a little time for auto care now can help you avoid the headaches of a costly emergency breakdown later.

1. Check all fluids, including engine oil, power steering, brake and transmission as well as windshield washer solvent and antifreeze/coolant.
2. Check the hoses and belts to make sure they are not cracked, brittle, frayed, loose or showing signs of excessive wear.
3. Check the battery and replace if necessary. Make sure the connection is clean, tight and corrosion-free.
4. Check the brake system annually and have the brake linings, rotors and drums inspected at each oil change.

Vehicle Warning Lights

Safety on the road is no accident. For example, when a warning light illuminates on a car’s dashboard, it is alerting you to a situation that requires your attention. While not all warning lights are a sign that disaster is imminent, no warning indicator should ever be ignored.

That’s the word from the experts at AAA, who encourage motorists to read their owner’s manual and know what each of the warning lights in their vehicle means. To help, they offer the following tips:

Oil Pressure Light

The oil pressure light is usually an oilcan symbol , although on older vehicles it may be a light with the word “OIL.” It comes on when there is a drop in engine oil pressure. Of all the warning lights, the oil pressure light indicates the greatest potential for serious mechanical damage.

If the oil pressure warning light comes on and stays on, pull off the road at the first safe opportunity, shut off the engine and call for assistance.

Engine Temperature Light

The engine temperature light is usually a thermometer symbol, although in older vehicles it may be a light displaying the word “TEMP.” It comes on when the engine temperature is above the recommended maximum. Unless the temperature is quickly brought under control, major engine damage is likely to occur.

Five Steps Towards Better Battery Behavior

Here’s hot news about your car battery that may seem surprising: It’s not so much the cold that gets it down as it is high heat. Heat causes battery fluid to evaporate, thus damaging the internal structure of the battery. That’s why it’s a good idea to check your battery as the seasons change from hotter to cooler or if you’ve been driving in a hot part of the country.

Another reason for shortened battery life is overcharging. That is, a malfunctioning component in the charging system, usually the voltage regulator, can allow too high a charging rate, leading to slow death for a battery.

Are Your Brakes Trying to Tell You Something?

If your brakes are trying to tell you something, you should pay attention. A properly operating brake system helps ensure safe vehicle control and operation and it should be checked immediately if you suspect any problems.

While an annual brake inspection is a good way to ensure brake safety, motorists should not ignore signs that their brakes need attention. Knowing the key warning signs that your brakes may need maintenance will go a long way toward keeping you and others safe on the road.

Motorists should look for the following warning signs that their brakes need to be inspected:

• Noise: screeching, grinding or clicking noises when applying the brakes.
• Pulling: vehicle pulls to one side while braking.
• Low Pedal: brake pedal nearly touches the floor before engaging.
• Hard Pedal: must apply extreme pressure to the pedal before brakes engage.
• Grabbing: brakes grab at the slightest touch to the pedal.
• Vibration: brake pedal vibrates or pulses, even under normal braking conditions.
• Light: brake light is illuminated on your vehicle’s dashboard.

Because brakes are a normal wear item on any vehicle, they will eventually need to be replaced. Factors that can affect brake wear include driving habits, operating conditions, vehicle type and the quality of the brake lining material. Be sure to avoid letting brakes get to the ‘metal-to-metal’ point as that can mean expensive rotor or drum replacement.
