Automatic Transmission Failure: How to Check Fluid and Prevent Costly Breakdowns

No two words strike fear into the hearts of those of us who are not mechanically inclined like the words: transmission failure.

Checking my engine oil may be the extent of my automotive expertise, but I’ve learned that having a faulty automatic transmission can mean almost certain death for a vehicle. For most cars, particularly those that are getting on in life, the cost of replacing an automatic transmission exceeds the value of the entire vehicle – rather like totaling your car.

Fortunately, transmission failure does not happen randomly; indeed, catching the early signs of transmission trouble is easy if you know what to look for. Here are a few things you can do to make sure your automatic transmission doesn’t cause premature car death.

1) Own cars with manual transmissions. Ok, so this isn’t exactly a solution to maintaining an automatic transmission, but car owners should be aware of the differences between manual (standard) and automatic transmissions. Manual transmissions (or “stick shifts”) are more energy efficient than automatics, but more importantly, they have far fewer moving parts – which means way less maintenance and risk of part failure. Sure, you can talk on your cell phone, keep the kids in the backseat from fighting and drink your coffee simultaneously while driving an automatic, but a manual transmission will never conk out like an automatic.

2) Check automatic transmission fluid (ATF) regularly. This is really not hard – no harder than checking your oil levels. If you’re unsure exactly which dipstick is for the ATF or what to look for once you find it, watch this short video on how to check your car’s ATF. If you’re still unsure, there’s a great little auto repair shop on Fulton Street where the mechanics would be happy to show you.

Keep in mind, you’re looking for two things: level and color. The fluid mark needs to hit between the low and high marks, and it should be nice and red.

3) Change your ATF regularly! Although it may seem like this step would naturally follow the previous step, there are those of us (like me) who need the reminder. If your transmission fluid is dark, brown or muddy-colored, it’s time for a professional to take a peek and probably perform a transmission fluid flush.

Please think twice before taking your car to a drive-through service for transmission fluid flushes. There are many reasons why these places don’t always offer the best service for your money, but a certified AAA repair shop like Cars for Keeps will certainly give you a more thorough flush and overall checkup.

4) Listen to your car. As we’ve said here before, your car will usually tell you something is wrong before a major breakdown. Any out of the ordinary noises could be suspect, so bring your car in for inspection if you hear anything unusual. J.B. Herbert gives us a few pointers here:

When To Replace Your Timing Belt

Timing belt replacement is the “must-do” service operation which every car owner should know about. Along with that knowledge, we should be aware of whether our engine is considered an interference engine or not. These two bits of information can, at a minimum, save us from unexpected breakdown and in the extreme can help us avoid thousands of dollars in repairs.
Without getting too technical, the synchronization between two internal engine parts (the crank and cam shafts) is accomplished with the help of the timing belt. In the process of these two parts moving the valves open and close in close proximity to the pistons. This constitutes an interference engine, because if the timing belt jumps a tooth on the sprocket on which it rides or the belt fails altogether the valves and pistons will “interfere” with each other.

This collision will cause major damage to the engine. The repair bill will, on older vehicles, often exceed the value of the car. On the other hand, a car whose engine is not configured this way will simply lose power or will not start. While this might be more desirable than facing huge repair costs, it is something that is better avoided if possible.

The motivation for preemptive replacement of the timing belt is obvious. But how do you know when to replace it? There is always the owner’s manual which will indicate mileage of anywhere from 50,000 to 90,000 miles. For a comprehensive list of timing belt service intervals and the type of engine (interference or not) check out About.com.

Some other considerations relative to timing belt replacement are:

1) Is the vehicle leaking any type of fluid that might degrade the belt, if so disregard the suggested replacement interval and replace the belt ASAP as well as repair the leak;

2) Do you know the repair history of the vehicle if it is not verifiable err on the side of safety and replace the belt;

3) Timing belt replacement can be labor intensive. Since the water pump is usually accessed in the same operation you might consider replacing the pump at the same time even if it doesn’t leak. You will save on labor and possibly prevent a pump replacement later on that will also necessitate the belt to be replaced again;

4) To avoid subsequent failure consider replacing sprockets and tensioners that are part of the timing belt system. All components are sometimes sold as a kit and can be less expensive than purchasing them individually.

All service intervals should be followed in order to protect your investment and maintain the integrity of your warranty. In the case of the timing belt, it just makes sense.
