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:

Replacing Your Car’s Timing Belt

Knowing When To Change A Timing Belt

Changing a timing belt on your vehicle can be a very time consuming. This is due to the fact that there are a lot of components under your hood that must be removed before you can even get to your vehicle’s timing belt. This is why it is best to change a timing belt at the same time that you are planning on doing other repairs and maintenance practices to your vehicle such as putting on a replacement water pump or changing belts like the serpentine, air conditioner or water pump belt.
Timing belts tend to begin breaking down at around 60,000 miles. You will notice the power to your vehicle begin to slow down, the fuel efficiency of your vehicle can be affected as well as your vehicle showing signs of working harder.
How To Change A Timing Belt or Timing Chain
Different vehicles have different patterns for changing a timing belt or timing chain. The best thing to do when you want to change the timing belt is to look over your owner’s manual that is specific for your make and model vehicle. You can also purchase an automobile repair manual that is designed specifically for the needs of your automobile at any automotive repair shop in your local area.
The basics to changing a timing belt on the vehicle however are pretty much uniform. The steps to do this are as follows:
Step 1. Before you can replace the timing belt on any vehicle it is a good idea to let the vehicle sit overnight so that the engine is completely cool and there is a reduced chance of experiencing serious burns from the engine.
Step 2. As it is with most vehicle repairs you must first disconnect any power supply to the vehicle. This means that the battery cables must be removed from the battery terminal and tied back so that there is no risk of them touching the posts or other parts of the vehicle while working.
Step 3. Place blocks in front and behind the wheels of your vehicle so that there is not chance of the vehicle rolling and accidentally causing injuries to you or others who may be around.
You will now need to remove any obstructions that may be in the way of getting to your timing belt. This includes:
Step 4. Make sure that the air intake assembly to your vehicle is completely removed.
Step 5. Locate the pulley that powers the supply to your water pump if this is in the way on your vehicle. You will need to loosen the bolt holding this pulley in place.
Step 6. For some vehicles it may be necessary to do the same for other equipment such as the power steering pump. This will require you to loosen the bolt and remove the belt that is around the pulley. You can then unbolt the power steering pump and move it out of your way.
Step 7. Line up the mark on your crankshaft pulley to the O that is on the timing scale with a large wrench. You can find the timing scale molded on your vehicle engine block.
Step 8. Using the right sized socket you will have to removed the bolts that are holding the timing belt cover on. When you have the bolts removed you can then pull off the timing belt cover.
Step 9. Inspect the timing belt tensioned bearings for any looseness or noise. If these problems exist you will need to replace the timing belt tensioned bearings as well.
Step 10. Locate your camshaft and check to makes sure there are no leaks in the crankshaft or camshaft seals. If you do notice leaking this could be an early sign that there will be premature failure for your new timing belt. It is best to replace these seals now instead of waiting for bigger problems and the chance of having to do all of this work again.
Step 11. For most vehicle makes and models you should now be able to locate the timing belt. Make sure that all timing marks on your belt are properly lined up. Loosen the timing belt tensioned and you will then be able to remove the timing belt very easily. Make sure that the camshaft and crankshaft for your vehicle’s engine are secured and that they do not move while your timing belt is off of your vehicle.
Step 12. Place your new timing belt on the same way that you removed it. Make any tension adjustments to the timing belt as necessary. Inspect the new belt to make sure that it is fitting over the teeth for the timing sprockets correctly. Makes sure that you do not over tighten the belt.
Step 13. When replacing the timing belt cover install a new gasket to seal the cover correctly. Do not use an old gasket as this will not seal properly.
Step 14. If you had to remove any pumps at the beginning of this project you will now have to hook them back up again. This includes the water pump, power steering pump as well as any other accessories that may have gotten in the way at the beginning of this project.
Step 15. Visually inspect all timing marks to make sure that they are still aligned correctly.
Step 16. Reinstall your vehicle’s air intake assembly that was removed in the beginning.
Step 17. Reconnect your vehicle’s battery. Make sure that there is no corrosion around the posts or the battery cables while you are at this step.
Step 18. Turn on your vehicle and look for any problem areas such as leaks that there may be prior to driving your vehicle. Do not hesitate or postpone any repairs that may be needed.
