Do you want to really scare one of your friends who own a car? Tell them that it sounds like they are having problems with their transmission. Your car is probably the second biggest asset you will ever own after your mortgage and having problems with the transmission of your car is a very serious problem. Anything you can do in order to prevent damage to your transmission can help to prolong the life of your car. One option is to make it a point to have a transmission repair service center perform a transmission fluid change. It seems like most people have accepted the fact that it is important to have the oil in your car changed periodically. They may stretch out how often this is done, but they do make sure it gets done. However, most people are not aware of the fact that you also need to have the transmission fluid changed in your car. You do not have to do it as often as you need to change the oil, but it is still pretty critical that you do it.
A general guideline for how often you have to change the transmission fluid is approximately every 30,000 miles. However, this could be higher or lower depending upon how the car is used. Some manual transmissions really should have their transmission fluid changed about every 15,000 miles. However, there are actually some cars being build right now with automatic transmissions that can go up to 100,000 miles before this fluid is changed. But do not let this long life fool you. It is easy to forget that this fluid needs to be changed since it lasts so long, but it is still important to keep track of this and change the fluid.
The biggest problem with not getting the fluids changed is that there are very small metal particles that develop over time. As these particles flow through the system, they can begin to cause problems with your engine. Another thing that happens is that in time, the fluid begins to break down. This means that some parts of the engine would not be properly lubricated, which means mechanical problems can develop.
The best way to prevent problems is to regularly change the fluid. If it does not seem like it is worth the cost, find someone who had to get a new transmission and ask them how much it cost. Then compare that to the amount of money the service station would charge you to complete this process. There really is no comparison.
When you decide to have the fluid changed, you need to know that it is not as easy as changing the oil in your car. When you change the oil, gravity causes all of the old oil to flow through the engine into your drip pan. Gravity causes this to happen. The transmission fluid does not work like this; it will need to be flushed out. Only doing a partial change of the fluid and not getting all of the old fluid out can actually cause more problems than if you did not change any of it.
