What You Need to Know About Transmission Fluid Changes

The transmission fluid is a very important part of your engine. Without the proper levels of transmission fluid in your car, you will experience all kinds of problems. Additionally, if the transmission fluid is not changed periodically, you will experience problems. Some people have come to believe that transmission fluid is something that never needs to be replaced. While it does not need to be changed as often as oil does, it is still very important to check and maintain clean fluids in your car.

The schedule by which to change your transmission fluid will differ between manual and automatic transmissions. Every 30,000 miles is a very good suggestion for all drivers regardless of whether they own an automatic, or manual. Those who are heavy manual transmission drivers are suggested to get a change every 15,000 miles. Intervals for automatic cars goes up as high as 100,000 miles between changes. There are reasons why you would want to change the transmission fluid more often than that. Because of the long length of this kind of fluid in automatic cars, some believe it never needs to be changed. This is incorrect and can lead to costly repairs.

The problem that you will run into with it is the build-up of metal particles. These particles will float through your engine and build up in different components causing you other kinds of problems. The money you saved on not changing the transmission fluid will seem like a drop in the bucket compared with the price of replacing the entire transmission later on. This can be avoided by simply changing the fluid regularly. Keep in mind, automatic transmissions run hotter than a manual does. For this reason, transmission fluid can actually be broken down over time. This will cause the fluid to not lubricate as well which will lead to mechanical problems.

Those thinking about changing their own transmission fluid may want to reconsider as it is not as simple as an oil change. With regular oil, you can utilize gravity to easily drain the car of any oil it contains. It is much more viscous and requires a transmission flusher to get everything out. It is recommended to bring in your car to get this kind of fluid change in order to make sure all metal shavings in the old fluid will be washed away. Not removing all of the fluid can cause you just as many problems as if you did nothing.

Those looking to check the levels between maintenance visits simply need to know what they are looking for. Keep in mind, most manual engines will not come with a dipstick to help you check the fluid level. Those with an automatic transmission will want to either have their mechanic point out the right dipstick, or check the owner's manual. Many will confuse the crankcase dipstick with that of the transmission. Keep in mind, generally the only reason why the fluid level will be low is if there is a leak. If you check your level and it is low, you need to get your mechanic to check out the transmission right away.

When Should You Visit a Transmission Repair Specialist?

Most people drive their cars every day but still don't know how they work. Sometimes drivers will even ignore obvious problems with their vehicles, hoping they will go away on their own or that it isn't something serious. Only when the car stops working altogether do they visit a mechanic in a panic! Issues with a car's transmission can mean serious problems down the road if they are not attended to quickly.

In layman's terms, a transmission transfers the power created by the engine to the drive line and wheels: this can be done either manually (as with a stick shift) or automatically.

Here are some of the symptoms of transmission problems and how to know when it's time to visit a transmission repair specialist.

-- Problems shifting gears: since the transmission's job is to keep up the momentum of the car by shifting gears, it stands to reason that any problems with gear change may be stemming from the transmission. The symptoms could be an unusual noise made by the transmission during a shift, or, if you drive a stick, it may not glide smoothly between gears.

-- The car makes a jerking movement or the engine surges at inopportune times. The jerking movement could indicate that the engine's power is not being smoothly transferred when a shift needs to occur.

-- Transmission fluid is leaking. Transmission fluid acts as a lubricant for all of the moving parts inside your car's transmission. Just as the engine cannot run right without oil, the transmission will not work right without fluid. Transmission fluid is generally reddish in color, so if you see any on the ground under your chassis, get help right away before a costly disaster happens.

-- The car won't move. If your car starts up ok, it just refuses to move, the problem is likely to be with the transmission. You'll need to have it towed to a shop where their mechanics can advise you on what to do next.

All car drivers should have a working knowledge of how their vehicle works and what the symptoms are for certain problems that may arise. If you suspect your transmission is to blame, take it to a mechanic: it does not necessarily mean it has to be replaced. The problem may just be a minor one; but one thing's for sure: transmissions do not fix themselves!
