Transmission fluid is essential for the inner working of our car. It is needed to lubricate the complex transmission assembly. Other than lubricating the transmission system, the fluid also works as coolant, because heat is generated by metal surfaces that rub one another. Lubrication ensures smooth transfer of power to the wheels. Highly efficient transmission ensures that fuel can be saved, because the car will run faster with less amount of effort. Automatic and manual transmission require the fluid. Based on the owner’s manual and other guidelines, car owners should change the fluid regularly. Heat exposure could cause the transmission fluid to break down slowly. Contaminants will also accummulate in transmission system and we should make sure that these contaminants can be removed as soon as possible. It is obviously not a good thing to lubricate our transmission system with fluid that contains abrasive metal particles. Many cars die prematurely due to serious transmission issues that can be prevented by regular oil changes.

It is important to check your owner’s manual for any specific recommendation about the transmission fluid. Depending on the car type, the recommendation can be quite different. The manual may say they we need to change the fluid for manual transmission every 30,000 miles or more. However, cars with automatic transmission may need to change every 60,000 to 100,000 miles. Even if we are still far away from the actual replacement of transmission fluid, we will need to check the fluid level. Many newer cars don’t have dipstick for the transmission fluid, so we may need to ask mechanics to check the level. The mechanic may drain the fluid, to check visually whether it contains high amount of particulate and gunk. If the fluid still looks relatively clean, it could be used again. Fluid for automatic transmission has distinct burnt smell when it has gone bad. With proper examination, the decision whether we should or shouldn’t change the transmission fluid should be quite simple.

If the fluid level seems to become too low, it’s a good idea to check whether there’s a leakage. While in garage, we should check whether there’s wet or dark spots. This should be a good indication that we need to check our car. We may easily see where the source of the leak from the position of our car. The transmission system will start to break down when the fluid level is too low. We should know that transmission and engine fluids are different. The former doesn’t burn when exposed to high temperature. So, when the transmission fluid level is too low, it is more likely that we have some leakage. In many cases, repairing the leakage should be quite easy to do. Drips of fluid can be prevented by performing simple repair. We should ask the mechanic about the best way to properly check for any kind of leakage while we are at home. This will ensure that our car will always be in a good condition, because transmission fluid is very important for our car.
