If your gearbox overheats, it begins producing debris, and that will start wearing down parts inside the gear case. Some older models may even use motor oil or gear oil. If your car has a continuously variable transmission CVT or a dual clutch, it will probably use synthetic transmission fluid. This type of fluid is designed to have better resistance to heat, cold and oxidation.
It costs more than organically based fluids but also lasts longer. Your service intervals depend upon your type of fluid, car usage and vehicle. Like most types of automobile fluids, transmission fluid has an expiration date, so you need to pay attention to when you last had it changed. Transmission fluid can last anywhere from 30, miles to as much as , miles — with synthetic fluid lasting the longest. But an automatic transmission will typically need to have the fluid changed more frequently than a manual transmission because — as mentioned above — an automatic generates more heat.
Keep in mind, however, that these are just guidelines. If you are using your vehicle in conditions that put more demands on the transmission — such as towing vehicles or heavy equipment, driving in a city while changing gears frequently or driving in difficult weather conditions hello, Ohio winters!
This can lead to your transmission overheating and failing. If you are driving around with either very old or not enough transmission fluid or worse still, both , you are accelerating the wear and damage on components within your transmission. Taking the time to change it out when necessary could save you loads of time and money in the end by extending the lifespan of your transmission. Just when you should change out your transmission fluid will vary depending on what kind of transmission you have, what vehicle you drive, where you drive, how you drive, and how much your drive.
But for a very rough estimate, for an automatic transmission , you ought to change your fluid every 50,, kms. The Automatic Transmission Rebuilders Association suggests every 50, kms or every two years. For manual transmissions , you should change the fluid about every 50,, kms, however, under intense use, some manufacturers suggest changing it as often as every 25, kms. The reason for the difference between automatic and manual transmissions is because they take different fluids.
Automatic transmissions take —get this— automatic transmission fluid. For manuals, it is a bit more complicated. They might take any of a variety of oils: regular motor oil, heavyweight hypoid gear oil, or even automatic transmission fluid in some cases. To change out your transmission fluid, first let your car idle for a few minutes. After turning your ignition off, raise and secure the vehicle. Lay down at least a two-gallon catch pan, then carefully remove the bolts from one side of the transmission pan and then the other bolts, allowing the pan to tilt and drain.
After that, remove the old transmission filter and O-ring. The filter contains fluid, so keep the drain pan underneath. Install the new transmission filter, and make sure that the O-ring is in the appropriate place. Attach the new gasket to the pan with oil-soluble grease — not gasket sealer or adhesive. Screw in all the fasteners finger-tight. Torque the pan bolts to spec in a spiral pattern starting at the center. Maximum torque is often about 12 pounds per foot. Then, lower your automobile and fill the transmission with the recommended amount of fluid.
Finally, turn your engine on to check for leaks. As you can see, changing your transmission fluid is quite involved. The evolution of transmissions has made these machines and systems increasingly complex. Overall a change is advised every If you want to check if your transmission fluid is still in a good condition, you can check this on a few factors:.
When you have decided you transmission fluid is ready for a change, you have two options to choose from on how to do this. The first one is by flushing out the old fluid. This is done by pumping in new fluid and thereby forcing out the old fluid. The advantage of flushing is that flushes out all the debris and metal shavings that was gathered by the fluid.
However, if your old transmission fluid is dark and burnt, it is better to drain it instead of flushing. This because flushing could cause the burnt fluid to get the valve body clogged up.
When you want to change your transmission fluid by draining, the pan will be drained and the filter replaced.
