Transmission fluid is the liquid that lubricates all of the moving parts located inside of the transmission. In automatic transmissions, the fluid is also a coolant and transmits power from the engine into the transmission. There are a number of fluids used depending on the type of transmission.
When it comes to changing your transmission fluid, you should make sure that it is getting changed at the recommended mileage. This is true for both manual and automatic transmissions. Most manufacturers recommend having the transmission fluid changed in a manual transmission every 30000 to 60000 miles. For heavy-duty use, changing the transmission fluid every 15000 miles
For automatic transmissions changing the transmission fluid varies. It can range from every 30000 miles to never changing it. Typically, the service interval for most automatic transmissions is from 60,000 to 100,000 miles. Changing it more will not do any harm.
If you do not change the transmission fluid in your vehicle you are essentially lubricating the transmission with contaminants including metal shavings. This shortens the life of the transmission and can result in a large payment to your mechanic if you end up needing to replace the transmission.
