how often should you change your transmission fluid

Transmission fluid is a slippery liquid that acts as a lubricant for all of the moving parts inside your transmission. In an automatic transmission, this fluid also serves as a coolant and a viscous fluid that transmits power from the engine to the transmission.

How often do you have to change transmission fluid?

Manual Transmissions: Most vehicle manufacturers recommend a transmission fluid change between every 30,000 to 60,000 miles. The problem is fluid contamination which occurs over time as the synchronizers, bearings and gears in the transmission wear out. The resulting metal particles then float around in the lubricant. Oil that contains microscopic particles of metal does not lubricate as well as clean oil. So if these contaminants are not drained out, they will shorten the life of your transmission.
Automatic Transmissions: A fluid change for automatic transmissions can vary from every 30,000 miles to possibly never. Because more heat is generated in an automatic transmission, automatic transmission fluid actually degrades and breaks down with use. It also becomes contaminated with worn bits of the transmission.

Is there any Transmission Service required between fluid change intervals?

The typical transmission service interval is 60,000 to 100,000 miles. Don't forget to check the fluid level between the fluid change intervals. Letting your car run low on transmission fluid can cause the transmission to shift improperly—or not at all. It also can harm the internal parts of your transmission, which are not being properly lubricated. Unfortunately, you may not hear any noises or have other clues that your transmission is low on fluid until it's too late.

A Word to the Wise: Changing transmission fluid at the correct service interval maintains the investment you have made in your vehicle.
