Of course, you can go to your favorite auto service facility and have a trans flush and refill done. Many shops today have a machine for this purpose, but you've got to be sure of what you're getting. Some quick-lube places will just attach the machine to a cooler line, exchange the fluid, and call it done.

Some car manufacturers recommend getting a fluid change every 100,000 or even 150,000 miles, but that is far too long when you think about it. The average driver logs about 12,000 to 15,000 miles per year, so if you were to get a fluid change every 100,000 miles, you’d end up servicing your transmission once every 6.5-8.5 years. That’s 10-12.5 years if you service it every 150,000 miles. Who knows what condition the fluid will be like then!

To find out what type of transmission fluid your vehicle uses, check out this article about different types of transmission fluid. Lastly, how often you get your transmission fluid changed depends on whether you flush your entire system or just drain the pan. Your transmission may hold 15 to 20 quarts of fluid or more! If you simply drain the transmission fluid pan you will only change 3-5 quarts leaving lots of dirty fluid still in the system.

DIY transmission fluid and filter changes. Even those of us who change our own oil often cringe at the prospect of draining ATF. Because many transmission pans don't have drain plugs, changing the fluid can be a messy proposition – the entire pan must be removed.

That’s why it’s recommended to get a fluid change every 30,000 to 60,000 miles, or once every 2 to 4 years. This is the optimal schedule for the average driver and will allow your transmission to run on healthy fluid constantly, which ultimately means a longer lasting and more efficient transmission.

But today there's a subtle discord in the usual harmony, a blip on your vehicular radar, a bad vibe in your mechanical karma. Shifts seem oddly late and soft. Later, as you pull into the drive, you sense something peculiar. Letting your car idle, you pull the dipstick out of your auto transmission. Fresh automatic transmission fluid (ATF) is bright red and has a distinct petroleum smell. Your dipstick shows a low level, is the color of institutional linoleum and smells like the bottom of a barbecue pit after a biker wedding.

In automatic transmissions/transaxles, the recommended service interval is about every 30,000 miles or 30 months. (Check your owner's manual or service manual for your car's specifics.) The automatic transmission fluid (ATF) should be changed sooner if its dipstick reveals dark or burnt-smelling fluid.

If you can garner some initial patience, learning how to change automatic transmission fluid will only benefit you in the long run. More importantly, you’ll need an automatic transmission filter kit; they normally contain a gasket for the pan in addition to the new transmission filter and its O-ring.

How often you should get your transmission fluid changed depends on a few different factors including the make and model of your car, the type of transmission it has installed, the type of driving you do and what sort of maintenance you do on your transmission.
