How do I change the transmission fluid in a Kia Rio?

I recently purchased a Kia Rio and noticed that the transmission fluid looks dirty. How often should I change it and what is the recommended procedure?

You should change your transmission fluid every 30,000 miles or every 3 years, whichever comes first. First, make sure the car is on a level surface and remove the transmission drain plug to drain the old fluid. Then, remove the transmission filter and replace it with a new one. Finally, refill the transmission with the recommended fluid and check for leaks.

I suggest consulting your owner's manual for the specific recommended procedure for your Kia Rio. Generally, you should change the transmission fluid every 30,000 miles or every 3 years. Be sure to use the recommended fluid and replace the filter as well.
