How often should the transmission fluid be changed in a Kia Rio?

I recently bought a used Kia Rio and I'm not sure when the previous owner changed the transmission fluid. How often should I change the transmission fluid in my Kia Rio to maintain good performance and avoid potential issues?

It is recommended to change the transmission fluid every 60,000 miles or every 5 years, whichever comes first. However, if you frequently drive in severe conditions such as heavy traffic or towing, it is recommended to change it every 30,000 miles or every 2 years.

As a Kia technician, I have seen that neglecting transmission fluid changes can lead to expensive transmission issues. It's best to follow the manufacturer's recommendations to maintain the longevity of your vehicle.

While the owner's manual recommends changing the transmission fluid every 60,000 miles, some Kia Rio owners have reported issues with their transmission at around 50,000 miles. It's better to err on the side of caution and change the fluid at 50,000 miles to prevent potential problems.
