How do you change manual transmission fluid on a Kia Rio?

To change the manual Transmission Fluid on a Kia Rio, first, ensure the vehicle is on a level surface and securely raised. Remove the fill plug on the transmission and then the drain plug to allow the old fluid to drain completely. Once drained, replace the drain plug, and use a pump to add new transmission fluid through the fill plug until it reaches the appropriate level. Finally, replace the fill plug securely.
