How do you change the automatic transaxle fluid on a Kia rio?

To change the automatic transaxle fluid on a Kia Rio, first ensure the vehicle is on a level surface and the engine is warm. Remove the Transmission Fluid drain plug to drain the old fluid into a suitable container. Replace the drain plug, then use a funnel to refill the transmission with new fluid through the dipstick tube, ensuring you use the recommended fluid type. Finally, start the engine and let it run for a few minutes, checking the fluid level and topping off as necessary.
