Answer 1

To change the transmission oil on a 2009 Kia Optima, first ensure the vehicle is on a level surface and securely raised. Remove the transmission drain plug and allow the old oil to fully drain out, then replace the plug. Next, remove the transmission fill plug and use a funnel to add the new Transmission Fluid, ensuring you use the correct type specified in your owner’s manual. Finally, start the engine and cycle through the gears to circulate the fluid, checking the level and topping off if necessary.
