How do you change 2003 lancer transmission fluid?

To change the Transmission Fluid in a 2003 Mitsubishi Lancer, first, ensure the vehicle is on a level surface and securely lifted. Remove the transmission fluid drain plug and let the old fluid fully drain into a catch pan. Replace the drain plug, then use a funnel to refill the transmission with new fluid through the dipstick tube, checking the level as you go. Finally, start the engine, let it run for a few minutes, and check the fluid level again, adding more if necessary.
