How to change transmission oil on lancer car?

To change the transmission oil on a Lancer, first, ensure the vehicle is on a level surface and securely lifted. Remove the transmission drain plug to let the old oil drain completely, then replace the plug and remove the fill plug. Pour the new transmission oil into the fill hole until it reaches the proper level, then replace the fill plug. Always consult your owner's manual for the specific oil type and capacity for your model.
