Nissan Altima 3.5 SE 2005 Model - Transmission Fluid Change

there is a plug in the bottom of the pan to drain the fluid. drain the fluid pull the bots on the pan pull down the pan take out the old filter put in the new and replace the pan. make sure the drain plug is tight and refill. make sure that you add the proper trans fluid and I would support a trans additive like lucas trans fix to help with the shifting.

here is a pic
