drain plug is under the trans. get under the car and you will see it. Take that off and drain the trans. when drained put the drain plug back in and torque it back down. Fill plug is on the front of the trans (under the intake). Its pretty easy to see. Get a funnel with a tube and stick it in the fill hole and fill all the way till it starts coming back out the fill hole (takes about 3 quars of trans fluid. Put the plug back in, tighten her up and you're done.
