[Focus Is Art]

There is no filter.

1) get a 8mm(or 10mm don't remember) Hex key
2) there is 2 plug on the tranny, one facing the front(fill plug) and one facing the rear(drain plug). Make you lose the fill plug.
3) Pull the drain plug and release the oil.
4) get a funnel attach a 3ft tube with it.
5) close drain plug and open fill plug
6) fill 2.1L of oil using the funnel(or keep filling till over load on a level surface)
7) close fill plug.
done.

I personally don't like ford tranny oil but it is your choice.
