Drain the
transmission fluid through the drain plug on the bottom of the pan. The
plug should be a 14mm. Next you should remove the dip stick, then the
dip stick tube. The tube bolts to the side of the engine, near the
bottom of the engine. The bolt is a 14mm. Next remove the drain pan by
removing the bolts (of course). The bolts are 10mm. Remove all of the
bolts except maybe 4. Loosen those, then pry the pan loose. There will
be some fluid left in the pan after draining so this will prevent you
from getting fluid all over you. Use a screwdriver to pry the tubes at
the ends, where the tubes bend. Be very careful not to bend the tubes.
Without the tubes, your transmission will be useless.

Make
sure to remember where the tubes go. You may have to get one end loose,
then rotate the tube back-and-forth, while pulling down on the tube, to
get it loose. After you remove the tubes, pry the tabs holding the wire
to the filter, then move the wire to the side. Then remove the bolts
holding the filter to the transmission. They are 8mm.

Once you
have removed the bolts, pry loose the filter. A good bit of fluid will
run out from the transmission so have that drain pan in place.
(click picture for larger picture) All you
have to do now is scrape all your old gasket material from the place
where the filter, and the pan bolt up. Install everything in reverse
order of removal. You might want to install a new O-ring on the dipstick
tube. (see picture) 
It
took me about 4 quarts of transmission fluid to refill the transmission.
Chiltons calls for 2 1/2 quarts.
