First of all that AW-4 doesn't have a filter. It has a screen. The way
I did a complete change was by removing the upper transmission cooling
line at the radiator (the return line, make sure you use a flare nut
wrench!). Clamp a 3' piece of 3/4 hose on the nipple on the radiator.
Get yourself 2 -1 gal. Plastic milk containers with screw caps (or any
opaque container gallon size), and another container that will hold at
least 2 gallons. The 5-gallon plastic containers that the Chinese
restraints use for cooking oil are great. You can usually find them in
their garbage. Cut the side out to make a drain pan. Remove the drain
plug and drain out the fluid. It should be around 2 1/2 qts. Fill the
transmission with the same amount you took out. Now place the hose
into the other milk jug, start the car (it helps if you have another
person to start and stop the car), and fill the jug to about 3 qts.
Stop the car and add 3 quarts repeat this until you use about 8 or
nine quarts, or when the color of the two fluids look the same. You
will have completely changed the fluid. I use Mobil 1 synthetic. I
also use it in the transfer case.
