For some reason Ford uses chicken wire grade filters - actually screens. I would go to NAPA and ask to see a filter. To me changing chicken wire is an exercise in uselessness. But I heartily endorse draining the torque converter. When dinosaurs ruled the earth and I did a stint at a Plymouth agency, I discovered torque converters drain real slow. I hope yours drains faster than the old MoPar A727 and A904 did. Ford C4 and C6 Converters drained slow as well.
17 quarts is more than four gallons. Prepare yourself! I used to see if I could leave a drain pan in llace then back the finished job away from the filled drain pan. Depends on crossmember and tie rod clearance. Dragging a pan from beneath a rig meant slopping drained oil all over. And overfilling a transmission is a no-no.
Hope this helps
