In between all this, some variations had a filter between the trans and oil pan, so you are not mistaken. Back home from the farm, FT145 is the Motorcraft, the NTZ assembly NTZ09-C09B I buy for $12.99. I dislike doing things on the cell.
The concept of eliminating the TP filter considers the 6.4L filter taking its place, so there is redundancy. The replacement block is a suitable choice if one doesn't want it up there and deal with it (problematic for breaking its hex when not using an impact). The cost of an occasional $12.99 filter that I don't have an issue removing, and it's primarily unseen, doesn't make the elimination vital to me. I have redundant filtering, something I don't see as a problem.
I've bought many parts for my Ford vehicles from ANWB, but sometimes their parts shipping is high, so I may go to Tasca or Lakeland Ford, although I prefer ANWB. Occasionally FordPartsGiant (not an actual Ford dealer, but a better shopping catalog) when their price is lower. They seem not to update their pricing as quickly as the Ford dealers. And RockAuto gets its share of Motorcraft purchases from me, too, although, over the last two years, I don't think they are getting the Ford wholesale deals they used to get. But with prices increasing and availability waning, both that and the shipping costs have become part of the equation for me. DieselFiltersOnline is local (like XDP), but I usually bulk price items and vehicles to reduce shipping costs.
