I also went over my intended drain interval of 15k to 19k due to work ect. I did it this evening when I came home (got off early) and forgot how easy it is to do. After seeing Jeffs blackstone report of his Mercon SP (here on the board somewhere) there is no way the add pack is anywhere near used up at 30k let alone at 15k. I know you are only changing half the fluid, but I did change all of the fluid at 30k. The add pack in this FULL SYNTHETIC FLUID would probably go 70-80k, so by adding roughly close to half new fluid every 15k should be more than sufficient. The majority of the Ford dealerships (at least in my area) are just draining/refilling the pan at 30K. No external filter or flush. They also get $80 for the external filter and o-ring. Needless to say I don't get mine there.
The internal filter or "porch screen" in a plastic housing is a waste of time til at least 60k. I ordered one for the initial 30k flush and upon opening the box and looking at it, said to myself I'll wait til the 60k service.

I am going to just drain the pan and change the external every 15k. I will drop the pan every 60k and change the porch screen and have a look see whats inside the pan itself. I think the initial 30k flush is probably a good thing as far as removing all the fluid after a significant break in period. Even at the 30k mark I put the old and new fluid in a clear bottle next to each other and you couldn't tell the 2 apart. (I know its not very scientific, but if it looks like a duck and smells like a duck, its probably a duck) The external filter looked about the same at the 30k mark as it did this time at 19k, which tells me they should have been using them along time ago, due to the exceptional filtering job it does.
