If you can't trust them with that...why trust them at all?
Joe if you can wait until I have a free weekend, take a drive up my way with mercon V, some beer and steak for the grill and we will do it in my garage then cook out after. =)
Friends don't let friends buy "whatever" brand filters.
Motorcraft (#F6AZ7A098A according to Rock Auto) is your best bet for a transmission filter. You don't change it enough to justify getting a cheap filter.
I usually use motorcraft filters too. Super special rear diff?? lol
