From what I have read, auto parts stores do sell a friction modifier, so you don't have to depend on Ford.
If you are changing fluid altogether, use Mobile 1, or Valvoline LS. Both already have it in there. (Make sure you read the bottles)
Ditto, the Mobil 1 LS fluid is good to go right out of the bottle, no need to mix additive, although you will need another auto loan to buy the stuff
