I got a letter from Ford today saying that the transmission in my '05 Limited had been "filled with a fluid formulation that, over time, may cause delayed/harsh reverse engagements". Ford offers to have the dealer install a bottle of additive to correct the formulation of the transmission fluid.
Somehow, I feel less than confident about this. Auto companies are usually the ones saying that additives are not effective and not recommended. Seems to me that Ford should replace the fluid, but guess I will have to take what I can get.
