I too find it hard to believe that the Ford recommended fluid change of the trans fluid is at 150,000 miles !!! I will be changing my trans fluid at 50,000 to reduce the accumulation of debris on the filter. 150,000 miles is a lot of accumulated debris on an apparent "unserviceable" filter. It can be changed, but who wants to tear a tranny apart to change a filter. Besides the filter will last at least until the extended warranty runs out :rolleyes: :rolleyes: :rolleyes:
