    Just wondering how often you guys change the fluid in your transmissions? I have an 04 f350 dump and and 06 f250 long bed pick up, both are plowed and tow trailers?

    Every fall regardless of mileage- fluid and filters are cheap.

    Will the Mercon SP work in the 04 as well as the 06? Any one know how much they take? I bought the trucks used and they didn't come with the manuel.
