Transmission
I have a 03 7.3 Auto / what transmission do I have?I have been given 2 different types of fluid from Ford Dealers and they say both will work but I have been reading some of the Post I am worried that I might need to drain it and replace with the correct fluid.Last time they gave me the Mercon V Mercon and I called them back and they say they put that in ALL Autos!!They get it bulk and that is all they have.I have been using the Mercon untill last time.I called 2 dealers and got the same answer.I plan on this Truck lasting a long time. Thanks
