I dropped my truck of @ the mechanic to get a tranny flush. I told them that i wanted Motorcraft Filter. He then told me they don't change the filters. they just hook it up to a machine that flushes all the fluid and cleans the lines, filter and everything else. he said in the newer vehicles, the filter is big enough were you don't need to change them. I told him that I have never heard of that! I wanted to bring it somewhere else but the guy is giving me some great business and I just started my own business. The truck is a 05 6.0PS Ford. what do you guys think?
