So I have never changed the trans fluid in my 2008. I know what's wrong with me. I'm all over everything else. I dont know why i avoided the trans. i just turned 100K miles. i've owned the truck since it was new and so its life has really not been that hard. anyway i dropped the pan and went to replace the filter and the new motorcraft filter looked completely different. after some looking i discovered my later build 2008 has a pan and filter the same as the 6.0 trucks. I bought my truck in September of 2008 so it was a later build. Im figuring may or june of that year. Anyone heard of this before. I looked and couldnt find anything anywhere.
