AT fluid suggestions?
Hey all,
New to the 6.4, and even newer to automatics. I just bought an 08 with the Torqueshift 5 spd, and am going to change fluid/filter, as it just passed the 100K mark. No reason other than that to do it, along with the nasty things I have heard about the old 7.3 autos. To me, pretty cheap insurance.
Would anyone recommend synthetics over plain old Ford ATF? My rig is mostly a paver, towing anything from a 7K boat to a 3K contractor trailer, to occasionally a 8-9K gooseneck or pintle, but is pretty rare.
Looks pretty straightforward, but of course, I like to check with you guys first, especially being new to this particular engine.
Thanks!

I would use either the Motorcraft Mercon SP , which is what your tranny calls for or the newer Mercon LV , which I think has been backed speced to use in the SP applications. Both are really good fluids so I would not worry about trying to find something better.

Both the Mercon SP & LV can be used. Both are very good. Your owner's manual should spec the SP. The LV is a lot more $$ from what my dealer told me, so why bother w/ the LV. My 2 cents......
