6.4 Fluids

I am sure this can be answered by someone who uses this site more, but is there a general 6.4 fluid thread anywhere? Oil, ATF, front/rear diff, coolant and transfer case. Didn't know if anyone had a list of recommendations all in the same place vs looking for hours to find each one. I am regular on my oil and fuel filters, but I am almost at 70,000 so I should at least do the tranny and maybe check the diffs. Possibly a coolant flush too.

If this thread doesn't exist I can sit down this weekend and try to find all the different fluids.

Also, how hard is it to do the transmission dipstick? Mine is crusty.

Re: 6.4 Fluids

should all be in the manual

trans - Mercon LV
diff - on a tag on each dif 75-140 rear syn may need LS additive see if t shutters around corners

front is reg gear oil IDK weight off hand

crusty dipstick ??

tranny you either get a heated flush at ford or drop the pan do the filter and refill

then maybe run it and drain and refill again to get the clean to dirty ratio up
