there should be no reason to have to change PTU fluid
why are so many of you having to replace this fluid?
Well... There's a lot of picture and stories showing either burned up PTUs or PTUs full of black semi-liquid that is the consistency of near frozen chocolate syrup at 20-30K miles.... Many don't have an extended warranty. Ford has a MTBF of 100K miles which will be past any warranty for most.... At 300 degrees in a non-PP how long can a couple of ounces of gear lube last? ...or in a PP that's driven in a spirited fashion.
I agree with replacing the unit entirely if it fails.... But why not PM it to prolong the life? My dealer won't do it because Ford won't warrant the part if they do...
Here's some pics of the PTU... First 2 are what a lot of folks find, third is where the PTU has been drilled for a drain or guage, last pic is what the first 2 should have looked like...
