    It should say on dip stick.
    If not look at owners manual.
    I would say it's Mercon II at least.
    If you plow with the truck make sure it has a good add on tranns cooler. That tranny dies without good cooling! Had a few die under me unlike the C-6 witch goes on forever.

    If I remember correctly Ford says use MerconIII. I know it was the Mercon with the highest number that is not synthetic. I believe Mercon IV is the synthetic.
