Type F hasn't been used since the late 70's/early 80's.
I was talking about the power steering fluid spec, not transmission. My 87 owners manual calls for type F in the power steering pump, and I'm pretty sure the 94 I took an engine from called for the same thing.
It doesn't make any difference if the thing you are lubing doesn't have clutches like the trans does.
This makes sense too. I found another thread where someone said something similar:

The motorcraft Mercon V page linked to by FORDF250HDXLT also says not to use in applications that specified Type F.
