Thanks for the tips guys. Edited this post with some new info as I mess around with it some more...

This morning is the first chance I had to look at it again. So when I put it in gear, the speedometer at first didn't move. The clutch pedal felt okay, and nothing looks out of the ordinary from a quick look underneath.

As I played around a little more, shifting and listening, it sounds like the clutch is grabbing because I can hear some sounds from the tranny as if things are spinning.

The speedometer will move sometimes, a little anyway and not always, and when I shift I can grind some gears a little bit (very little). Still, the truck doesn't even inch forward or backward at all.

Does this sound like the clutch isn't fully grabbing? Could some shaft in the transmission have broken? I tried all four gears and reverse, and the same thing happens - not much of anything.
