904 problems

I'm have a problem with the cable style 904 and one of my barracudas. I stalled it up and now it acts like it is stuck in low gear. It will not go reverse or neutral. It tries to move forward in reverse but acts like the trans is locked up and in neutral it will go forward. And when I put it in park the engine will not rev up. Cable is fine.

I read other post so I'm guessing maybe the clutches welded themselves together or something? Guessing maybe it's time for another rebuild? I will pull the pan off when I get back home this weekend, just thought maybe I can get some advice and what to look for first.
