904 disassembly help needed

yeah, there is friction material on one side of one of the clutches, other than that, they are all bare steel with heat marks. No wonder it didn't run right!

Is that indicative of a faulty valve body possibly? Reason I ask is, I used the same valve body (has a shift kit in it) in a different tranny I put in there and it started shifting funny shortly after that as well. Sorry, I don't remember exactly what it was doing, it has been sitting for a year and a half or so.

Also, sometimes, when I put it into park, if I rev the engine a bit, it would try to creep forward..... very strange.... and both trannys did that.

If it wanted to creep in neutral or park it may have had a valve body issue. The trans may have also been fairly worn and the valve body issue finished it off. If you plan on reusing that valve body you need to take it all apart and clean and inspect everything good cause it's probably full of all kinds of burned friction plate trash. When you get it back together if it still wants to creep I'd diagnose/fix the valve body or replace it with a known good one.

Do you know what brand shift improver kit it had in it?
