A904 questions

So I’m rebuilding my 904 due to it not shifting correctly. I beat the linkage to death trying to get it to shift so it wasn’t that.
Anyway I’m new to this trans and it’s missing stuff? First the accumulator spring was gone? The valve was just wedged in there cockeyed so it wasn’t moving?
Also the valve body is missing check balls? I think there is one missing in the center and is there suppose to be a high pressure relief spring and check ball in the corner?
it’s a 1968 non lock up with no part throttle kick down.
Thanks.
I also have the Carl Monroe torqueflight book I’m using as a guide.
