A904 questions

It had the single post NSS when I got it. I thought maybe they had the wrong switch in there so I swapped it with the 3 pin and then things started coming together in my head that this was an earlier trans. Ha
I’m rebuilding this in my warm basement due to the cold weather here in MN. If the pan comes off a few times I guess I just get a fresh beer and go forward.
thanks everyone for the help!!
