rebuild time...
I remember the very first trans I did, kinda worked when I was done and worked well by the 4th time I redid it. Back in them days there wasnt cool things like internet and the 'books' were indeed non forthcoming. One thing worth mentioning is to keep all the parts the same side up as you disassemble on plenty of newspaper, take lots of pictures and make notes on the wierd things, the angles of the sealing rings etc. All in all it is just a big gray mysterybox that needs someone to tear out it's insides and replace them with something newer...kinda like X old ladies or something.
Good luck on your quest!!!
