A904 high performance rebuild--advice wanted

It really isn't that hard. I did mine, and I'm having to tweak it here and there but it also helped me understand better how an auto trans works.

It's kind of ridiculous how much people charge. It probably takes guys that know what they're doing just a few hours to build a trans, and for $200-$300 in parts (plus TC) for the good stuff, they're probably making $300 per hour on labor...crazy.
