Everyone who has rebuilt or messed with their own trannies has experienced failure at least once.
Old Torqueflites don't hesitate to tell you you messed up.
Fords love to not shift due to valve body maladies like dust, dirt, newspaper, and other rather finicky governors.
Even simple turbo 350's (anybody remember 375's and what to do to make them) and 400's come back to haunt you. Do the cheap re-drill the valve body plate, remove accumulator spring shift kit with the "stretch the oil pump pressure spring" rebuild and see how it saves money. It will allow it to shift real good until the convertor balloons because the pressure regulator valve stuck/cocked and blows up the guts of the case. BTDT
Do I still want to upgrade my own transmission? I'm still on the fence. Maybe I'll call Greg for advice.

I can see both Greg's, Josh's and bluthndr's side of the discussion and I assume if you go through your transmission and discover a 'new' failure mode, you'll probably call greg. He'll let you know why that happened but it will cost you the time and dough to correct the issue. The school of hard knocks teaches you the right question to ask, and that's the key that opens one of the many doors in situations like this. At the same time you will need to respect Greg's knowledge and not blab it all over the net. Any good businessman would expect that.
Sorry for being long winded.
