Can someone explain this thing about blue printing? Does that mean they check all the clearances and tolerances to a factory and then draw up some sort of blue print?

When you say beefed up you mean extra clutch discs and different spider gears? I got this nice ATSG book on the A-413 which describes complete tear down and rebuild and also includes schematics of all the lines and passages the fluid flows through.

All this transmission stuff is fairly new to me only thing I have ever taken out was the valve body filter and torque converter
