They run around $700 last time I looked.
My amateur analysis is that what a valve body does is pump the transmission fluid to control the clutches in the ATX. The improved valve body will pump the fluid at a higher pressure and give you firmer shifts. This will compensate somewhat for the slippage that can come from increasing your motor's torque.
You can get a similar effect by adjusting this through your ECU as with a chip flasher but in my experience it only lasts a short time until the ECU adjusts to your driving habits.
