Unless your running out of gearing in 3rd (D) at the end of the 1/4 turning O/D off does NOTHING!

I still don't understand the point of raising a redline if they can't raise the shift points either in an ATX equipped vehicle, which one can understand if your still making good power above the factory redline why 'shifting' you ATX manually helps you. HOwever, I still believe a VB and a appropriately tuned (i.e. raised shift points) chip would net you better times.
