<K<Why on earth would Car manufacturers around the world make these things if
this was not the case? They wouldn't waste their money developing the
things. An Overdrive, *properly* used (key thing here), must save $ at the
pump and result in less Engine wear - even a teensy amount less wear is
still an amount, and over x thousand miles that must add up.>>
And indeed, that is why many American cars have 5 or 6 speed transmissions -
to help the CAFE certification, ie the cororate average gas mileage.
