im pretty sure overdrive is a run mode for the transmission where the torque converter locks with the flywheel (usually above 40 mph), thus giving you highway cruise mileage like a manual. I've never heard of it being a separate gear... Turning overdrive off allows the flywheel to spin faster than the torque converter, which multiplies torque but wastes gas.
i've been wrong before, but im confident with this assumption --------------------  |
