Generally speaking, overdrive is the highest gear in the transmission. Overdrive allows the engine to operate at a lower RPM for a given road speed. This allows the vehicle to achieve better fuel efficiency, and often quieter operation on the highway.
Remember, automatic transmissions came after the manual transmission and if you know how a manual works, youâll get the basic idea of how an automatic transmission works. While a manual transmission requires the driver to manually change gear ratios, an automatic does this on its own through the use of fluid pressure.
