A plate warns to only engage the unit in third and fourth gears.The most fundamental meaning is that of an overall <a href="http://en.wikipedia.org/wiki/Gear_ratio" target="_blank">gear ratio</a> between engine and wheels, such that the car is now over-geared and can no longer reach its potential top speed, i.e. the car could  travel faster if it were in a lower gear, with the engine turning more  quickly.<a href="http://en.wikipedia.org/wiki/Overdrive_%28mechanics%29#cite_note-Setright.2C_Anatomy_of_the_Motor_Car.2C_Overdrive-0" target="_blank">[1]</a>  The purpose of such a gear may not be immediately obvious. The power  produced by an engine increases with the engine's RPM to a maximum, then  falls away. The <a href="http://en.wikipedia.org/wiki/Power_band" target="_blank">point of maximum power</a> is somewhat slower than the absolute maximum RPM to which the engine is limited, the "<a href="http://en.wikipedia.org/wiki/Redline" target="_blank">redline</a>"<a href="http://en.wikipedia.org/wiki/Overdrive_%28mechanics%29" target="_blank">http://en.wikipedia.org/wiki/Overdrive_(mechanics)</a>ඔය තියෙන්නෙ බොස් සින් එක, ඔටෝ ගියර් පෙට්ටියෙ එන්නෙ ගියර් 4යි, OD කියන්නෙ  separate unit එකක්</blockquote>
