fine. 5th gear = overdrive on an auto. you should stick with the american transmissions though because i hear they have the best tasting rations aroundRac3rX said:Your just confirming what Im saying
"Overdrive
By definition, an overdrive has a faster output speed than input speed."
That simply explains how this is acheved through a auto tanny.
The Means to an end result being to maintain the driving speed with less output power. The 5th gear ration on a manual also acheves this by another means.
Overdrive IS A high gear used at high speeds to maintain the driving speed with less output power.
