Gives me these speeds.




Would be a reduction of 17,09%.
Or a save of 7%?
There are other aspects to consider before messing with the diff ratio. An automatic can have a wider gear spread, and there is the multiplying effect from the torque converter. Sure a higher diff ratio increases the top speed and decreases revving at cruise, but the throttle response becomes slower and the performance on hilly terrain may be severely affected.
