Reply to "25-1 trans gears"

JFB -

On the ZF data, it seems to me that this is a pure calculation on the RPM.

For example, when you hit 45 miles an hour in 1st gear (at 5500 RPM), when you shift to second, you have to be doing 3600 RPM (at that gear ratio) to stay at 45 mph.

As the gear ratios get "taller", the RPM drop required between gears is less than needed at the lower gears to achieve the same speed in MPH.

I want to show that I sometimes use my scientific thought process. Now everyone is free to poke holes in my hypothesis!
