Well, it just so happens I HAVE a 700R4. Don't come off as the only
person that knows how to figure out gear ratio calculations. Geezus, I
think sometimes you argue just for the sake of arguing.

So in other words you do not know how it works then right?

Re: ACCURATE SPEEDOMETER?
 

If your pedal is near the metal, your engine is lugging at two grand and
using more gasoline than at a cruising speed of three grand, also fourth is
direct, and doesn't use any gears nor bearing like in overdrive. So it saves
the transmission, too.

Re: ACCURATE SPEEDOMETER?
 

Doesn't your Rubicon automatically correct for tire size? Probably by
this '06 it also measures the distance from the ground.
