I have a stock 2014 reg cab manual 5 speed, my buddy has a stock 2013 reg cab auto. I understand they both have the same diff gears? (4:10s) If so is the final gear different in the two transmissions?
we did a little experiment see below:
His auto at 2000 rpms reads 62-63 on speedo
My manual at 2000 rpms reads 54-55 on speedo
note: they both have the same tires etc..
