Has anyone been able to find a breakdown of the speed brackets that these gears are divided up into? With 10 gears there's bound to be constant shifting for regular city driving. I'm guessing that 1st to 3rd is 0-30km/h and 3rd to 6th is around 30-65km/h. From what I've been reading its highly unlikely you'll ever get out of 8th gear should you follow the typical highway speed limit of 110km/h. That would suggest you'd need to be going approximately +120km/h to even make use of the final gears. Not sure why they even looked at 12 and 13, as it doesn't look like the truck would spend much time in them.
