I was reading an article at caranddriver.com about the H-D edition of the new International LoneStar and it said that the truck has an 18 speed. Having only driven for UPS, I was curious of how one shifts this transmission. I found a couple of videos on youtube that somewhat explained the process. I still have one question: if you shift using the clutch, would you use the clutch for splitting each gear? I do know it is not neccessary to use the clutch at all when shifting (except to intially take off from a full stop), but I am asking this from the perspective of one who uses the clutch at all times to shift. P.S. I do not wish to get into a debate about the merits of using the clutch vs. not . I fall in with the clutch camp and I cannot be convinced otherwise . P.S.S. The H-D LoneStar is one cool looking truck!
