I'm only going roughly 60 miles, the road is winding, and curvy, and a few hills, I'm just used to my 2005 explorer that had a o/d button u push for on and off, have never experienced the autostick feature before, so when u talk about the autostick feature where it has the +/- it's very confusing, cuz when I 1st used it it automatically put me in 6th gear, so if I'm going up and down hills, is that when I use the +/- and what gears should I be in on the up and down hills? Just dont what to ruin my transmission
