Where are the shift points on this truck located? Talking about speed wise. The reason I ask is because if my speedometer sits at 60 and im towing, every little bitty incline gets me to down shift. If im sitting at 57 or so, it doesnt down shift as often. Just so you know, im off roughly 9.7655% due to bigger tires, so I always figure it about 10% which means I would roughly be at 65-66 when it downshifts a lot. Just wondering if this is normal, or im sitting right at a shift point, ect. My Dodge doesnt do this on the same hills and this is why im curious.
