Hi all, so I towed with my ram 3500 6.7 for the first time. About 8000 lbs, and 7 hours round trip. With tow/haul engaged, in cruise control, as I headed up hills At 60 mph, the trans would shift out of sixth (1200 rpm), then it would rev to 2500 rpm, finally settling down to 1700 rpm, fifth gear. It did this consistently for the whole trip. Why wouldn't it simply shift into fifth? Why the big rev? Anyone else experience this? Thanks in advance.
