Class C downshifting ?
When auto towing with our Ford 450 class C and climbing a slight to moderate hills, the coach downshits and revs really hard and it drives me nuts. Makes me wish the Coach was a manual shift, then all...

I have a smaller 2016 Class C 25ft oal and no slides and no tow. It's on an E350 chassis With the Triton v10. When I hit a long, short up grade, even a moderate/strong headwind it will downshift.Cruise on or not. I was going West across northern Texas on Rt 82 this last summer and the best speed I could get was 60 mph due to a strong headwind. Every time I finally got it going 65 or so and it finally upshifted the wind would slow it down it would downshift. I had the same problem last year heading West on Rt 2 in North Dakota. Very frustrating. I felt I was beating on the drive train so I just backed it down. Lived with it. These class C's aren't very aerodynamic. I had a 2008 F350 with the 5.4L engine that did the same thing. When the warranty runs out on this RV I might mess with the tuning. Well see.
Just thinking about this again.. If I leave it in cruise and it downshift it stays in the lowergear increasing speed well beyond where I had it set. If I knock off the cruise when I hear the engine load increase I can hold off the downshift longer and it will upshot sooner,then engage the cruise again. Hope I explained this ok.
Just use tow haul, and let in stay in the lower gear it wants to be on. Or manually put it in 4th. 5th and 6th are both overdrives on your transmission.
