Nope he doesn't. He has the Torqueshift 5sp -5R110W. It was introduced in 2003 behind the 6.0L PSD. The 4R100 was behind the 7.3L PSD.
Tow/Haul will not affect the aggressive behavior of the engine management system to maintain speed while using CC. The tranny will drop gear(s) and rev like heck to maintain the set speed.
You either live with it, turn it off on hills, or put a programmer on it to change the shift program. It does not matter if it's in T/H or not.

I guess I should have clarified... I have a 2011 that has the 6.8L V-10. So I guess this means that I have the "latest and greatest" already.
I get what many of your are saying, about letting it rev high and about using the cruise. I admit.. I drive big trucks and max my RPM's at 1500, so EVERYTHING sounds like it is over-revving. But at the same time... I don't understand why, with the cruise off, it will maintain a given speed up a rise without downshifting, but with the cruise on, as soon as there is any slight upgrade (not talking mountains here...) it instantly downshifts.
The previous owner suggested, and it seems to be the best option currently, that as soon as you see a slight rise, you kick off the cruise, get up the hill, cruise back on. Repeat as necessary. It works, but it does make for fairly tiring driving. (Again, coming from someone who is used to spending a lot of time in the drivers seat. I just don't feel that driving a Motorhome should be that much more tiring than driving an dual axle sleeper with a 53' trailer, but it is...)
Again, thanks for the suggestions.. I did look into the 5 star tuning as someone mentioned (see the third post in this thread), and I did look at the Banks system (looks like that is for the older Fords).
Anyone else, please feel free to chime in.
Thanks!

I was wondering if anyone has any suggestions on remapping the shifting on a Class A with the Triton V10. Just purchased a used coach and it just will NOT stay in high gear for ANY kind of an upgrade with the cruise control on. Any slight rise and it downshifts, kicks the RPM's to about 4000 and screams up the hill.
If the cruise control is NOT on, it doesn't downshift nearly as aggressively.
Additionally, I would like to bring the shift points of each gear down slightly as I am more concerned with fuel mileage than in being able to race up a mountain without losing any speed.
I have heard that it can be done... I just don't know what my options are to doing it.
Thanks!
