Check this Cruise Control Downshifting Thread.
I've driven Class C's with the three-speed C6, four-speed 4R100, and five-speed 5R110 TorqShift. The E4OD you have is pretty much same as 4R100, but I haven't driven that specific version.
My guess is the thread linked above pretty much explains what goes on with a Ford automatic and cruise control. Let me try four scenarios:
1. You want to run Cruise - You experience LOTS of downshifting. In return for the noise you get a very steady road speed.
2. You want to run Cruise but reduce downshifting - Anticipate grades by increasing speed with the accelerator. If you increase speed enough, it'll work. If you don't, the transmission will downshift according to cruise control rules.
3. You want to keep speed as steady as Cruise but you're willing to use your foot on the accelerator - A little less downshifting, and you get pretty close to the speed control the cruise affords.
4. You're willing to sacrifice a tight speed range to avoid downshifts and will use your foot to do it. Anticipate a grade by speeding up 5MPH or so, accept a loss of 5MPH or so, and you'll have much less downshifting. But your speed will be 5 or more above, and 5 or more below, your desired speed.
I just drove ours 600 miles. I tried them all outbound and used 4. all the way home. 4. was much less stressful. Too bad Ford doesn't allow some form of adjustment, but Cruise is useless on any terrain hillier than Texas.
I have tried #5 and it stops some of the shifting
#5- You want to run Cruise - Push in the TOW button. You experience no downshifting even on overpasses. You get a very steady road speed. But it does not seem to do anything about increasing MPG.
