David,
You may want to recheck your info. The engine will not over rev. On the interstate at 65 mph if the jake is activated mine downshifts to 5th gear until the coach slows enough to shift to 4th gear without over revving. It does not go straight to 4th gear when the jake is activated unless rpm wise it is safe to do so. I have even heard of people programming the coach to shift to 2nd gear when the jake is activated. Under this setting the trans would shift to the lowest gear possible without over revving the engine until it was down to 2nd gear. The Newell tech said he reprograms them all the time for people who live or drive in hilly areas. My Country Coach was also programmed to 4th gear. It performed without a problem for over 168,000 miles .
