New E450 with tow/haul question
My old Winnebago E350 4R100 had overdrive and I would turn it off when climbing a steep grade or go down a long grade for braking. What's the difference with the Tow/Haul on the 5 speed. Same usage?...
Forum Discussion
Tow/haul was introduced with the 5 speed transmission. All the 5 speeds (on the E series) have it, none of the 4 speeds do.
The five speed transmission does indeed have two different 4th gear configurations internally, and it uses one or the other based on conditions. Ford doesn't list separate ratios for them, I assume since the difference is too insignificant to worry about and the alternate one is only used under quite limited circumstances, but there are still two different 4th gears. That doesn't really make it a six speed transmission in any practical sense.
