You can sometimes find yourself feeling as if the engine is revving too high.

But I could never resist dropping out ot Tow/Haul mode every once in a while, and letting the transmission regain it's composure.
And I'd start the process all over again. |
Gas engines have limited “engine braking” capacity, just like they have limited power-producing capacity.
While making power, “the computers” can control throttle and fuel injection to limit power and or RPM if that was what was needed, but when an engine is not making any power, and is only trying to slow a heavy motorhome down a mountain, what exactly can the computer do? Throttle and gas are essentially already closed so what’s going to limit engine from going faster and faster unless brakes are used?
Just to be clear, I know the correct answer. I’m asking a rhetorical question to help clear this issue.
And to be extra clear, I’m not suggesting riding brakes is the right answer either.
Does this work better for you?
