Jake Braking A 5er Down Long Steep Incline
Just arrived at our vacation destination yesterday. I had my factory “jake”brake set and the cruise control on when I crested the top of the largest hill going into this part of the country. I’ve ...

I tow in tow mode and use cruise control all the time with the exhaust brake engaged. The OP has a 2019 F-350, I have a 2018 F-350, my exhaust brake has no auto, it’s either on or off.
We have a 2011 F350 and the true engine compression brake (not exhaust) is only off or on with setting the Tow Haul Mode.
I agree with Ron, please explain all recent HD pickup use an exhaust brake, which uses some means of restriction of the exhaust gases.
Now PacBrake offered a Load Lash device for the Cummins 6.7, that was more like an engine brake.
It's not a true exhaust brake, but merely uses the transmission and the back pressure of the engine. It works and it's efficient, but Ram owners , I beleive, have true exhaust braking.
The 2011 through 2014 Powerstroke didn’t have an EB switch but did have a turbo that was capable of creating some back pressure. In 2015 the Powestroke turbo was upgraded, an EB switch was added and the EB performed considerably better. The Cummins EB works very similar to the Powerstroke in that it is the turbo that is creating back pressure. However, because Cummins engines use stronger exhaust valve springs the EB can be used to generate higher back pressure without danger of the exhaust valves “floating” and coming into contact with the pistons. For this reason the Cummins can generate the same negative horsepower at 3000 rpm that the Powerstroke can at 4000 rpm.
