Engine brake question
Traded in my 2004 duramax for a 2017 Powerstroke which comes with a engine brake. I have never had an engine brake before and was wondering what you do or how to use it when coming down a hill pulling...

There are 2 different modes of the engine brake on the 2017. When you press the engine brake button 1 time, that is manual mode. It will start braking when you release the gas pedal. As you brake again the truck will downshift and will brake more. When you press the button the 2nd time, this is auto mode. When you release the gas pedal it will remember the speed you are at and hold it at that speed. Press the button a 3rd time and it turns it off.
