Sunday I will be going down Black mountain. Am I correct that I should: 1. Turn off tow/haul 2. Manually put in 3rd gear 3. Turn on hazard lights 4. Hang on? Thanks
I leave my '11 Super Duty in tow haul mode and I do not switch to than manual mode. Tapping the brakes in the tow haul mode will downshift. I have no problem on 6% and 7% grades. At the top of the grade, I set my speed at the suggested truck speed before I start the descent. If I have to manually downshift, I use the buttons on the shift lever.
The '15 Super Duty trucks have an engine brake that works very well.
