Yesterday I went down an 8 degree slope and left it in Tow Haul while using the breaks on trailer and truck to slow me down. I was thinking I might have been better off starting in 2nd gear at the top of the hill.
What is the correct strategy for braking on a big descent?
Leave the Tow/Haul turned on while towing, works much better than turning it on when starting a descent.
If the Tow/Haul is on it will do the downshifts FOR YOU AUTOMATICALLY, you can however override the Tow/Haul and downshift early by simply adding some brakes. The computer will however only downshift provided you are not going to fast for the next gear down.
The first time I experienced the Ford Tow/Haul automatically downshifting was our 2005 F250 with 5.4.. Kind of a shock when we started going down the grade and the transmission downshifted without any input from me. Once I got used to that feature it really made driving grades much more pleasant no longer wondering when I should downshift..
