AA, think you may be misreading it
it is from my 2013 manual and it says it will
downshift thru gears 1 thru 5 (i.e. it's hard to downshift to the top (6th) gear!)
Also - I just posted about the gearing, etc...
I am familiar with the ford's, having had five ford deezles since 2002
and learning from the ford engineers that frequent FTE...
one thing it also does, is lock up the torque convertor so that WHEN that big 6.7 liter air pump has the variable vane turbo closed down,
it supplies tremendous back pressure trying to turn over pistons that are air locked and can't get thru to the exhaust...
really not sure why you don't feel the stopping power of it...
I have had passengers say it almost bruised certain soft tissue when they slammed into the seat belt going down the gears so fast...
turn on your gear selector display,
turn on tow/haul and next time you have a clear road and not towing, just hit the brakes hard and watch the gear selector fly thru the gears and assist your brakes...
And there's always the manual gear section where you basically have a manu-auto tranny to shift the gears with the little + and - buttons
can act like a sports car with a paddle shifter !
sorry to sound like a ford commercial
but it does work and I give credit where credit is due !
