All of this is why I still prefer manuals...I'm in control and don't have to
second guess or stand on my head...tapping my belly button to kinda sorta get
the 'automatic' to do what *I* want it to do...
But since the automatic herd out numbers those who prefer manuals...the OEMs no
longer offer manual trannies on the vehicle I want to buy (order new or used)
'Tow/Haul' has only one definition in automotive dictionaries. Why make it so
complicated? If MPG is so high on your list of 'have to have', then don't use
that button. As it will or might get higher MPG, but the increased stresses on
the drive train (engine all the way to the tires) will wear it out sooner. Not
have it fail instantly, but sooner than if you did use that button.
So decide to save a few bucks on fuel and risk the system and/or
component which has the two most expensive parts in any TV...the
engine and automatic (tens of thousands of bucks)
Folks who trade/sell in a few years will 'most likely' dodge that
failure and pass that to the next owner...
