Our TV is a 2007 Dodge Dakota Quad Cab, with auto tranny and FWD.
In 2008 we drove to So Cal to buy our 17'
casita, and towed it back to WA.
The Dakota "tow" button works differently from the above posts, in that, when the "tow" button is set, the tranny will not go into overdrive, period.
The best part of this setup is that when going down a mountain, the tranny will also not go up into OD, so it acts as a compression brake, thereby minimizing the need for using the
brakes.
Even on level ground it will not upshift into OD if the tow butten is set.
Even going up over the Syskiyou Summit in So. OR. it rarely dropped down into a lower gear, and never dropped lower than 1 gear lower. Coming down the summit, we rarely needed to use the brake pedal.
We have a lot of issues with some of Dodge's production decisions, but we love the way the Dodge "tow/haul" button works.
