I tow with O/D
on and I only turn my O/D off when I get to an incline. In the mountains, I tow in second gear going up and down the mountain. If your pulling a trailer with any significant weight, engine braking in third gear, as refered to in the manual, is almost useless. It says nothing about the life of the transmission. If your looking for a great brake controller, get the Prodigy by Tekonsha. It is the most advanced controller on the market and it has made all other controllers obsolete. No need to hook ugly cables to the brake pedal (like you have to do with the Jordan Ultima 2020), and it makes for a clean installation. Mine sits in that little cubby hole right under the ignition switch. It is easy to read and very reachable. My Prodigy is gray and matches my dash perfectly.
