Thumbs up Who tows in overdrive

Adding to the previous post on tow vehicles, mileage, and weight, wondering how many of us stay in overdrive and when do you switch it off? We have been using the same tow vehicle for 8 years mostly in od except for hills with no problem, change the trans oil every 20-25k with no strange particles in the pan, trans hunts a little on grades but I like the lower rpms in od. My excursion in od runs about 2100 rpms which seems to be the engines sweet spot. Has anyone cooked their trans running in OD?

The newer Dodges have tow/haul and o/d off. I always use tow/haul and if I am towing in a real hilly area go to O/D off as it cuts down on shifting. Mind you Hemi's love to rev so having it running it in the 3500 range is no biggy.

Speed Control On - Tow Haul On

With the Allison Tow/Haul mode it works best with speed control on (except on slippery roads - NEVER do this with speed control).

Up shifts and downshifts occur at the correct points to maintain speed. Due to the shift point at cruise, occasionally the final shift to 6th gear does not occur when I get to cruise speed (usually when its a 55 MPH highway) when we are on level road. When that happens I just click off the Tow/Haul, let it up-shift, and put it back on again. That seems to make the Allison happy and my tach shows a 300 RPM drop. Approaching a grade, the transmission will shift as necessary to maintain speed.

I used tow/haul mode for my trip home to. it holds rpm's higher to keep the power and down shifts to help braking.
