Overdrive or NO Overdrive

I've heard a lot of different opinions on whether to tow with the overdrive on or off. With so many different types of transmissions out there it might be possible to tow in overdrive. I have a 4 speed auto with overdrive and I find myself turning off the overdrive and just traveling slower, around 65mph.

How do your guys tow? Are the new transmissions today stronger and capable of towing in overdrive?

Back when I had a 3+OD in my 2000 F350, I would take it out of OD in the mountains, but otherwise I used it on the highway. I had 4.10 gears so it was just hard not to use OD at 65.

I will say, it was the transmission that let go first in that truck, but I was beyond it's actual tow rating.

I think all of the big three new ones are a 6 sp tow haul type transmission that just does it's own thing. I don't really have an overdrive that I can pick or choose anymore.

I have the 3.73 gears, wishing they were the 4.10's. On the flat and not bucking a head wind I can us OD but most of the time the OD is off. Sure bumps the RPM's up though.

I think the key is to take it out of OD if it starts shifting in and out of OD continuously. As I understand it is the shifting that creates the heat and wear.

Is overdrive the same as pressing the towing button on my government built GMC?

On our F450 the tow mode only changes the shift points for up shifting and down shifting still runs through all gears no OD. As I understand it that is how the newer transmissions work. My previous 2005 F350 you put it D when towing and it only used the lower gears use to drive me crazy to hear the engine reved higher all the time. But then I like to be 68-72MPH on the interstate.

I have the 6 spd with 3.73 on my 2011 RAM. I will town in OD up to the point where the hills start causing the transmission to be shifting up and down. Then I will shift down into 5th gear and leave it there until the road levels out again. I actually find no difference in fuel consumption while driving in 5th gear.

I run in 6th on the level and when starting to climb in the mountains I drop to 5th. Seems to help keep rpm stabler. I use tow haul when loaded. With 373 I run around 1750 rpm at 68mph

I think the new transmissions can handle the load. As Brad said, if the transmission wants to shift too much, you should lock over drive out. I used to set my cruise and let the the transmission and diesel work together unless I was descending a long steep grade. In my F350 I found more of an issue at slow speeds while towing and having third and second gear shifting back and fourth too much
