I totally agree. That is a blanket statement that is not true in all cases.

In my case I did my homework and modded the PCM to lock the TC sooner than later and then monitored the trans for hunting. Installed trans cooling items and a trans gauge. I've towed several thousand trouble free miles in overdrive...my manual didn't say if it was safe or not. If your manual also doesn't say, or you don't have tow/haul mode, it's a safer bet to tow in 3rd unless you know what you are doing.

Any savings in gasoline towing in OD will clearly be offset by the cost of a transmission rebuild or replacement if you err on the wrong side!

My Dodge diesel manual says to shift out of overdrive when pulling a heavy load, in hilly areas, or into strong crosswinds. It says that when the transmission shifts out of overdrive by itself, you should turn overdrive off to prevent excessive transmission wear or overheating and to provide better engine braking. Daimler Chrysler has monkeyed with this since then, taking away the OD lockout in the next few years and calling it a tow-haul mode with modified shitfting paramenters, and now it's back in the new 06 models. They have both the tow/haul mode AND the OD lockout.

I know that I towed my Excella from Michigan with a 93 Dakota using overdrive everywhere that was flat, and third everywhere it went up. At the October forum rally in Ft. Desoto, I pulled it over some gently rocking hills on OD crossing FL. overlander63 innocently asked me, "So, do you tow this in overdrive?" Then he said "Hmmm."

That's a bit unnerving hearing something like that from a person who knows more about my truck than I do. Although I had no problems at all getting it home, two weeks later I traded the Dakota in for the 03 Ram. And, yes, I will tow in overdrive when it's flat.

I cooked the 518 Overdrive transmission in my Dakota while on vacation towing our Argosy. The torque converter started shuddering when it engaged, then finally failed completely just after arriving back home. $1800 later, I read my owner's manual, and it very specifically stated not ever to tow anything in overdrive. This was a virtual identical twin to Lamar's Dakota. The only real difference was the color.
But again, this is what it said in my owner's manual, and it seems almost every tow vehicle out there makes different recommendations on the subject. The best thing I can suggest is to do what your owner's manual tells you. If for some reason you don't have an owner's manual, you can order one from the manufacturer.

My '92 C1500 with the 700R4 transmission did not recommend towing in OD. The manual for my '04 K1500 with the 4L60E transmission states that OD may be used if the transmission does not shift excessively (gear hunt). The 4L60E also has a Tow/Haul mode. If I remember correctly, the manual indicates that the Tow/Haul mode is designed for use when towing 75% or more of your towing limit.

Ok... Let's see if I can state my question clearly. I own a 1997 Dodge Ram 1500 (1/2 ton). The engine is 5.9L, original rear end was 3.55. The owners manual says do not tow in overdrive. I've owned the truck and my 22' CCD (5,000 lbs GVWR) for two years, and have never towed in overdrive per the manual. Towing mileage has averaged between 11 and 12 mpg. I tow a lot in the Sierras, and on the steepest grades I've wished for a 3.78 rear end. Making a long story short, I recently replaced a the rear end and chose to go with a 4.10. This should give me enough torque to pull my little CCD up a wall, although I haven't towed any long, challenging grades with the new set up yet.
My question is this: Will it be OK to tow in overdrive with the new 4:10 rear end on flat stretches of interstate? I plan to tow hills, mountains, headwinds, and even in-town with OD off, but am curious about OD on interstates with my new, higher RPMs. The manual makes no mention of the 4.10 rear end.
Any input, opinions, etc. would be appreciated.

Much depends on how close you are to the maximum tow rating of your TV and if your transmittion is hunting gears to maintain speed . If it is hunting or getting hot you are in too high a gear. If you are maxed out on tow rating don't use OD. I would be disapointed in an F250 with a V10 that could not tow a 5800# trailer in OD on an interstate.

I tow at about 80%-85% of the GCWR of the original tow vehicle (with the 3.55 rear end).... pretty conservative.

your original set up (3.55) would give you a final drive in OD of approx 2.52 and in third of 3.55.

With the 4.10 rear it will be 2.90 in OD and in third 4.10.

Basicly you have gone up half a gear , I would try OD on the interstate and monitor how the trans behaves,temperature and hunting for gears.

Thanks Tic!
Your numbers are VERY helpful... confirm what I suspected. I haven't towed on the freeway yet, so I"m anxious to see how the new gears perform. I'll try O.D. on the flat stretches, monitor temp and "hunting", and see how things go.

The short answer is YES.
I owned a 1 ton Dodge van with the same powertrain. I would take it out of OD depending on the circumstances, much like you have described. If it starts laboring at all, I would have it out of OD. I never had a problem with this powertrain and the 4:10 rear end.
I sometimes towed for many hours on flat freeways in OD, and would only take it out of OD when encountering grades, or headwind. You will have to pay close attention to the sound of the engine and the rpms, so that it won't slip in and out of lockup, or hunt gears. If you're not good at that, then better leave it out of OD all the time.
