I hope I don't offend you boy's as I refuse to read the last 6 post's or so because I have had much drink and it makes me dizzy. But being the highly coveted 7.3 IDI turbo E4od/4.10 the cruising speed (well mine anyhow) @65MPH is about 2250 RPM's The sweet spot as we say For the Indirect injected diesel. (not gasser) So pulling the load in question the only time it will drop from OD is on a substantial grade and the throttle position determines the downshift so if it would down shift it will be at approx 3/4 throttle and needs the lower gear to pull the hill. I completly agree that heat is the #1 enemy of any trans and in this weather when the fan clutch kick's in at 198*engine temp it will be plenty of cooling through the factory cooler. That being said go buy the biggest tranny cooler you can find at put it to good use. I sure hope I don't read this in the morning and think.....WTF was I typing

99 7.3 Powerstroke, 3.73s. Tow everything from a car hauler to 10,000-pound travel trailer in overdrive. Rule of thumb, if you are under 55 mph lock it out or if you are climbing a hill lock it out. Another rule of thumb, stay over 75 mph and don’t worry about shifting out of overdrive. I think the key is don’t let the trans “hunt” or shift back and forth between 3rd and 4th.

I hear ya. There are certain people here that just dont want anyone to post a second opinion. They are SMART.

For the record, I am not the one starting the crap! (ie. I didnt make the first slam).

so in summation:

towing in OD is OK, just be careful. keep an eye on the temp, and be smart with your foot. nuf said?

besides OD is just another gear right?

Grassman I would say in most cases that yes what you said is right but there ARE exceptions to that rule.

I have an 02 SD Powerstroke 7.3, 3.73 gears and it has some mod's done to it. I was pulling 10,000+ in OD and I thought it pulled great. well it took about 400 miles but OD went out. At that point I had the trans re-built with all the upgrades to make it bullet proof. No problem since, it's a great truck for pulling. If I was that heavy again I would run with overdrive off. I do have a trans temp gage and when OD went out the trans temp was just fine. With your gear it might be easier on it... Good luck

IMO only use OD after you have reached your hiway cruising speed
