Gota love the tow/haul Joe that's one good thing ford install help on towing and brakeing, I use to haul heavy with my silverodo in over drive smoked a few trannys because of it.

 

Well, I did not have any problems with the tranny. I drove over 100 miles with it in overdrive, and nothing overheated.

It not heat od can't handle the add strain of the load

 

Well then, Ford should have made it stronger so it can handle the strain. Since these vehicles are required to get the best mpg possible or Uncle Sam will throw them in the crusher, I am surprised Ford would make an F350 that cannot tow anything heavy in overdrive. There is no way I would have made the trip back with the trans in 3rd gear the entire time. Going to have to limit my area of vehicle pickups I guess.

It's not just ford it's every budy like if I was to tow with my burb it has od and non od drive icons

 

Good Morning FTE, Monday Arg time to get going Did I mis the memo that nobody works on weekends, Over Drive is like a 4/5 gear , It States in the trucks Manual Not to be in OD mountain or while pulling a load ? It boggs the tranny down and eventually start to heat things up Internally wareing down the cencrows sorry for the spelling and Bearings. I would'ent see that 350 having a hard time There built for hauling, The higher pitch sound that your not use to 4th ( D) is the gear But take a look in your Manual or stop by a tranny shop and have a talk with the service Mjr on it to make sure. In my Chevy Im in OD on the freeway most the time unless I hit a grade or I feel like the tranny is lagging for more umph. like to pass .Have a good Day

 

HOw is everyone in NoCA?

The reason for overdrive is to save fuel while not towing. So while towing, you need to turn off OD. The only other way they could have done it is to do away with the OD setting. Then it would cost more in fuel to drive while empty.

 

Overdrive and Tow/Haul are two completely different strategies. Overdrive is like an additional gear (high) and Tow/Haul is a completely different transmission strategy where it down shifts more easily when under load (keeping the rpms up) and also will downshift for trans braking on descents. It keeps the engine and transmission happy while they're being worked. Both will hurt fuel economy but protect your engine and trans. Lugging is very hard on the drive train.

 

Just for the sake of clarity, the above posts do not apply whatsoever to a '99 and up 7.3L PSD powered rig.

But would apply to 03+ with Torqushift correct?

As Tim posted above, the TorqShift with the Tow/Haul mode is a completely different monster.

Way, way too many people who have experience towing with other vehicles that have different transmissions than the 4R100 in the '99+ 7.3L PSD, make the mistake about towing with the OD off. They confuse when the OD should turned off, and when it should remain on.

Well, I towed the XJS to my mechanic today, and to keep everyone happy, I turned off the OD. I talked to him about it, and told him I kept it in OD once I got down from the Grapevine (Saturday), and was on flat ground. He said I should be fine. 2k is not lugging the engine, and as long as it is flat ground, it will not put a strain on the transmission. I seriously doubt I will be going over the Grapevine anytime soon which is a good thing because I finally filled up the truck today, and got the revised mpg numbers. For the trip down to Burbank I got 11.6 mpg towing the empty trailer with no AC. On the way back, towing the Jaguar, and running the AC just enough to keep it cool (not during the Grapevine ordeal) it only managed 7.9 mpg

Finally got to use the winch today. Had a bit of an issue getting the Jag off the trailer again because of the steep angle. Finally did it using John's floor jack to raise the front of the trailer higher than the back, and then winching it down enough so he could get in it and drive it off the remaining 3 or 4 feet off the ramps. Put the 4x4 pieces of wood under the back of the ramps to help with the angle but it was not enough. So out came his 4 ton floor jack.

I keep flip flopping as to which Jag to keep and which one to sell. John says he can make some adapters to move the drivers seat back far enough so I can drive it comfortably. If he does that, then I will keep the XJS, then again, he said he did some research on these cars, and tells me I can sell it for anywhere from 6k to 13k once it is done. The XJ6 can sell for 4k to 6k once I am finished with the little things it needs. That would recoup the purchase price of both Jags, so I am leaning towards keeping the Black Beauty.
