When do you use the Tow/Haul mode?

A jake brake is a brand name device internal to the engine made by Jacobs, generically known as compression release braking. By releasing the compressed air in the cylinder very near the top of the compression stroke, the air does not re expand to return energy to the piston as it moves back down. The vehicle motion pulls the piston down and sucks air into the cylinder and provides the energy to compress the air in the cylinder, thus slowing the vehicle without using the service brakes.

I'm pretty sure this is right:
My 6.0 SD was an early '04 (actually 11/03 build date) and it had tow/haul mode.
Like somebody else said earlier, I too only used it when I was towing something approaching 10k or heavier. For lighter loads in the 4-6k range I found it to be more annoying than helpful. To each his own.

You are exactly right.
Some trucks are very loud.
You've heard it plenty of times,next time you see a truck slowing down,or descending a steep grade,pay attention,you'll get the noise.

I am thinking 05 as before that it was just over drive lockout. The best thing about the tow haul is the braking and downshifting. It is similar to a engine slash jake brake or a exhaust brake on heavy trucks. These devices are also very popular with the SD diesel crowd. In 05 with the new t shift also came the tow haul mode. I wish one of these trany gurus would tell me how to shift the trany from fifth to fourth as if u move the lever it goes all the way to third. Five speed gear box but only four gear selection positions. Ford is way behind GM in this respect. The 5 speed torqueshift is a out dated dinosaur imho.

Because of its electronic controls we have developed tunes to either stay in 4th and or stay in 4th and shift into 5th at a certain mph. Ex. Mmaxed in V10 section is running a tune for towing that stays in 4th and shifts into 5th at a certain mph..

I've been meaning to contact you on the Livewire that I purchased back in November. Is there any documentation of the meaning & significance of the various settings of the Livewire? Also, will my Livewire provide the feature mentioned above? I've uploaded the 93-octane "performance" tune but did not change any of the settings. Finally, I get an "error" message when I try to review any stored codes. I'll send an email so you can respond that way if you prefer.
Thanks!

The“TorqShift” (5R110W) is a 5 speed,rear wheel drive unit that actually has six forward speeds available,depending on hot or cold mode operation. The gear ratio for 1st gear was lowered from 2.71 to 3.09 (compared to a 4R100). For 2nd gear the overdrive clutch is applied to provide a ratio of 2.20. 3rd gear provides a ratio of 1.54, which is the same ratio as the previous second gear. All sound familiar? When in cold mode operation, below _15°C(5°F), determined by the TFT sensor, the overdrive clutch is engaged in 3rd gear to provide a ratio of 1.09 for 4th gear, and the transmission will shift directly into 6th gear (overdrive), which is a ratio of 0.71. In cold mode the transmission shifts 1st gear, 2nd gear, 3rd gear, 4th gear, 6th gear.When in hot mode the transmission will shift 1st gear, 2nd gear,3rd gear, 5th gear (ratio 1.00), 6th gear. Either way it is still a five speed unit with six forward gear ratios available, depending on cold mode or hot mode of operation.
I always thought that there was no 4th gear manual selection because the transmission actually uses 4th or 5th, depending on whether or not it is in hot or cold mode.

That is correct.
Nope. It was cost, plain and simple.

The name sounds familiar, but I can't place him.

Isn't that usually the case when it comes to such things.... glove box lamps, fender liners....

Thanks Mark. What about towing something heavy without being in tow/haul for the sake of less down shifting at cruising speeds. How much heat does the trans generate in overdrive towing heavy, and should I keep it in tow/haul when towing for the sake of the tranny's life span? Or is the difference minimal?
