Hilly terrain, absolutely.

Flat ground maybe not unless I might need to stop quickly.

I pull an 9k travel trailer and use it pretty much always.

try the TH and if you like it for all driving conditions use it ( does not hurt anything ) otherwise just use it where it really shines , hills and downhill

 

Guess I will do that. I hauled it 40 miles into town today with the tow/haul on and did just fine. Guess I will haul it home with it off and see what it does. Not much with hill problems in North Texas, just idiots who have no clue what it takes to stop almost 30k lbs.......

 

I pull a 28k trailer with my 6.0. I turn off tow/haul when I want it to shift into overdrive. It usually won’t shift into 6th anyway, unless on flat ground and about 70mph. But I have 3.73 gears. With 4.30, you will be in 6th if you want to be. I always turn tow/haul back on when slowing/stopping, or on winding roads or downhills. Use it when you want it. It won’t hurt the trans

I thought these trucks used a 5 speed automatic?

 

From Mark K 5r110 engineer

Normally the 5R110 shifts 1-2-3-5-6. When the trans is colder than 0F is shifts 1-2-3-4-6.

If the truck is at a speed that is just above the maximum speed to downshift to 3, if you were to floor the go pedal it will shift to 4 instead of 5. This gives a bit more acceleration than if it went to 5. From 4 it can only to to 6 or to any lower gear. It can never shift 4-5.

The overdrive unit is in front and has a 1:1 ratio and a 0.71:1 ratio.
The three speed behind the overdrive unit has 3.11:1, 1.54:1, and 1:1.

First 1:1 times 3.11:1 = 3.11:1
Second 0.71:1 times 3.11:1 2.2:1
Third 1:1 times 1.54:1 = 1.54:1
Fourth 071:1 times 1.54:1 = 1.096:1
Fifth 1:1 times 1:1 = 1:1
Sixth 0.71:1 times 1:1 = 0.71:1

 

That would be the guy to listen to for sure!

Zmann is correct(provided correct info).
Until the trans warms up(about 2 shift cycles, haha) it uses 4th. After that it goes 3-5 and skips fourth. Odd, but it is what it is.

Only when < 0 F though, right?

it really seems like a silly strategy who really sees 0 often and how much could this ratio option help 4

would have been nice to have a true 6 speed

 

Technically it has 6 forward gears

It does only use 5 of the 6 gears for shifts, ...I think he is counting the torque converter lock as the last speed -- which is kind of right -- not a gear, but it is a speed

we asked that very question to Mark K he said it did not matter when you used T/H
if it was able to damage the tranny the software would limit it's use

 

I had an 06 F350 with the 6.0 and pulled a 14K 5W with it. I found in hills it wanted to seek gears at times and I would then us tow haul. I talked with a local mechanic who's advice was always use tow haul when towing, it changes the shift pattern and it will hold gears longer. He said the engine will never over speed as the ECM will not let the engine self destruct, worked for me until I sold it. X4 SCT set to tow and EGR delete only other wise all stock.

 

I have an 09 and a 8700 5th wheel and don’t really use tow haul unless in hilly area, I did notice that with the camper plugged in, it’s like it automatically take OD off but have no down shift.

 

I am a firm believer in TH, it definitely helps me slow the truck. My truck is a 06 F350 DRW, I use it transport hay and my D4 dozer. I definitely overload this truck on a regular basis but, Texas Farm Tags help me get around the weight issues. She does fine with about 18k to 21k without TH on traveling average speed of 75 Columbus back to Houston. I prefer to use TH when I can remember to turn it on, the truck definitely shifts better and performs better over all. This is definitely a hot button topic in my circle, the 7.3 guys say I am supposed to turn it on while trying to get up to speed then turn it off while cruising at highway speeds. All I know is that my truck accelerates, shifts and stops better using TH.

 

Get one of these. Works way better than tow haul and then if you do use tow haul, it really works great! Plus you can choose your gear. BD TapShifter with Integrated Exhaust Brake 03-07 6.0L Ford Powerstroke

How do I use my SCT monitor and this device at the same time?

 

Here's my SCT showing 6th gear..

Towing my 9k 38' TT.

This device doesn't go through your OBD, if that is your concern. I don't know how an SCT monitor works. This device taps into some wiring under the hood.. I had their previous version of an exhaust brake that uses a butterfly valve where the cat was, powered by an under the hood compressor. This new one is way better, utilizing the variable vane geometry to supply the back pressure.

 

this is directly from the Q&A on their site.

 

My question is:

If one has specific tow tunes and installs the BD shifter, does this in any way conflict with tuning and trans functions?

It would be nice to have the option of locking in on a specific gear without having to play with the accelerator pedal and play that game all trip while towing.

 

I agree that it would be nice to lock it in one gear. I wish I could hold it in 6th with the convertor locked and letter eat.

Although that does come with increased drive pressure. For the non-studded crowd, it is healthier for your truck all around to be able to increase the rpm to match the load rather than hold it down and crank the boost.

 

Well, I was right. Mine is a 5 speed automatic! That is why they are called a torque shift 5 speed automatic!
Any way, drove the truck with the trailer loaded using tow haul and not using it. I will be using the tow /haul mode in town for sure. Highway driving the tow haul will be off unless we are in traffic or at low speeds!

It's a 5 speed transmission with OD. While technically not a gear, I think they count OD as the 6th gear. It shifts 1,2,3,5,OD or if below 0F, 1,2,3,4,OD.

So, you have the same trans as the rest of us...you're still not special 😁
