I am wondering if the new 3v V10 w/torqueshift can pull 5-7000 lbs trailer in overdrive through some mild hills in Montana? Can it pull in OD with a 20,000+ lbs cattle trailer? My old 2000 V10 with 3.73's needed Drive for cattle and shifted in and out of OD quite a bit in Montana hills with sleds. I am assuming the 3 valve with 4.30's is a great improvement. I'm currently running an 03 6.0 powerstroke, but am always curious about going gas again.

 

first off the torqe shift has a tow and haul mode botton not any od. pop that baby in t/h and watch it work. up hill and engine braking down hill. i feel it should but at 20k you really need a diesel.
just a thread or 2 up is from big cheese.he just did a wopper of a pull. with his. dropped in mpgs big time with a 13 foot high sail. but he he has great words for the v10.
for me max i have yanked yet is only 7k so i'm really no major help. you have a tough ? for hauling cattle and that much weight, but my personal thinking is if you can't swing the extra coin for a diesel , the v10 is your next best motor

 

My 6.0 has the tqshift. I meant, will it pull in top gear? I only haul the cattle 90 miles. So not a big deal, but I haul the sleds about 1500 miles round trip. I'm running the diesel right now, but just always keep my options open. I've been curious about the V10 with the tqshift now.

 

the v10 is with out doubt the best gas motor ford has put into the super duty for just about every use.! in my mind for your use and driving needs i think that your driving what you need right now.
but if gas and diesel fuel prices keep going the way they are, and without any doubt in my mind ford is going to be selling more v10's then 6.0's . as work wise they both can do it. just one makes a lot less noise.
good luck man

 

The 3.73's is what killed you - believe me, I have them and if my boss wasn't hot-to-trot to lease this truck (found it on the lot), I would have ordered 4.30's.

The beauty of the 05-06 3v v10 is not only the new found HP and torque but they mated the 5R110w Torqshift in her as well limited rear gears to 4.10 or 4.30 only

the OD issues we used to have with 4R100 and 3.73s are long gone.

20,000lb trailer will sure make the 3v V10 earn her keep but set up with the 6sp ZF or the 5sp Troqshift and a set of 4.30s she won't sweat very much. 90 miles will not phase her at all even at upper elevations and many switch backs. My truck with a max GCVW of 22,800lbs manages the tallest stuff youcan find in Colorado with no problem. If I upped the weight to what you are talking I am sure I would spend more time in 3rd at 3600rpm but she will do that all day long. (sucks a lotta fuel though grin)

 

Fred you've made references to how much better the 5-speed is before. Just how much better can the 5R110 be over the 4R100 when
towing at speed if 2nd, 3rd & OD in the 4R100 are the same ratios as 3rd, 4th & OD in the 5R110? The 5R1110 has a deeper first and a bit longer 2nd ut after that they are the same.

Is it the 5R110's abilibty to hold the gears longer (read: Tow/Haul) or is the TC somehow more efficient or... ??

 

Beefier tranny overall. No more weak spots like the TC lockup clutch (or lack thereof) or O/D clutches.

Where's the beef?

 

My cattle towing is actually back here in eastern North Dakota in the flat land. So my big loads are on little hills and flat areas. The old V10 would run in OD with the cattle if there wasn't any wind.

 

The 5R110W and 4R100 differences that make the most dramatic change, I think, are the larger lock up clutch, full time pressurized solonoids, much inproved cooling, filtering method, and the Tow/Haul shift strategy.

If you remember the Tranny wars right here in BSEG heaven, the prevelent complaint against the automatics is that "drivers" would shift earlier or later then the "computer" does with the 4R100/E4ODs that they had experiance with.

My argument was they did not appreciate that Ford significantly changed that complaint with the TorqShift. (and Tow Haul strategy)

Anyway, no it is not really as simple as top gear ratio and OD ratios but a combination of how the auto gets there and how it behaves once there.

And it is pertainent to remember that the extra HP and Torque and the 4.10 or 4.30 only make for a package that NOW can be put in OD and Forgitaboutit (most of the time)

 

WOW! Pulling 20K is a serious job for any truck! I'd kinda think you wouldnt want it to go into overdrive with that load. Maybe I'm thinking wrong, but, in overdrive wouldnt it load on the tranny so much as to make it slip BADLY and burn it up? Also when under a heavy load gas engines like to rev, not bog. Again your looking at WAY more stress on the driveline just to save 1 mpg or so... I dont think its worth doing.

I cant imagin I myself will ever tow without the tow/haul mode on, and I'm only pulling around 10K. Did pull away from one stop light with it off by accident, but noticed the truck wasnt pulling as well as it had before right away and turned it on. I think the truck shifted to early with it off. And what made it catch my attention is it didnt seem to have the same amount of power with the same amount of throttle (line pressure in the tranny I guess, dont know).

 

I run mine right now in tow haul mode when I tow. The 6.0 liter pulls it in top gear. Air Bags are a must have with that weight moving around. Here's the question.....Can I tow in top gear at 80mph with 10k gooseneck in tow? Some of the interstate has rolling hills on I-94 in ND & Montana. I rode in a 2v V10 with 3.73's towing, that shifted in and out on alot of hills in Montana. I don't want to buy a 3v with 4.30's and end up in that same position again.

I know exactly what you mean, my 2001 F250 had the 2v V10 4x4, 3.73:1 stock tires and 4R100

Trany "hunting" was an serious annoyance. I mostly controlled it by punching the stem mounted OD lock out button when I felt that the trans was not going to deal with the slight rises the way I would.

I tow quite a bit with the new truck having 4.30:1n 4x4 and the 5R110w TorqShift.

99% of the time I just put her in "D", punch the stem mounted button to add in the "Tow/Haul" mode and leave it alone. There are a few times when certain traffic and hill / uphill turns that a down shift out of OD may be a little late but usually not enough to have dropped my sped down too much. The power of the 3v V10 is enough to hold the speed.

Any way what I am saying is that all those BAD behaviors of the 99-2004 lower HP and 4R100 with 3.73:1 are gone. This package can have the cruise control set to 65-75...tow Haul activated and you now can concentrate on driving.

The computer controlled trans and THROTTLE being completely electronic also has the benefit of being the smoothest operating Cruise Control ever. I have about 460 mile range in a 38 gal tank of fuel. When I get down to Interstate 10 and up to cruise speed I never touch the throttle again until I climb off the super slab several hours later to get a new load of fuel.

Best combination I have ever towed heavy with

 

Thanks for the input! That was what I was hoping to hear. I figured with 4.30's the RPM should be high enough to put it in th power band @ 75-80mph towing.
