I know h&s put there truck on a dyno with like 1700 ft pounds of tq and it held

But spe will build you one to your specs

I guess there lies the problem, this trans will hold for everyone with a chip/exhaust/intake so why spend the R&D cash. need someone with 100g to build a monster motor so the rest of us can enjoy the parts that come with that.

 

The H&S shop truck put down nearly 900 and almost 1700lbft of torque before they broke the trans..I really don't see the need in upgrading unless you have something crazy done under the hood

 

I'm going to daily this truck....want a little bit of reliability not just "hope she don't blow!

 

If your going to DD it then I believe the stocker will hold. The trans on the 1700 ft/lb H&S truck didn't even break it just slipped once they got back down around 800 HP it locked back up and continued pulling. Or at least that is what I understand.

I think you'd be good with a stocker. Don't know too many dd that are over 1700 fptq

 

my plans are fairly aggressive;

replace factory turbo (not set on the replacement)
Industrial Injection CT kit
100HP Injectors
Fluidamper
Snow performance stage 3 kit
Elite Diesel Valve springs
Elite Diesel Head Studs
Elite Diesel pushrods
Elite Diesel Stage 1 camshaft
Carillo Rods

not in this order, as i will probably purchase some of the smaller items and have to save for the big stuff like rods, injectors and turbo goodies. i have a sinking feeling that the trans will not enjoy the daily abuse it will receive from a setup like this.

who knows maybe by the time i collect all the parts someone will have a trans.

 

Unless you start with giggle gas I still believe that the stocker will be fine. There was a 250 shot of giggle gas on the H&S truck. If H&S would not have done the torture test I would say that you need to upgrade it, but they proved a lot of things when they did that.

ill be the daily driver guinea pig i guess!

 

People keep talking about the H&S truck like that's the be-all, end-all. Sorry to say it, but i bet that transmission would let loose waaaaaay before those power levels were reached. Nice smooth application of power on a dyno where the driveline is stationary and nothing is being jolted, shaken, or having the geometry change is a far cry from what the actual application of that power is on the road. Also, ONE TRUCK has been tested for absolute failure. I would hardly trust those numbers. If there were ten trucks that they performed the same test on, and they all failed under similar conditions and at the same values, than the numbers would probably be trustworthy. But for now, i wouldn't be pegging anything to their results.

 

I agree that it is not definite proof of what all of the 6.7 can take, I also agree that any trans can let go for any reason at any time.

But staying in line with what you said - can the, known stout, 5R100 take that punishment even in a perfect scenario? No I don't believe so, not even for one run and we know how stout it is.

All I am trying to say is that it looks like ford has one bada$$ trans with this one and that it can handle a lot more than its predecessor. Even if it is in a perfect scenario.

It can hold a whole lot more than a stock Allison

And a ton more than a stock Dodge 68whatever. Apple to apples for a stock tranny the Ford blows them away

I still don't trust it to daily, not with serious motor mods. id like the confidence to know that i can roast some chipped cummins at a stop light and not worry about the trans.

 

you'll be fine with the mods you listed.. like said before its a stout transmission.. for a daily i can't see you running past 800HP

 

What serious motor mods are we talking about?

 

Did you not read the thread?

 

I must have totally missed that the first time I just saw it today. Thanks

 

all i can say is coming from a heavy modded lbz with a allison in it the torqueshift blows it out of the water . my allison would hard shift ,slow shift , slip etc im much happier with this trans
