Would be? Or COULD be? How do you know? Would be. Because that's what it said on the website was the minimum. It could be as high as 30%.



for all the 5% of duramax consumers who drag race and sled pull their trucks. Great. You don't have to be a racer to enjoy getting in a stock vehicle and going wohoo. Hell that's what sells vehicles. People drive them, people like them, people buy them. If the people that buy them continue to like them, they will sell themselves. Hey come take a ride in my new........ you name it. I have tons of friends that are going to buy a duramax for their next truck, and it has nothing to do with they think it looks cool.



I assume you havent towed heavy with an LBZ or LMM. Either will easily exceed a safe highway speed going up a hill at very heavy loads. We dont need anymore power.

Not the point you would always be at peak torque. This is where the biggest fuel economy gains could be made. 16 mpg pulling 17,000 pounds up mount everest at 75 80 verses 10-12?



The allison has a 4.49 reverse ratio. How much more slow speed precision do you need? A lot with a geared park how many times do you back up to a wagon/trailer and need to pull forward and "repark" for lack of a better term because as soon as you put it in park, you roll forward or backward 3 inches and the park break is a joke.



you're an idiot if you are backing/need to back up a 1 ton pickup truck faster than the current ~20mph max speed in reverse. My dad's 4l80 would back 60mph. I would love to be able to back atleast 40mph. Not to mention how nice it would be to be able to back up at 20 mph without having to run up against the rev limiter. How gay is that? Not to mention while all terrain tires don't clean worth a shit a 20 mph if your trying to back out of a hole.



whens the last time you had to go directly from 20mph in forward to reverse in a truck. And why is a feature like this necessary in any automobile. Plowing snow would be nice, you wouldn't have to come to a complete stop. Not to mention rocking the truck out of a mud hole.




You have a good point, I didnt consider the fact that people could use their duramax's for bailing hay if GM were to spend a billion dollars to implement this new type of trans.

There are a lot of people that run air compressors off hydrolic pumps etc off of the PTO or dump beds in the medium duty market. Think outside the box a little. Not to mention bailing hay would be sweet. But that was just a completely different subject not related to the truck transmission.sorry, you still havent sold me on it.

Why billions? Hell, why even 100 million? It's already invented. Why reinvent the wheel? I am sure it has been tested, test it some more. If it works, fine if not fix it and go back at it. How much is market share worth?

For what it's worth, the Stock Allison was aways a POS excuse for a transmission. When it came out it was sapose to be "All That," it was a joke. It has good hard parts in it but otherwise it's a failure. Even Allison themselves have done the transgo upgrades from the factory.

well maybe you should go to work for GM powertrain, you seem pretty confident that you could design a better and more efficient one.

So the Allison is garbage? I've had three with no issues.

Anyone put a power programmer on 6.0 and the Torqueshift and see if it goes in to limp mode. Heck look what the 6.4 are putting though the new Torqueshift. GM has a sorry excuse for a transmission from the factory when it comes to holding hp.

Why would GM think about people putting an extra 200 hp through the trans?

It holds stock power without problems, like it was designed to do.

 

[duramaximizer]

Why would GM think about having an engine that holds up well past 3XXhp and 6XX torque? Why would a GM design a front end or rear end to handle 500 hp and 1000 torque? Why does the transfer case hold up? Why does everything but the tierod ends and the transmission hold up to reasonable amount of after market power. Heck why do the turbos live at well over 1600 degrees?

Why wouldn't GM think about putting a transmission in that would hold atleast the hp that the motor is capable of producing? Why does ford put such good tranny behind a similarly rated motor?

I am just saying after you see/experience a good IVT transmission, you'll throw that 5/6speed Allison under a bus. (No pun intended.) You can doubt all you want, but it'll be like a 12 valve cummins guy convincing a duramax guy that the duramax is a POS. Eventually the cummins guys have no choice but to see the light.

Im in the dark here dont have any answers to your questions. You are the armchair engineer in this thread; enlighten us please.

Sure it holds up, but for how long? I don't see how it is GM's problem that you want to put more power through a truck's components than it was engineered to handle. Last I checked GM was still a company (a bankrupt one) but nonetheless, it's goal is to make a profit; not to extremely over engineer everything so a small percentage of people who buy their product don't piss and moan about a stock transmission not holding up to more than stock power.

Why wouldn't GM think about putting a transmission in that would hold atleast the hp that the motor is capable of producing? Why does ford put such good tranny behind a similarly rated motor?

If that's the case, why doesn't my Duramax come from the factory with a compound turbo setup and a Mike L trans ready for whatever? I mean its capable right? Just because it can doesn't make it GM's responsibility to make a 7k pound truck into a race car.

And I read about the transmission, it seems like a great idea. Will it ever come to fruition? Who knows.

 

[WolfLMM]

Guys, You don't honestly still think that the Allison is still the best trans do you?

The hard parts are nice, but it shifts like garbage compared to the dodge and ford offerings.

 

[duramaximizer]

I agree with all of you to a point, but just agree with me in saying that the future is not in a 6 speed allison, nor is it in an 8 speed.

I have been told by a friend....(not a friend of a friend) that the government has/had IVT trannies duramax's in the former iraq/iran war area.

Just more hear say. :happy2:

 

[Big Block 88]

We have 5 D-Maxes in our motorpool and all are Alli's. I'm not sayin it isn't out there but it isn't here.

You could be thinkin of the Comms truck GM and Ford made. They do have somethin different for a diesel/hybrid system they run but I am not sure what it is.

 

[Dzlnut]

I would buy truck with a IVT tranny in a heart beat , Deere tractors have them, farmers love them and the increase in fuel economy.

no, you are talking about that diesel hybrid/hydrogen system, the one that also has independant rear suspension.

And if your friend really did know something that secretive (and was truely "in the know"), he would be keeping it secret and wouldnt be telling you.

Sorry, still dont believe you. The IVT is YEARS off, if it ever even does come out at all.

[duramaximizer]

Didn't know anything about IRS but he did say it had quadrasteer.

Funny, I seen a 4.5 duramax prototype in 2003 and everyone doubted me on dieselplace too, and I guess for good reason.....it still isn't out yet. :rofl:


On edit what's in it for someone to keep secrets. Very few things stay secret with the internet anymore.

 

[Iceman56]

I have had an IVT in one tractor (7820). We sold the tractor within a year based on just the transmission. It had its ups, in the field it worked great but for handiness around the farm it was worthless. I don't think this would be a very fun transmission to have in a truck but I could be wrong.

 

[mmangels22]

The allison is a good transmission, if you want a trans to run 500 hp and 1000 ft/lbs, get an upgraded trans kit. GM/ford/dodge should not need to build a trans set up for the minority when the majority is where the sales happen.

To say the Allison is crap, WOW is all I have to say

It was cool when it was released. Now that everybody has caught up, its nothing.

 

[Big Block 88]

It's nothing? The way we tow I would say the Aliison is still king of towing. And with all the Duramax's in the 10's and 11's this year with an Allison I would say we have not fallin behind at all. It's not easy to stay ontop but give Allison time they have been the bench mark for years, they will come out bigger and badder than ever.

 

[Dzlnut]

I still think that the allison is king in a stock powered work truck, the 5r100 is pretty good but lets face it the dodge tranny is junk in stock form.
