the pistons are different, they have a different ring package, and bowl designed after the piezo style injectors, rail psi is up too i think it's 29.5k
bore and stroke is the same, cam is different,rods/ mains have better bolts
fuel system is all made around the injectors, turbo has 5 sensors on it, oil temp, coolant temp, turbin speed, exhaust psi, and boost i think...

Rear thrust, is better material, oil gallies are better, and jets are bigger.

if i remember more i'll post it up.

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.

YEAH, COME AND TELL MY BUDDY THAT, HE'S HAD 7 TORQSHIFT TRANNYS PUT IN HIS 03, AND ALL IT HAS IS A 400HP INNOVATIVE TUNE. OH, AND THE TRUCK ONLY RUNS A 13.9 IN THE QUARTER MILE, AND THE HARD PARTS COMPARED TO THE ALLISON..... WELL THERE IS NO COMPARISON. SMALL FREEKING PARTS

cool, so we will most likely be able to interchange more favorable LML parts (pistons, oil cooling jets, etc) into LB7/LLY/LBZ/LMM builds.

Yes the heads are the same with the exception of a smaller injector bore, but that can be machined, matter of fact im going to be parting out, or selling a whole LML fuel system, and other parts this week

Are the rods the same?? Any better??

Rods look similar, except the bolts are stronger

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

No one has caught up yet.

Interesting thread, wonder what kind of fuel economy the new LML will get? Tranny discussions are always interesting. I don' think any of the trannys are much good in stock form if you apply a lot more power above stock. I wonder if you pee in the, "diesel exhaust fluid" tank on these new dmax's it would provide enough urea to do the trick.

Good mention of fuel economy.

i was told that the new piezo injection sytem will be able to produce 15% more power (TQ and HP)with the same amount of fuel as the lbz/lmm,stock tuning offers, that would translate into more fuel economy

Maybe not hard parts wise, but shifting thats another story.

 

[Dozerboy]

Whats wrong with the shifting? It goes from one gear to the next just fine. I don't think the Ally is perfect but it still pretty damn good.

Have you owned the other trucks? I grew up drivein ford powerchokes, and Cummins trucks. There is a reason we went to the D-Max Allison combo.
My last R and R I pulled with a new 6.4 and the TQ shift. It was very nice but no where near as confident feeling as the Allison.

So you are sayin after all these years all the manufactures were wrong for usein the Allison in the HD platforms? There is a reason Allison transmissions end up ion the wide variety of vehicles they do. From the Abrams to School Busses to our GM trucks.

I didn't say they arent a good trans. Drive a new dodge or ford, they shift much better stock and modified. No I'm not saying they were wrong, they need to work on shift quality though. Never been in an Abram but school bus tranny's shift like garbage, so does the ally in my R.V.

The reason I drive a Chevy has nothing to do with the trans. Its the TRUCK I like.

It shifts kinda like a power shift in a cat dozer. And yeah its a good trans no problems with any of mine, except it could shift a little more friendly.

I really disliked the way the new dodge tranny shifts with a load on it compared to the allison. The Ford tranny feels good, but I do not think it is as good with a load on the truck. All trucks at stock power as they were designed to be run at.

 

[Big Block 88]

I like to feel my trucks shift. The newer ford and Dodges we have hangin around our barn shift way to soft and sluggish for my taste.

This is kinda ridiculous..."To ensure that the exhaust fluid tank is refilled, Duramax-equipped trucks will warn the driver when the fluid is down to a 1,000-mile range. A series of start-up warnings -- including lights, chimes and messages -- will become more frequent until the tank is empty. If the driver continues to operate the truck with a dry tank, after a final warning and restart the truck will only operate in a “limp-home” mode that limits speed to just 5 mph until the tank is refilled."

What if youre in the middle of nowhere with no way to refill? Or in a small town with on refill station?

Doesnt matter how far in the middle of nowhere you are, when the warning goes off dont you think its a pretty good chance there is a urea refill station within 1,000 miles..............

could be worse, the fords, dodges, mercedes, and vw's that use urea (the 2011 c/c and 4500/5500 rams will use urea, the pickup trucks dont use urea they use a fancier dpf) actually shut off and will NOT restart if you run them out of urea.

plus, pretty much all diesel stations will also sell urea....

 

[duramaximizer]

Bump to the top to see if anyone has anymore info on the new motor, and maybe an increase in turbo wheel diameter?

 

[duratothemax]

piezo injectors that run off of 250 volts, just under 30,000psi max rail pressure. Delphi fuel injection. Delphi ECM (99.9999% sure). 2 electronic fuel pressure regulators, no mechanical/spring pressure relief valve. Single turbo (basically looks the same as LLY-LMM, little different internals). 2 EGR coolers. Completely different pistons (federal mogul??). Slightly different rods. Little stronger block/crank. Heads basically the same (just different injector bores for the new piezo injectors). Urea system. NOx sensors. 4 EGT probes at various points in the exhaust. Hydrocarbon (fuel) injector in the exhaust to handle DPF regen. Fuel injection pump is now "timed" specifically with the camshaft. Driver side exhaust manifold no longer has that stupid pointless clearance/neckdown (no more market for the BD manifold now I guess!). Different PCV system with a CDR (like the 6.5's kinda sorta). Electric/ECM controlled fan clutch (I think).

I dunno what im forgetting..
