Allison auto

[young_gun]

I have my doubts, but would the Allison pickup tranny bolt up to a 6.5?

[sixnickel]

The bell housing bolt pattern is the same that is the easy part! But how are you going to controle it ??????

Allison tranny into a C/K Truck ? Why not complete with a duramax engine ?

As much as I'd love a Dmax, I don't think I'll get my hands on one for a while. I was just looking for a new tranny and came across an Allison and thought it would be cool if it would work in my truck, and wouldn't be too much work. Everyone who I've talked to about the Allison just loves them...I've never heard anything bad about them.

There is a standalone controller for the allison 1000 transmission, they used it on xtreme 4x4 when they built the suburban gorilla. All you need to give it is +12v. It might be pretty costy though, probably comparable to fuel injecting a carborated engine.

There is a guy in Edmonton Alberta that will put a DMAX and Allison in your truck for about $20,000 cdn complete

That's about $16-17,000 US. For that amount (if I had it) I can get a used 2001 3500 Crew Dualie 1-T D-Max with about 100K mi on it here in Lincoln.

Aside from some major alterations to the firewall and transmission hump/tunnel, which version(s) does it work with, 5 or 6 speed, and who manufactures it?

I too have access to wrecked D-Max's with Allisons. It would be a neat upgrade to replace a 4L80E behind a totally built 6.5, but then what would you do with the ECM not able to talk to the 4L80E? Use a 92-93 spec engine and lose all the electronic hop-ups to the engine? Or, perhaps using a 94-up manual so you don't have to interface with a tranny? I don't know, I don't know the computer well enough, but the idea of an Allison behind a 6.5 intrigues me. Anyone out there up to the challenge?

[njdevi11]

I dont know the details but it can probably be found by looking on their website http://www.truckstv.com/sites/xtreme/ Look for the suburban gorilla, I have most of the episodes on my tivo and can burn them to a dvd and send them to you if you want.

If you have a wrecked donor, then it should be straight forward. you can use the factory computer. Take absolutely every wire out of the vehicle and put it in the new vehicle. I'd be willing to help on this project. I am very good with automotive electric and up for any challenge. If you want to swap the 6.2/th400 in my cj for a dmax/allison ill put it on the butcher block, ill just need to un-box my frame i guess :-D

D-Max wont fit in our trucks, way too tall. The standard upgrade is dropping in a 12 or 24 valve 5.9 Cummins commonrail as its computer is attached to the engine. I'm just intrigued with the idea of putting an Allison 1000 behind a built 6.5 and gaining a much stronger tranny than what the 4L80E could ever dream of being, with another overdrive gear to boot!

WHY SHOULD IT NOT FIT IN OUR TRUCKS ??? Look at the links i posted in RED in my post above ! THE DID IT ! THE D-MAX AND THE ALLISON 1000 WILL FIT !

Well, i took a look on http://www.powertraincontrolsolutions.com/ and it says that the Allison 1000 is currently "under development" they probably got a pre-production version of it on xtreme 4x4 for their project. It might be out soon.

My CJ has a 2" body lift and about 6-8" above the 6.5 intake, i could probably fit a dmax in there.... on day maybe. I still like the idea that there is no computer anything in my rig though. It's a machine in its purest sense.

[bigcountry]

The way I understand it GM had to put a 2" body lift on the first GMC's with the duramax/allison so it would clear the tranny

Your right, Sven, they did "stuff" a D-Max in there. It does; however, require extensive modification/fabrication of the front crossmember (2WD), diff mount (4WD), frame, engine mounts, and radiator support to get the engine to sit down low enough to fit under the hood, as well as firewall/tranny hump mods to clear the much larger Allison. These are the "little things" that they don't tell you or gloss over in those magazine articles to ruin the "gee-wow" factor.

Now the interesting thing is that the Dodge Cummins ISB will bolt to the 4L80E! Yes, it does using the Cummins adapter for the 4BT engine used in GM delivery step-vans (ie: Frito-Lay, UPS). And, it will fit in our trucks. Diesel Power a few months back had a feature on a guy who dropped one into his 96 4x4. It did take some interesting "backyard engineering" to get the PS, PB, AC, and a couple of wiring harnesses to interface, but you would have the same problem with the D-Max.

Again, I was just intrigued by the idea of putting a totally bullet-proof tranny (A-1000) behind a built 6.5.

P.S. I did click on your links the day that you posted, Sven. The extensive modifications is why the vendor in Edmunton, Alberta charges almost $17,000 U.S..

Okay, than i didnt' said anything ! :D

But who wants to put a six cylinder diesel in a truck that you get with an 8 cylinder ? If i wanted only six i had bought a girlie-man-truck like a dodge.

See attachment - it's only my opinion !

You've been watching too many Saturday Night Live reruns of Hans and Franz and we're here to pump you up! Seriously though, Sven, the ISB's can pump out a reliable 500 HP and 900 lb/ft of torque with only a few mods. Not bad for a 5.9 litre six-banger, and in full race mode, they are getting over 800 HP and 1300 lb/ft!! and turning in low 11 second quarter mile times at 120MPH and doing it in street legal 1Ton dualies! So are the D-Max's!

Don't get me wrong, I love my 6.5, but I know it's limitations, and there are those who just feel the need for speed with diesel power. Just letting you know what some people are doing out there with their Chevy's.

I know, what you can get out of a cummins, but i don't like sixbangers. Only V8 is the "real" engine for me and i know the limitations of the 6.5 also. If i want a diesel with power i would take a D-Max. I know somebody putting out 813 HP at rear wheels in a D-Max and 11.45sec. on th 1/4 mile.

Would that be 11.45 sec in the .4km? The only limitations to the 6.5 for making serious horsepower are the rods, heads (IDI), and injection system. I was thinking the other day and here's what I came up with. The 6.5 and 6.6 are very close in their bore/stroke. Rework a set of D-Max pistons to fit the 6.5 bore, and have Childs & Albert make a set of forged steel rods that are twice as strong as 6.5's that fit the 6.5 crank and 6.6 pistons. Develop new DI heads for the 6.5 that use 6.6 injectors. Replace the TTY headbolts with ARP studs. Redesign the exhaust manifolds for better flow, especially the pasenger side. Use the D-Max injection system (stand alone engine management for the D-Max will be out by the end of the year) so all aftermarket tuning mods will work. Now we can have 800hp 6.5's!!

This was the next step in the 6.5 evolution, as both the Cummins ISB and 7.3 Powerstroke started out as 2-valve IDI engines that were developed into 4-valve DI engines.

Instead of taking the next step, GM dropped their diesel division and bought out Izusu's R&D on the D-Max as the easy way out.

Yeah, this sounds good theoretically. But could it be possible in real for affordable costs or would it be ceaper to buy a D-Max or put one in a C/K Model ? Look at this site and the videos from Brandon :
