just seen that posted on the ford site this morning... good for gm. . they will be 1 up on ford, and 2 up on dodge dodge needs to get on the ball and get them aisin 6 speeds in the works quickly...

 

[zstroken]

what aisin 6 speeds are you talking about?

 

[HoleshotHolset]

The 1000-series Allison has had 6 forward gears all along, right?



If I'm not mistaken... now they've just enabled some software to let the last one loose...

if you go to the allpar forums, there is rumors and order codes for some aisin 6 speed automatic... looks about the same size as a allison 1000 [or maybe a bit bigger] i think it is a double OD transmission, so it would need to come with 4. 10 gearing in the axles...

Those are just rumors unless something drastically changes at the DCX place.

That’s what an Allison tech told me two years ago. All you need is the program for the planetary to engage a different way and then you will have a super low OD (I think super low or really high??)



I am thinking of jumping on the Allison bandwagon. (No not going to buy a cheby, just swapping transmissions)



I agree, Dodge needs to get on he ball with the auto.

What have you dredged up on the swap?



$, custom parts, labor?



sounds interesting seeing as a Ats is btwn $3k-5k

Just brain farts over beers… I have a buddy that works for Smith Detroit Allison and is very knowledgeable with the trans.



I would go to a junkyard and find me a 2003 or later m1000 and complete wiring harness with all the necessary computers and sensor. (out of a G M C or a cheby, diesel of course)



Then call advanced adapters and get all the adapting parts and then start ripping and tearing.



BUT, I would call Piers and talk to him first about the conversion. I saw on his website that he might have performed some work on one.



I guess its nice to have friends in the right places.



$ = I am thinking around 2 g's for the trans, maybe a few more hundred for the adapters.



Labor = Beer plus more beer



Info = talk to piers and the allison guy.

forget the allison. mercedes is partners with dodge/chrysler. mercedes makes trannys for tractor trailers why can't they make them for the dodge ctd? :{

 

[Farmall Hauler]

I've Also read on one of the two major Ford sites where the Ford 5R-100 also has the ability to have 6 forward gears! I'd have to do some digging to find it!

"Constant communication and feedback between engine and transmission" ... man that thing sounds like a nightmare for the owner and a money-maker for the repair dept.



I like the "constant communication and feedback" between my feet, right arm, and brain ... ain't no other machine that works quite like it ... now if we could just get a 7 or 9 speed manual.

It's about the same amount of communication (over CANbus) that goes on between the injection pump and the ECM in your VW TDI. Don't be afraid of technology - embrace it and use it to your advantage.

The common misconception is that the allison is a bullet proof unit- it is not Ive seen one puke with one box on a dmax- to have a high hp dmax, you have to spend the big bucks upgrading the allison- just like you do the 47/48re. I'll take the full billet with a triple locking converter from anybody before I wnt through the hassle of swapping the allison in and still having to build it.

One of the main reasons the D max's are quick in the quarter to the advantage of having more forward gears coupled with better ratios.



When I pull heavy I have to either go 85 in od or 60 in drive to keep the rpms "in the sweet spot" The only other way to fix it woul dbe to add and over drive unit, but i have heard they do not fair well at my power level.

Holeshot, I'm in the computer business and boy are they problem prone. Yeah the VW has some computer stuff that you need the VAGCOM to monitor/modify. One of the reasons I will never buy an automatic is to reduce the "computer" equation. The less computers are involved, the better. There are some things that we should not "embrace" with enthusiasm (like TV ... my wife and I got rid of it 3 months ago ... what a difference). The more complex the more error prone ... thats just the way it is.

UMMmmm - what's the difference between a Taiwan made 10K 1/4 watt resistor in a $4. 95 Kmart transistor radio - and that same value component in a $1500 DC ECM?



Answer:



None, zero, nada, ZIPPppppppp!



And when that . 02 cent part fails in the radio, you simply get silence...



And when it fails in the ECM, you also get silence, and probably a long walk...

FATCAT, Gary - K7GLD:



You guys crack me up. :-laf



Gary's an Extra class licensed ham radio operator. To pass that test, you have to acquire quite a bit of electronics knowledge.



FATCAT admits to being in the computer business.



Both of you guys are worried about the very simple electronics inside of an automatic transmission... yet are probably quite capable of figuring out the electrical innards of an automatic transmission. People usually fear what they don't understand... I think you guys understand auto trannies - so... why do you fear them?



No flames intended - just trying to see what you're getting at here.

Never had an automatic that lasted more than 60k except my father's old '71 Skylark with the THM350.



The only automatics I like are belt feed :-laf

It's exactly BECAUSE I am an Extra Class ham, and former Production Manager/computer systems administrator at the daily newspaper I retired from, that I *fully* understand that the most fabulous and state-of-the-art electronic device in the world is NO better than the weakest and poorest quality component in it's circuitry.



A burned out 2 cent resistor (even in a "simple" circuit!) will leave you alongside the road JUST as fast and effectively as a thrown rod or trashed transmission. How many reading this still have a 10 year old TV or stereo system in regular use - and if you don't, did you replace it because of a failure that was too costly to be worth fixing? How long do you expect to keep your current vehicles, with THEIR heavy reliance upon electronic controls?



I owned my previous Dodge/Cummins, an *almost* electronic-control free '91 model for 11 years - and only a *single* failure sidelined it in those years and 120,000 miles. And THAT failure was a "simple" $12 solid-state voltage regulator! For all the motion I got outta that dead truck, it might as well have been the motor itself!



There is very LITTLE difference between many of the individual components inside an ECM or similar vehicle control device, and those used in the CHEAPEST radios and TV's.



No, *I* don't "fear" this stuff - but I *do* respect the inherent weakness they contain, because I *do* work on this stuff for fun, and in the past, for a living!
