I had been thinking of this swap for about a year and a half , but others I had talked to thought it was a stupid idea or thought it wouldnt work. I figured it would work just to get the little things figured out . Takes a lot of time and thinkin. I am surprised of the interest in it. I do think it is a better trans and the gearing is spaced better. I like the thought of being able to switch modes from street to pulling and with the heavier built internals it should outlast the truck if not serverly abused. In my experience over the years and many many pickups both manual and autos, I have had way more problems with manuals than autos and as a matter of fact I never had a problem with an auto until this 47RE. I have pulled many extremely heavy loads over the years, way more than I should have, ummmm farmin business thing ya know, and the have grenaded manuals but the autos hang in. So that is why my interest in this swap. The owner where I work now Is hard on things and he has torn evrything up but the tranny in his D-max and all his big trucks and over the road trucks have the allisons in them and I can tell ya they get a severe beatin and keep goin . This is my opinion and my experience and why I have an interest in this swap. Im glad so many have the interest and Gabe is so helpful in understanding this . Many thanks guys . Great site. Keep the comments comin!!

TORQUE... I am not trying to be cocky or anything like that but there is going to be numerous drawbacks to an Aisin tranny. Nobody knows how it is going to hold because they are not proven. Yes it will bolt right up, but they are electronic so how or who is going to program that tranny tailored to someones truck? They will not just start working in our trucks without some software modifications. Who works on Aisins? They are a Jap tranny and I don't know of anyone that works on them. This is not by any means meant to be a mean post or anything of that nature. These are just questions people would need to know.

None of the other electronics on the truck are bothered. The TCM is stand alone so it doesn't need to interface.

No offence taken Gabe32, like I said I wish you all the luck, seems to be a lot of interest. I don't think you will have much to worry about yet for a few years. By the time it is out, and shows it's weak points(which it will for holding big power like some guys on here now have
), and aftermarket kicks in with parts, you should have your foot firmly in the door on conversions here. This should give you a 18-24 months headstart, and give you time to work out the bugs, do quality assurance, do dyno# comparisons for hp/torque, 1/4 mile difference, and durability testing. These will be crucial for marketing your swap, if it proves it is better than a built h.p. 47re or 48re now.
Someone I suspect within that time frame, will come along and do exactly what you are doing now with the Allison swap(maybe it will be you if you jump on it)
. Although it should be a little easier, and maybe with cheaper parts and labour MAYBE-MAYBE NOT (hard to tell yet), to adapt the Aisin 6spd to the older style Cummins.
Daimler/Chrysler will have the technical support for techs in place, before these trannies are released to the public(J-Body for instance will probably be one of the 1st to post info on it-don't you just love me putting you on the spot like that J-Body)
.
Now if you would like ME to be a BETA TESTER for your swap in Canada , I'm all ears, and would give it one heck of a constant daily workout playing and towing, especially once I add the TST fueling box very soon. Good Luck

I dropped out of the "transmission scene" when I move to AZ 9 years ago as they already had a trans guy in place so I really don't go to training on the newer stuff anymore. If the Aisen trans for the CTD is HALF as good as the unit they put in the Jeeps people will be satisfied.

Will the Asin bolt to out 5.9? Or are we just assuming that?

Here is our earlier exchange.
that is a argueable question. I will say it like this: The allison in STAGE 4 form, I would say is stronger than a stage V ATS. I have sledpulled this season with mine and it never broke or slipped. I know of several ATS and Suncoast trannies with billet shafts that have busted. I am not talking bad about there trannies but there is only so much room to work with the 47 and 48re trannies. The shafts are too small and that is why they still break the billet ones. Do a search on "broke billet shaft trannies" and you would be kinda surprised at how many break. I am not trying to start a war by any means, I have had both trannies and the allison is by far the much better tranny. THAT IS MY OPINION!!
