Allison transmission

[MMcCallie]

You're right GMac, i don't see anything about the TCU on the ATS website. I'm almost positive they used to offer one with their label that they purchased from powertraincontrolsolutions.com. My buddy has been working on putting a Cummins and Allison in Clint Cannon's Super Duty, he occasionally makes parts for ATS. Both of their trucks have late model engines. Could you PM me your contact info that i can pass along so these guys can get their transmissions to shift as well as yours?
Thanks,
Matt

The allison doesn't hang any lower than a 47re does. They are a bigger transmission but they don't hang lower. When you have it programmed right, why do you want to manually shift it. For that matter, you might as well have a 5 or 6 speed manual.

Gabe, I don't know if you saw my post on the last page but would an Allison fit under a 2wd shortbed truck? And can it be made to work with a 12-valve?

huh... i need one!

 

[LanceD]

how much power can a stock allison handle behind the cummins? I want to do this swap but can't afford all the goodies to go in the trans yet.

 

[Scrappy]

it will cost as much as if not more to do the swap versus building the stock trans

powertrainsolutions is no more. I am pretty sure the company is out of business. They never had a allison controller that worked. Vaughn, it will work with a shortbed and 12 valve. If you read my sig, you will see I am running a 12 valve now.



A stock allison will hold up to about 500hp with stock clutches. I still would put a transgo kit and a triple disc in it.



An allison conversion is more that a built 47re but you also get more with it. You get a new crossmember, 5 gears, a transfer case, and piece of mind meaning you don't have to guess when it will shift. It will shift the same everytime and just the way you want it. It still is as strong as a full billet 47re.

Thanks Gabe- I didn't even read your sig!

I wouldn't mind spending more than what a 47re build costs all because of the gearing. Totally dislike the huge RPM gap between 3rd and OD, and the high 1st gear ratio (harder to get a load rolling). Since I'm not looking to go beyond ~350-375hp I don't think I'd need to build it much or need a triple disk TC.



I did some looking back at DTR, is the final drive ratio of the 5-speed . 74 or . 71? . 74 is what I would want. . .

I see the 1000 has the . 71 OD ratio & the 2000 series is . 74: Allison 1000 transmission - Wikipedia

I would think the 2000 series would make a better towing transmission since the final ratio is close to the NV4500's . 75, and you could more easily jump back and forth between Drive and OD.
NV4500 transmission - Wikipedia

When I tow with the stock trans taking the 2-lane highways around here I'm either revving to 2500 in Drive or lugging at 1600 in OD. With the . 74 final drive ratio I can tow in the low 60s without lugging it, currently anything under 67mph in OD = lugging & high EGTs.

Vaughn the 2000 does not have a praking pawl the 2400 does. The gearing is the same on the 2400.



I am currently try to scrounge up everything needed for a swap.

 

[LanceD]

wait, so you guys are saying a stock allison 1000, or 2400 is as strong as a full billet 47? or what kind of $$ do you have to put in an allison to get it the same or stronger?

 

[Philip]

In stock form it might not be quite as strong a full billet 47 whatever trans.



But it has other options that you won't get on a Dodge trans, built or otherwise.



It has a lower first gear, for us people that tow a 3. 60 something first gear sure would help getting a load moving easyer.



The ally has a lockup converter. It locks in second gear. Unless you throw a toggle switch on the Dodge it locks in around 45 MPH if I remember right. The ally stays locked on downshifts to 2nd.



The ally has engine braking. The Dodge doesn't. You can use an exhaust brake on the ally.

6th gear (0. 61:1) can be enabled on all LCT-1000's... the kit is a little spendy... but might be worth it for some folks. I'm going to wait and see how mine runs with 5 forward gears before I get the kit, though.

With my 3:08 geared axles I don't need 2 OD's. :-laf:-laf



Thats why I forgot to add that upgrade.

 

[KPaulini]

I would love to do a swap in my 2005 2500. How much does a swap cost and where can I get it done?

This Thread works much better on this forum

Good thing to point out Philip. I'm guessing a 2400 would be harder to scare up than a 1000. I wonder how hard it would be to swap out the OD on a 1000 to the . 74 ratio?

 

[Philip]

I haven't seen a 2400 on ebay yet. There are quite a few 1000's come threw there. I am not going to waste my time calling around to the local wrecking yards. They seen to think everything is solid gold around here.



I don't know what would be needed to change the OD ratio. Gmac would.

 

[MikeDee]

What is the real cost to build a 47re all tricked out. And what is the real cost to doing a allison swap that will take on 600HP?

I am curious in the price also. I have a NV4500 and I'm getting sick of shifting.

I know you can spend $6000 and up (depends on builder) for a full billet 47.

 

[GMac]

price is comparable to a fully built 47. It is obviously more, but you are also getting more. The allison has to have the 261 or 263 tcase behind it for a sensor. the dmax case is stronger than the 241hd.
