with the high cost of a clutch seems like maybee a cost effective change???

tool

Oh my!!!!

Clutch = $500 parts +

Alisson................. Aleast $5,000 parts????? Plus all the modifications you'd have to make.

Mcmopar

Yea, and then you mod the truck and the allison is a pile of broken parts!!!

amartinson

Very true. We have several Duramax's at work with the "Allison" transmission and they are unimpressive to say the least.

People think heavy truck trans when they see Allison, but the trans they are putting in these trucks are an Allison by name only IMO.

ok what about changing to an auto 48re or whats the hot bd or diesel tranny these days...might be easier to buy a 01 auto and swap my hot parts over...

bws

sb or luke clutch is 1000.00 or more i think for my hp/tourqe[which i have no idea what it would be]she runs good and the milage is awsome[if the computor can be trusted??]

Mcmopar

You can find a 47RE pretty inexpenively and send it off the be BOMBed, or I have seen new 48RE's for just under 2K new.

The computer can't be trusted, especially after adding the comp and injectors. Start calculating your MPG manually and you'll probably find that you are 3-4 mpg below what the overhead console reads.

bws

ya, thats what i thought 23.6 average was pretty good...i just filled up and will calculate milage.sure like dealing with rip at source automotive,scotty's no more business....jmho

mr T

the alli is a complex computer tranny....ud need extensive comp work to get the engine and alli to work together consider that expensive....then throw in lots of hardware...umm lets see...everythign from the flywheel on over to allow the tranny to bolt up right....different tranny mounts....different transfer case..perhaps driveshaft changes....gonna cost u a few grand...u can get a hopped up 48RH that will take alot more than any allison can

whats the big thing with going with the 1000 series allison?? its the base model it maxes out at 590 torque (website) and replacement parts or beefier parts cost u more than some used trucks!

heck id love to go 5 speed so if ur gonna do this then please let me know and i'll drive down and pick up the tranny thats lying on ur driveway

ATS has a stand-alone controller for the allison transmissions now. You can find a used allison out of a wrecked dmax and there is a bellhousing to mate the two. Overall a little more money for a build up allison and the controller then to just build a 47RE. One of our project trucks is probably going to do the swap to the allison pretty soon.

I would be more than happy to take your man trans off your hands!!!! And I wouldn't even charge

PourinDiesel

Yeah, throw in the Allison. Its the toughest tranny in the universe, it could probably handle 1000hp.

powerchokeater

I would consider trading you my auto and all the parts you need for your trans with all the goods

If you want the Allison don't get the 1000 they have on Duramax, get a 2000 or 2400 they will stand a lot more power and torque.
They make adapter plates for them very easily, since Cummins installs their motors (ISBs) on many commercial trucks.
Installation on your motor is not a problem, they also come with it's own TCM so they are independent. Only place you will have to look is adapter for rear output, since commercial trucks are all 2WD.

I know all this since I just sold a complete setup 2004 ISB Cummins 215 with Allison 2400

My suggestion, get a nicely built Goerend or Suncoast transmission.....
