I've searched on this subject and found limited info on it. I know that a road ranger 9spd tranny (I think) will bolt up to it and should be able to hold the power and torque, but are there any autos that can hold up to the power of an 8.3 with soms power mods? How about some syncro'd manuals, like a NV5600? Thanks for any input you guys have.

The Spicer 6spd came standard in many medium duty trucks behind the 8.3. The only gears that are not synchronized is 1st and reverse.

I looked at the ones on the roadranger site. The max tq for the 6 speed is 860 lbs. Could it withstand more torque if it were in a lighter truck, like a first gen dodge? Any other trannys that could withstand lots of torque? Any heavy duty autos? It may sound dumb, but I've been thinking about swapping an 8.3 into my '93 for a fun project. Of course some mods would be added, first being the TST kit which adds 150 horse and 300 tq.

Edit: Monty, I'm assuming this is the line of trannys you were talking about?

Anymore input?

A local tandem axle garbage truck with a Cummins has an auto, Allison I assume. Most Garbage trucks, firetrucks, etc run the Allison, it should hold, those guys are murder on equipment. A lot of the big rig pullers run the Allison also, with a lock up switch.

the army 5-tons have the 8,3 w/ allison 5spd. they so allright. we have some in our iraqi battalion, and they dont do a lick of maintenance. they hold up for now.

Monty

Yessir, those are the trannys. They might not be a good idea to run if you are going to be adding more fuel. The older mechanical Allisons may be your best bet.

Thanks for the info, everyone.

I'd definitely be adding more fuel. Can the older mechanical allisons hold up to more power? Anyone have any model numbers I should look at?

the 6spd allison in our 96 safari motorhome does awesome in front of the 8.3 cummins.

is the 8.3 phisically bigger than the 5.9l in appearence

can one fit a 8.3 in a dodge with out much work needed, thanks

I've read that it's about 4" longer and a tad bit wider. Not sure about how much taller, though. I want to put one into my '93, but the main problem I am having is deciding on a tranny. I'd probably have to run a divorced T case.

It would probably be easier to fit in a first gen, since it seems like they have a little more accessible room than the later models.

the 8.3 makes the 5.9 look like a toy. i have each sitting side side. if i knew how i would post pics.

w/ the detroit series 60, which can be aound 500 hp, we have the allison ev4000 i think with the detroit 40, which i think is very similar to the dt466e from international they can come with the ev3000. all seem to work really nice but they are also autos

Those yard mules they use to move trailers around lots and stuff have some
8.3's in then and they had an allison behind it. Not sure of the model # or anything, and yes the 8.3 is bigger. We had them with a 5.9 and 8.3 and there was a big difference in size. Good thing about the 8.3 is the removable liners which made overhauling them a snap, just pop the head off, oil pan, pistons come out and pull out the liner. Wish the 5.9 was like that!

You could find a place that sells those yard mules and just browse around their lot, pretending to be interested and crawl under it and write down the model #. Or just email allison and inquire, they would probably help you out.
