What will a stock Trans hold?
 

My buddy is looking at an lbz is the near future and has all the plans for what he wants to do but he hasn't thought of a Trans upgrade. I'm a dodge guy but I know the Allison is a bad ass transmission and I'm wondering what the Trans is capable of handling before he needs to build one

Yep its badass, but it can only do so much for so long, once the engine is modded....like any other truck. Will also depend on the mileage on that rig as well as the maintenance intervals, and abuse or the lack thereof etc. WHat is his intentions?

I think just to have a quick street truck. We both plan on doing a little track racing but general purpose we will both still pull small trailers. And daily drive. He just wants a Duramax that will compete with my dodge so it'll be in the mid 400's or 500's

At that point just do the trans and don't even question it. That kind of power will toast that trans in a hurry.:pca1:

Bout 100hp total is all it will handle for any length of time.

Mine did great all the way to 300k with a light tow tune and grossing over 30k frequently. I had a Mike L cooler kit, amsoil torque drive fluid drained ever 30k, spin on changed ever 10k, internal changed every 100k. Saw 300* a few times. I could limp the converter loaded heavy if I stomped it in 2nd, unloaded it wasn't an issue.

Google tends to be allot faster than forums for easy questions. 1 ft lb after its rated input torque and its life is in your hands. :pca1:

Allison 1000 Transmission - GM Diesel Trucks - Diesel Power Magazine

Attached a pic, just sayin.

Everyone on Google has a different opinion I was hoping to hear from someone with more experience than me. The only thing I know about auto transmissions in diesels is that dodge can't make one

Only pointed you to google cause you asked what a stock part will hold, everything has a tq rating and allisons are bad bitches, they will run at rating all day everyday and love it. Always wondered if dodge trannys would have a better record if yall listened to their tq rating :humm:. Im just as guilty as everyone else as running my shit to hard but I only exceed the ratings of things I can afford to replace :choochoo:

The 48re is a good sturdy trans, however the cummins is a bad mutha and will easily over-torque the trans, especially if ya add hp to the cummins, then the trans is just a ticking time bomb. IMO, a well built cummins, mated to an Allison, and stuffed into a ford super duty would make the ultimate truck. I know, I know this post has no relevance......just ranting. :w2:

Haha we have a pretty slick fummins Rollin through our town but it's got an nv5600 instead of an Allison. It'll blow your mind first time it passes you then you'll see the Cummins badge

Why does everyone want to put a cummins with a allison in a ford body? They are ugly as shit as far as i can see. :loco:

Most durable motor withe the most durable transmission in the most durable pickup. It's like taking the strong suit from every brand and combining it

Thats debatable. :bat:

What's debatable about that? I love Chevys and if I had to have a gasser it would be a Chevy. If I was tighter on cash I'd have an old ford with a 7.3 but instead I have a 2003 Cummins because even though I have fierce hatred for dodge there's no debating the Cummins is a beast (not in Stock form of course) but yeah

Cummins is good and as a company they build some badass stuff, but its not any better than a dmax. And there isnt anything more durable about a ford truck body.

I'm definitely not knocking duramax I've been around some great ones but also a few absolutely terrible ones which is why I couldn't risk buying one. My brother owned what was probably the toughest lmm ever owned he ran a bulldog gt for nearly a 100k miles on the high setting or the extreme. Mechanically sound and trans lasted 94k miles with the tuner and about 100k before that when it was just deleted. Then my other brother had a new 2013 and I'm assuming it was a cp4 problem but went through a driver's side fuel rail every 7-8k miles and he got mad and finally ditched it when it nearly cost him a pickup and tractor when he couldn't pull a tractor out of a burning field and the pickup just died and wouldn't start thank God the neighbor had powerstroke and was able to pull both of them to a road before shit got to bad but that pickup got fixed and traded in the next day and he went back to Cummins

Both engines have known issues, every engine ever made does. There is no way around that. Lets just agree they are both equally better than any powerstroke ever made and call it a day :c:

You have to give that when powerstrokes run they run like a bat or of hell, but yeah I can't give them the reliability that's there with a cummins or Isuzu

anything -anything- can be fast. :pca1: some engines just make it easier.

My 6.5 will never run with dmax's or cummins. But 250k miles later its on its second truck :rocking:

As i was typing that i just realized both my 6.5's have 250+k miles on them. cant say that about my 4l80e's lmao.

The cummins is a hell of a lot less complicated than PSD or DMAX, PLUS it has less moving parts and its so darned narrow that you can actually see the engine block, belts, fan, and virtually all of the accessories. AND, (I cant believe I just started a sentence with a conjunction.) you can easily get to them if ya had to, without taking things apart jus to get to them. Am I right?:w2:

Yup, not sure that makes it better though :humm:. Just easier to work on when your programmer blows it to hell :bat:

The 6 speed Allison can run a 120 tune(as long as it's a good one) for a pretty long time if you don't beat the the hell out of it and watch yourself in 5th and 6th gear and can run a 90 tune without any restriction at all. Past that you may as well avoid disaster and get it built first.

Yep. LOL, never figured it that way...........but ya got a point there.

My dad's '13 Cummins isn't more simple than my '13 dmax.

Amen to that. working on all these new computers under the hood sucks ass but they're so capable of making power with simple mods

Well I had a H&S XRT PRO tuner set on 80HP on my 2008 F-250 6.4 5r110 tranny at 62,000 miles till my truck was stolen with 109,000 miles & my tranny was still running strong. So it's safe to say that it should handle at least 80HP:humm:
