I want that transmission in my 99’ 2nd gen Cummins!!!!!! How much??? $$$$
Spotless.
Hey could you guys do a comparison video on the differences between the two Allison series 1000 vs 2000, I thought they were just physically larger but you put a 1000 tail on the 2000 making me even more curious about the differences.
@@Matt-fw3xw We can sure help you with that, we have everything needed to do that conversion behind your cummins, give us a shout.
Red paint on an auto trans gives you the extra HP well also fixxing any leaks!! genius
So that's why mine has more power, and doesn't leak... Always wondered.
It's awesome to see those guys putting your transmission together with ease, definitely some talented people over there at Xcaliber! Their machine work is superb and the in-house dyno is awesome
Yeah. You can see, that theae guys know their transmissions. Pleasure to watch. Easy to see, that they have done soooo many of these.
In the first shot of that walkthrough I saw their DMM and was like holy shit!
I have seen a lot of complicated amazing machines in my life but the automatic transmission still ranks as one of the most incredible in my opinion.
Mad respect for leaving the id tag inside the transmission with information and company name. You know they take some real pride in their work if they are willing to do that.
Sir, this might now be my favorite youtube build of all time for many reasons. Please make a full length on this!
Those dudes at Excalibur don't smoke a fat stogie...I'm not sure I trust em! Hahaha peace!
Joe is shaking his head right now
It's funny that I remember exactly what you're talking about.
Ash is an additive is some oils... some add a bit more.
I dont trust them just because I just watched them build a trans completely dry with no soaking of the clutches or pre lube assembly.
Eccentric Smithy it was just a dry fit for the video demo so they wouldn’t make a mess. They do soak everything. They also fill the units on the dyno and drain them to remove any break in material which many trans builders don’t have the ability to do.
After seeing this video, you just answered a ton of questions I had, & saved me a ton of legwork. Bought an '04 Freightliner bus/Cummins/Allison, for my upcoming Dodge project! Thanks again, stay safe!
Thanks Xcalliber transmission for taking us into your shop and showing us how’s it’s done. 👍🏼.
Nice build, I live in CT and didn't even realize they were here. I've heard if them, good to know its local for my duramax Trans when it needs it
The sheer *number* of parts in that trans is mindblowing and, presumably, leaving *one piece* out could wreck the whole thing?
I've got a Allison 2000 in my 2005 International IC CE300 dt466 school bus.
But this Allison 2000 is absolutely Beautiful ❤👍
Maybe some day??😗
I've so so much respect for the dudes who have to learn how to & design the pathways for the valve body
Allison fan since the beginning of time! Great video, I know it will give you years of service. Thanks for the behind-the-scenes look at a class act!
Awesome, I have a 07 Allison 1000 i want to rebuild and put behind my 12 valve that will all be swapped in my 1993 Suburban K2500.
Thank you for your videos. They’re very informative and entertaining as well. They keep me going, wanting to improve my junk. I have a 2001 2500HD w/ 6.0. I’m on second engine and trans. The originals are in my garage awaiting rebuilds. All together, it has well over 500,000 miles. Electrical in dash cluster went out years ago, so I don’t have exact numbers. But between my dad and I, we’ve gotten plenty out of this truck since he ordered from the factory, new.
I live not far from The guys that did your transmission and I have a couple buddies that have used them and I’ve heard nothing but good things. You’re in good hands with that one!
Last time I mentioned an Allison my wife came after me with a rolling pin.
I know nothing about anything you do or talk about, but I am fascinated watching your videos.
That's me too, pretty much. It's amazing what you can pick-up though, if the people you're watching know what they're doing *and* know how to put it across in a way that can be understood by those with less knowledge/skills.
We are pampered with the quality content deboss garage puts out.
When are gonna start putting it together I'm dying to see it
Engine will be done this week. I'll likely bolt them together and get it running on a stand to figure out all the wiring before we get into the truck
@@DEBOSSGARAGE That sounds oddly professional... Are you the guy that's been polluting Sloppy's mind lately? ;)
That guy Ryan at Xcalliber really knows what he's doing 👍great content, cant stop watching! Keep it up fellas
The torque converter replacement is good to keep contaminants out of a new build...so remember to flush your radiator trans tank and lines as well...just to be through.
MD 3060, MT 643 were good units in school buses many went cradle to grave 200,000 plus . PTS 2000 not so good had to have with electronic engines. The AT 540 ,545 we almost put quick connects on them. We kept one in stock. Of course the AT was cheaper when the buses were bid and they were replaced many times over the life of the bus . Really a nice looking rebuild.
Very nice, I was glad to see the Allison's internals.
The music choice is always top notch 👌👌
Excellent video, great footage and voiceover/explaining what parts are going where
transmission guys blow me away! all those parts man
that was cool, great job xcalliber and DG.. loved the allison animated stuff too 🍻
Don't know about you lot but the thing that got me hyped at the start was the engine but I'm actually more hyped about the interior than anything else since it'll be one of a kind.
Special shout out to the post production team. Really good video.
That’s awesome, we use dartco transmissions at work, but I’ll keep those guys phone handy. Good to know they can also do modifications 👍🏽
From experiences in a past life (10 years ago now, so things change)... School buses, at least in the US, aren't actually derated (maybe you're talking about transmission calibrations specifically?). It's up to whatever the district decides to put in their bid spec. If they said 500hp, OEs would package 500hp, somehow... Man would I have loved for that to land on my desk back in the day. 15L in an REBus? Hell ya, brother! Get ready to lose about 4 rows of seats and gain about 12 radiators, but it would be worth it. The power limitation on most buses is cooling, but on a conventional cab it's the same as a truck so 300hp+, the same as any other MD, was a standard option in them. In FE/RE, the power usually had to go down because you just couldn't cool it. Believe or not, you could order a CE with a PTO too if you wanted, though I'm sure you're right that no one ever has.
Oddly, I was told that it's actually _illegal_ to derate the power of a school bus or emergency vehicle in the US, by way of engine protection anyhow, because if the options are someone dies or it tosses the rods out trying, it's better to toss the rods out trying. I've never tested that beyond what I was told (so a tech may have witnessed a school bus derating in reality), but it seemed plausible.
This could all be different in Canada too, of course.
Anyhow... You've found the one school bus nerd in your viewership. Or at least I was in days gone by. Also, props to the guy that did the exploded animation on that thing. That took a few minutes. ;)
I'm in Rhode island and I definitely will be checking out xcallibur for my allison transmission rebuild
6th comment! Would be first, but didn’t have a built Allison transmission to get me here in time
But only 5 gears...
Its amazing they can do all of that work for that price. Alot of equipment used.
This is a bit necro but I have a bus with this trans and was just wondering if anything had to be physically changed or updated on the valve body or were the only required hard part changes for the park pawl and 4x4 housing?
Amazing behind the scenes video on this transmission just stunning work and upgrades thanks for sharing Rich @Deboss Garage
Finally hit a notification after bit on a video.. holy crap the production on thud channel is blowing my mind. Nice work, Rich!!
Can't wait to see this project finished.
So many parts. I consider myself quite mechanically minded and have fixed most things myself but the internals of a auto is still largely a mystery.
Love the logo on the trans.
Man that thing's big. I have put a 6 speed 1000 into my Humvee that doubles as a work truck and I thought that was kind of big (I usually work with small sports and rally cars for perspective). Going from the 3 speed to the 6 speed pretty much solved the whole "top speed being ~65mph if you're lucky while pinging rpms" problem and really bumped up the fuel economy. Planned on replacing the Detroit but after doing some basic upgrades to it plus the transmission swap I haven't felt any need. I don't haul or anything with it, it's just something fun to drive around that I can flush out easy and toss an engine in the little bed or something to move around. I've done a 14 hour round trip in it since the swap and it was smooth cruising the entire way with the new seats.
That’s a lot of money for something a little 1/2 ton pickup could do for 3x the mileage.
Whole trucks that, ya know, cost less than your transmission.
A 2000 and a 1000 are physically the same size.
That’s awesome, they sure know what they’re doing, cool to see the process.
I've got 880,000 miles on my 2011 Duramax with the Allison 1000.
the excitement in his eyes, like a boy receiving a new toy :))
what aftermarket electronic kit did you use to get the Allison to work , do you know who makes a standalone kit for 12 v Cummins ?
so could I bolt one straight to my 7.3? I found one from a dt444e so in theory it should work
I've got a 3116 in a medium duty TopKick that is an absolute DOG. Is it worth trying to get any power out of the motor or just swap it for a DT466 or something else in that range?
Awesome fast pace update, i love it! Thanks Rich!
Did I miss the part where lubricant was applied during assembly?
The transfer case adapter is the best part. Now it looks factory!
Amazing video Rich - thank you.
You got your trans from my neck of the woods pass by that place every day
Did you say you had to put a transfer case out of a Chevy behind the Alison?
I know this is off topic and may not be seen, but if you plan on going to Mosport (Canadian tire motor speedway) to test the Quattro i'd love to come see it.
Gotta love Ally.
How much for the stand alone controller for the transmission to work
Does Defeo bullet proof or I guess build the 4500 transmission so it can handle higher horsepower? I run a 700 horse Cat and want an Allison behind it.
Man that’s a nice unit! I would be lying 🤥 if I said I wasn’t jealous!
I’m on the fence of eventually either dropping an Allison in my 05 common rail or just rebuild the 48re...what do you think?
Rebuild that 48re... Firepunk, Muldoon’s... they can handle plenty of power with the right parts
Our vote would be on doing the Allison swap. That is pretty much all we do, if you have any swap questions, feel free to give us a shout.
9:17 Dig that grooovy music white boy
Curious how much of a diff the extra gear makes on an a1000? Is it worth the extra couple thousand or should you just put that money in the bank for gas money for the extra rpms? It’s my understanding they all have the hardware for it, just needs the valve body and software to use it?
Great video very informative as always Rich @Deboss Garage
How you get them unlock 6th gear? What year is that trans?
They did a great job filming that rebuild.
Is this like the Allison transmission on the Duramax?
Very proper, good stuff!👍
That transmission is gorgeous rich @Deboss Garage
I can’t believe how dry they put it together
All the performance shops are out by Danbury CT for some reason...
What transfer case is this? I have the 3126 engine and a 2000 trans. Thinking about trying this…. Gotta have 4x4 where I live lol.
Did you ever find out? It looks like a GM t case.
How good is the Allison transmission
When it is not running GM programming they are a darn tough transmissions.
why are they rated in HP shouldnt they be built to handle X amount of torque with HP being pretty negligible?
im sure they hold up fine with a 500hp turbo 4banger infront of it that might make 280ftlbs peak torque but take a 300HP cummins that might peak out at 1100ft lbs big difference but youd think the little gasser would be harder on it purely looking at HP not a realistic combination but shows my thinking
HP is calculated using the torque output value, at least on commercial applications. So... one 400HP diesel will make close to the same torque numbers as another 400HP diesel.
Except the little four banger won't bolt to it, and all of the engines that do operate in the same RPM range. HP is tourqe and rpm, so since the hp max is known and they all run in the same rpm range, the torqe figure is factored in even if it doesn't get a spot on the pamphlet.
Yea basically it is built to a torque spec
But they make it HP rating because that's what the consumer wants
Its easier to split the difference between makes and models when searching the Web
But I bet if you actually asked them they could tell you the torque rating of each and every component in the trans
For those interested horse power is toruque (in ft-lb) X rpm / 5252
Doesn't matter if its a deisel a petrol electric or steam engine
The same formula for everything
@@fowletm1992 i realize torque is HP times rpm/5252 but my point was the trans doesnt care about rpm it cares about torque, and as far as everyone operating in the same rpm range thats a very specific assumption.. its pretty easy to add valve springs an rev a cummins out to 4500 rpm for extra power but that does nothing for torque
@@AndrewBrowner
If you were serious about performance and talked to the builder they'd quote you per torque rateing
But for the general consumer and advertising theyre done in horsepower
Its purely advertising
Just like turbos and intercollegiate and axles
Everyrhing is rated in a round about horsepower even if its a bit irrelevant
Could prob get hp rated headlights
This truck is going to be sweet
I have a 02 24V DRW Ram with no Trans. I keep being told go with the NV5600 but buddies of mine who run shops are telling me parts for those are becoming limited. My Options just from my research are NV5600, Eaton 10 (Overkill), Eaton 8LL and just recently Ive considered the Allison Trans. Now Im stuck figuring out diff in 1000-2000-3000 Series Allison's. Any Suggestions or other Trans options. Im looking for RELIABILITY over all. It will be Towing avg 12k to 17k lbs somewhat often and I do not plan on taking it past 400ish in HP down the Road.
I should mention. Needs to be on a budget if at all possible unfortunately....
You know you made it when your name is engraved on your custom built transmission.
You pick up any of those propoint wrenches, Boss?
If you're parked on a hill you should be using the parking break also!
So transmissions arent really my think but how would u turn a 5 speed into a 6 speed with out adding hard parts ?
Pros make everything look so easy
Thats a really good price for an Allison. A 6l90 will cost you nearly as much. Its making me rethink my idea of a 6l90 behind my 6.5 when an Allison can be had for nearly the same.. What the difference between the 1000 and the 2000?
Love your working on this finally
I had never heard of defeo or xcallibur until I met them at ucc in 2017, they blew me away with their products, especially their 6pinion planetary for the Allison 1000
Need Allison for project vehicle of my own, have pump to mount on one for knuckleboom crane I have....
Eventually.
I've been looking at these transmissions for a 1000 series.
Do you need to ship the old one back?
What about reprograming?
Looks professional an high quality
Yea, no, they assembled it dry with no assembly lube or pre soaking the clutches. NOT professional.
Eccentric Smithy thought when they tested the valves it would put oil into clutches
Best OBS build ever
that was a really cool sponsor roll
I was surprised to see that they didn't presoak the frictions.
They didn’t show actually doing it but they did look wet on the way in if you look close
I came to the comments for the same reason. The first few may have been soaked but a saw alot of dry fractions going in there. My hope is after doing mesuments it came back apart and got soaked.
@@ronfrance4041 I only saw bone dry frictions going in.
it was just a dry fit for the video demo so they wouldn’t make a mess. They do soak everything. They also fill the units on the dyno and drain them to remove any break in material which many trans builders don’t have the ability to do.
great video but can we know more on the interior swap from the last video
Beautiful. Wish I could afford all these goodies
Well, it attaches to a lot of engines that use the SAE No. 3 bell housing.
I believe the Allison 1000,2000 and 2400 have 4 or 5 different bell housing options.
I'm leery when transmission ratings are given in HP instead of a torque rating.
Especially when it wants to go behind a Diesel. 🤣
Exactly. It's almost meaningless that way
Loved this one!
Beautiful video bud!
Excellent trans vid.
Gives me an idea.
I might paint my transmission if I ever have to take it off the car.
Probably blue. High temp paint.
And sand my exhaust to a mirror finish and high temp clearcoat
Looking good
Keep going I love this build!!!
Man i wish that was in my '93 crew cab dually (Chevy)
