Wow, you are one of the few people on youtube to do this Allison swap on a 6.7 Cummins truck. I like the way Allison automatics shift in busses and trucks.
Southern Arizona I-8 to veto legislation rd South 5 miles big metal building. Sunday afternoon 12 pm Don’t be late Tough guy has to make a fake channel Let’s see your face tough guy
I thought the aisin was supposed to be a competitor? I'm new to this scene and trying to find my setup and would love to have your quick input between the two? I'm going for a tow rig/off road travels.. thank you for your time🙏 Awesome setup!!
Aisin internals aren't as beefy as Allison. With good maintenance, the Aisin are good, just not as good as Allison. Allison are medium duty trans fitted to a pickup truck
Aisin came from factory on some I think the 3500s only though but the Allison has A LOT of aftermarket upgrades and you can go a whole lot stronger with an Allison.
Austin is by no means a chump. Allison has just been doing this for a long time and their insane design durability mixed with aftermarket capabilities as well as ease of work makes them just better overall. Wouldn't complain if you gave me either one for free though. But if it's money, I'm going to the Allison
I have a 2010 dodge, I’ve love to do this, how much it cost and what was needed to match the 6.7 to that Allison. Last question is this something I could do in my garage?.
Yes you could do this in your garage. You need a good supply of tools but it’s actually not that difficult. My conversion cost over $13,000. I had mine built to survive 1000 horsepower at 56,000 pounds with 100 percent duty cycle.
Stacy, you mentioned that you broke the frame of your truck, what type of weights were you hauling and for how long? Also, did the failure have anything to do with the rear suspension modifications that you made for the air ride? Did you do any welding or or cutting in those areas? Reason I am asking is I am going to be running about 4500 pounds over weight pulling my 5th wheel camping trailer. Don't like the cost of the new trucks right now and I still like my 04 Dodge dually. I think I need to find Cad and Chassis or 3500 and look at and measure the frame rails to see what is currently on the market as a comparison. Bob
When I broke the frame I was hauling with the trailer about 36,000 pounds. Plus while doing the air ride modification I had welded to the frame on the bottom. That is exactly where the frame broke. It didn’t really break it ripped the frame kind of pealed it. It was too much weight combined with welding. The frame on those dodges is very capable.
@@stacyp4534 Thanks for the reply. Its to bad that you lost this great ride. When I had read that you had modifies the suspension with the bags and four link, I kind of thought there might have been some welding involved. I know that when I bought the 04, there was a lot of chatter about Dodge not wanting you to do anything to the hydro formed frames, in fact they didn't want you to drill any holes. I know it is not going to be the best but I think that I will be OK at about 26,000 GVW. I am going do some more research to verify that there is a TCM to work with the 04 platform so I will be able to all the functions of the truck. Have to keep the wife happy if she need to drive the truck. I am looking to have the truck function as close to original as possible. I think there is someone by the name of Jason that has the programming down. I am looking to use a SAE #3 Allison transmission bell housing along with the Cummins adapter, allowing the use of the Dodge starter on the left side of the engine. I need to start looking for some old school bus's to locate these parts. I have the wacky idea of replacing my 5.9 with a Cummins 6.7 crate engine seeing that I done need to worry about EPA requirements. It would be much cheaper than replacing the truck with a current model. Did you upgrade the transmission with billet input and output shafts? Any problem with the flexplate? I know that you were pulling a lot of HP from your engine.
Stacy, I see that you had 3.73 gears. Did you do any pulling in the mountains with the Allison and 3.73's? I am running 4.10's and talking with Dually Depot in Elkhart Indiana, they thought that was 2 much gearing and the 3.73 would be better. With the HP and Torque you had, the 3.73 would have been no problem.
@@sandipelczynski8003 I still have the truck. It’s a monster even in mountains. I fixed the frame then fish plated it. Totally rebuilt. I now mostly use an international CV-515 but the dodge will run circles around the international.
Does it keep the truck above 1500 rpm most of the time? This trans with the 6.7 would basically be the best combo to date in 3/4 ton and 1 ton pickups. I just wouldn't really want to be driving around empty at 1500-2000 rpm wasting diesel
@@stacyp4534 So it won't let you say cruise up a hill unloaded at 800 rpm like the factory transmission options will? Not trying to be nit picking, just wanting get a general idea from someone who's put miles on the setup and all.
@@xTheJmanChannel I’m not sure about that. 800 is pretty low going uphill. I only use this truck to tow so I try to keep my rpm’s at about 1800 to 2200 when cruising up hill. That’s where my turbo builds the best boost. I know a few times when unloaded it tries to lug up hills but because of my turbo setup my power band is much higher. With the correct turbo and intake combination you should be able to lug uphill. The transmission shifts down a gear at I think 1000 rpms. Mine is set there. CAC can probably program it to shift anywhere you want it to.
Engine rpm and fuel economy seem to have some contradictory data. I assumed when I regeared from 3:23 to 4:10 that my fuel economy would drop proportionally; but it did not. I changed the gears because of the constant slippage of the 68RFE (2014 Ram 2500 Cummins) and the fact that I almost always use it for towing a 9000 lb race car trailer; I bought a Jeep for daily errands because the slippage annoyed me so much. After the new gears were installed, my empty truck fuel economy went UP 4 mpg. I found the truck was much more drivable, I actually went from hating to drive it (due to the sluggish acceleration and slippage) to actually enjoying the truck. Reading some of the truck forums, there seems to be a split consensus as to whether the lower axle ratios do actually provide better economy; or looking at it the other way, do higher axle ratio swaps negatively affect fuel economy?
@@briangc1972 After a lot of thinking, research, and reading your comment on slippage, I've decided that my next truck will be a duramax with the 10 speed. I don't even want to step into fiat/Chryslers vehicles after seeing the amount of fit/finish and overall quality issues they have on top of the actual major mechanical issues they have in every area but the cummins engine itself.
You cant afford swap lol just kidding i miss my allison already I just bought a 19 limited cab and chassis. The Allison was very smooth with 500 horse tune on her.
The transmission conversion was just over $13,000 from CAC conversions. I did a bunch of other work to the truck also. With that work I was upwards of around $22,000. But that was high flow aluminum radiator and high flow intercooler. All new pipes new turbo new intake a lot of stuff.
The transmission part of the conversion is roughly $15,000. I spent $13,000 for my conversion but by the time I was done doing the engine mods I was at $22,000.
Yes, when I first put the transmission in the truck it shifted so hard I thought it was going to break a U-joint or the driveline. It shifted extremely hard. Even now every once in a while for some odd reason it’ll hit hard on a shift. Most of the time now it shifts like any other transmission. I absolutely love it. If you can afford it I highly recommend this conversion.
No I does NOT but it has 2 clutches and it shifts really smooth. I did have an issue with hard 3rd gear shifts but I kept messing with it and It learned to shift smooth
@@stacyp4534 I figured it didn't since the shifts looked quicker than most GM stock trucks. Congrats on the build, it is really cool to see true aftermarket solutions to the adorable units Chrysler calls a transmission
@@lundenherndon7000 hahahahahaha you got that right. People get kind of defensive if I talk negatively about the transmissions used in the ram trucks but my experience is that they’re junk even when built to handle loads.
@@stacyp4534 All the ones I've seen are flashed to a manual trans and use little indicators like this. Just wondering if there was a specific reason for not using the dash.
@@SteedDolan honestly I have no idea. This would be a question for CAC. I know nothing about programming on this stuff. Sorry I don’t have the correct answer on this.
@@stacyp4534 Other then the dash, does anything else not work like the OE transmission? Like the reverse sensors, reverse camera, tap shifter, tow haul, ect.

Thanks. If you decide to do one give it time to learn to shift. I absolutely love it. That’s how they should have been from the beginning
@@stacyp4534 who did your conversion ?

@@stacyp4534 what did it cost Ruffley ? A company is quoting me $12k just for parts

Several different shops. A shop in Phoenix and 2 in Vegas. Hillkiller 68 won’t last behind a deleted truck with slight tuning
@@stacyp4534 I live in Phoenix. What shops were you using? Is it an Allison 1000 or ?

What does the wiring look like is it clean looking or a rats nest
The wiring is very neatly done.
How can you tell the temperature on the transmission? I’m really interested in doing the swap on my 3500.
You can put a guage.
If we can help in any way on your conversion, feel free to give us a shout, be glad to help you out.
You cant afford swap lol just kidding i miss my allison already I just bought a 19 limited cab and chassis. The Allison was very smooth with 500 horse tune on her.
Where did you buy the stand alone controller?
CAC conversion supplied the controller. It was part of the kit. The kit comes with everything you could ever need to do the conversion.
Do you mind telling what you paid? Hey
The transmission conversion was just over $13,000 from CAC conversions. I did a bunch of other work to the truck also. With that work I was upwards of around $22,000. But that was high flow aluminum radiator and high flow intercooler. All new pipes new turbo new intake a lot of stuff.
Right on. My question was more related to the transmission. Seems like it’s worth it to me.
In my opinion it’s 100 percent worth it. I would do it again.
Can you tell a difference towing ? Like more torque or power to the wheels?
Huge difference. I have yet to find it’s limits. Between the engine power and transmission locked in it pulls hard.
Stacy P sounds good. I agree it’s the perfect auto set up.
How’s it do when you stomp on it?
Daniel Warren I try not to but if you do it will leave marks with all 4 tires
What was the price on the conversion?
The transmission part of the conversion is roughly $15,000. I spent $13,000 for my conversion but by the time I was done doing the engine mods I was at $22,000.

@@GrumblesM4 He got the adapter from us, as well as the tcm controller.
Does yours lag at all or shift too fast? I don’t think I did the learning process right.

Did you see any improvement on performance or fuel economy?
