I really need some help locating someone who is capable of a custom transmission job. I have a 2003 ram 2500 quad cab lond box. I am trying to get Ford's new 10R140 swapped into the truck. I have not been able to find much information on doing this. Any help is greatly appreciated.

You'll likely be in for a lot of electronic headaches but well worth it once finished. How do you plan on integrating it into the driveline? Do you have all ECM/TCM for it? How much horsepower are you making and is it worth chasing a 10 speed trans?

I'm doing this because I believe it will greatly improve mileage and just let the truck run smoother overall. I have been doing everything but engine mods. I have an edge juice but that's it. I figured I will do the engine stuff last. The main focus right now is I different trans. The 48re is just old.and outdated. But no to the electronics. It's hard to find stuff for this since these transmissions are still so new.

GM has the same trans if its the ZF, from what I understand. You'll need a way to control the trans. Some guys drop in a 4R100 in the second gens for reliability, but the real question is how much are you willing to spend to increase fuel mileage and how long will it take to offset the cost? An easier solution is to re-gear the truck to a 3.55:1 or 3.42:1 which will really stretch out the gears on the 4 speed trans. $500.00 will get you a rebuild kit and another couple grand will get you a converter and input shaft. Eh nothings cheap and the return is very minimal as we all find out over time. Most of us have spent thousands on fixing problems we all created fixing other problems instead of just driving the damn things. But in support of your effort, get the parts gathered up and start a build thread, many folks will help you solve issues as you go along. Good luck.

It will cost you well over 10k by the time you are done. Is it really worth it to you?

No matter what route I go it's over 10k. The Allison and conversion kit come out to about 13k and that's not including the fact I don't have a core Allison. I wanna keep improving this one versus buying a new truck. This one should run long enough for me to be buried in it.

I highly recommend looking at this route. Regear the front and rear axle and then build the 48re to reliably handle the power goals you want to achieve. Probably about $1500 for the regear, if you can do it yourself and then even a fully built trans will only be around $8-9k. However, if you’re only going to make what you can get with a tuner then you can upgrade the trans with an input shaft, triple disc converter, and a valve body for much less, especially if you do it yourself.

I thought about doing this as well. Does anyone know if the 5R engine adapter fits the 10R140?

I'm still trying to find an adapter. If you find anything please let me know
I can make the electronics work, that's the easy part. I currently have a 2007 Ram (5.9) that i converted over to a 2019 6.7 and 68RFE. I am using the CM2450 ECM, build a bridge that allows the ECM to talk to the TIPM. So my dash and everything works.

I read different things on trans, some say its a SAE 3 bell, some say its similar to a 5R/6R. So I don't know. Just need to get your hands on one and measure it out. If its a SAE 3 bell, then it would be pretty easy to get one on the back of a Cummins.

Have you considered this route??? If I was going to 5 speed my '01 I would have zero thoughts about going this route. Matter of fact, you may have just talked me into it.

Yes you can even go to this company called CA conversions. They specialize in putting Allison's into anything. They have a lot that lets you slap any 5 or 6 speed Allison upto 2010 model trans. I can do the whole thing for about 15k for the built trans and the whole kit from CA Conversions. But why not get a ten speed if I can. And the new ones are smart transmissions so getting them to adapt over to a Cummins should be pretty simple. The hard part is the physical adapter plates for everything. I'm probably just gonna have to wait until someone one with enough money or the right friends does it first.

How long is it going to take you to re-coupe the estimated conversion costs? There are a few cheap mods that can be done to improve mpg's, ROI on those is in the 1~2 tank range.

the 48RE is a pretty good trans once built, before I yanked mine I had it dialed in and had no issues with its performance. It did have 2 rebuilds, 1st for a part failure in the trans then 2nd was for a failed heat exchanger on the block.

ATS Diesel just posted a teaser video of their Allison conversion.

Everything in the vehicle works as if the Allison came from the factory. CA Conversions is going to be hard pressed to compete with ATS. ATS also has a bell housing that bolts to the Allison. This way you don't have to use an adapter plate or grind your block down to fit the starter.

That’s slick. He talked about swapping the 68RFE/Aisin for an Allison.... so I’d assume that will only work with the newer trucks.

It will be interesting to see if their CAN bridge will work for the new 10spd. I imagine once companies are able to tune the new Allison and the CAN bridge is functional, the swap will be viable.

It can be done and it can be done fast, if you can actually find the 10 speed. I refuse to grind my block so the only option is the Ford transmission

I'm not going to try and talk you out of it as a matter of fact I applaud you sticking to your guns. How much are you willing to pay me to produce the first 10R140 swap known on here anyway?

I bet I don't give a damn, have at it bud.
You insinuated that you had the means and the methods so I was hoping for some competition. Man what a kill joy, once money is out of the equation you don't care to develop? I enjoy building and designing this stuff.

So far I think I have the only 6.7 swap that retained all the 6.7 electronics, while having a plug and play wiring harness and controller that communicates with my TIPM, ABS and dash as if the 6.7 came with my vehicle.

You can check it out here, old video and its a lot further along. But it took me the weekend to build the wiring harness and to write the code. The controller was from an old project that I repurposed. The new controller for this is way more complex.

I have the means, methods, knowledge, experience and a track record building vehicle communication bridges to make this work. ill even go as far as to say I can build the electronics faster and better then any aftermarket diesel company in the US. When I am done the 10R140 will work and report to the dash. You'll even be able to use the factory tap shifter and tow haul.
