Sorry my truck has ONE radiator. My truck is a 2015 and the 13 and 14 did have two radiators. I have no idea if the trans is tied to one of those radiators or not.
For fun post the pics.
I even went all tha way up to 2017. and they all show the same parts.

Shows the same thing.
Final edit: I have looked at quite a few sites now, and they all agree. The Ram diesel auto tranny uses the same two radiator setup from 2013 to 2018.
So either they are all wrong, or you have a VERY special one off truck.
The dual radiators ended sometime in 2015 models. Some early models had them and some late models did not. 2016 and newer is one radiator.
All of the sites I checked, including some Mopar sites list the Dual radiators all the way to 2018.
In fact I cannot find a single radiator part listed anywhere.
OK, I just spent some time on the Dodge Cummins forum and found this:2013 to 2015 RAM trucks have dual radiators for cooling engine. ( I may be off on year range )
They have the same main radiator as trucks before and trucks after. Example, a radiator from a 2018 truck is identical to a main radiator on a dual radiator setup on a 2015.
The difference is 2 composite Y pipes, some smaller hoses, and a small radiator mounted in front of the main one. You get more coolant and larger surface area. In theory, these trucks should be able to dissipate heat better. Yet, 2016 n up trucks returned to just one radiator. These trucks produce more power and have higher numbers. So at some point RAM decided the original Single radiator performed well enough. Or, decided to decrease parts and POF points.
I’ve read a few guys with the dual setup, remove the smaller cooler. They do this because the top Y cracks, and it’s cheaper to just bypass the smaller cooler. Again, as the main radiator is identical on trucks before and after, cooling performance is still good. I’ve also read where many say cooling as actually improved, including AC.
The reason is because the hot air off the smaller one, reduces heat transfer on the 2nd main radiator. And when parked, the heat from the smaller one radiates on to the AC cooler. Reducing AC performance when parked.Link:Cummins radiator discussion
So it appears that
12V98 may be correct in only having one radiator, but wrong about the tranny cooler, (which was/is the whole point) as all trucks from 2013 to 2018 use the same primary/Main radiator, which has a tranny cooler in it.
If one reads down further in the linked thread, some are talking about doing a modification to eliminate the radiator tranny cooler....And yes they did touch on cold weather concerns....
So I guess the thing to ask now is:
12V98, Is your truck stock? Or did you modify it as far as the tranny cooler goes?the1adman wrote:

This is one of those internet myths that just won't go away. GM and Ford DID have a joint tranny venture.... But only for the 1/2 tons. The 2500/250 and up trannys are not included.Cummins12V98 wrote:

No that didn’t happen. The 10 speed was designed and tested by GM and Ford together. They are now the same exact transmission design, and GM recently put the Allison name on theirs.

My 6 speed transmission were a huge improvement over the old 4 speeds and I was satisfied with them until the 10 speeds came out. I would really like to have a 10 speed transmissions now.
Of course, a lot of the need for more gears depends on how powerful the engine is and how much you are towing. Both of the 6 speed transmissions I tow with are being used at or over there rated capacity and the Cummins in the motorhome was detuned to 300hp to avoid compromising the Allison 1000.
My F150 with a 6 speed has plenty of gears when towing less than 6000lbs.Huntindog wrote:

I can confirm that 2013-2014s had dual radiators and 2016 - up do not.
2015s I believe switched from dual to single sometime during that year's production. ICBW on that, but Rock Auto is wrong if they show 2 rad setup for anything 2016-up.Cummins12V98 wrote:

I find these types of comments entertaining. The AISIN Medium Duty Transmission offered in the 3500, 4500 and 5500 RAM trucks simply does not break. With the straight six Cummins the 6 speeds works great. I tow much more weight than the vast majority on here at 35k combined West Coast with ZERO need for more gears.

Cummins12V98 public statement just went into the archives for future reference. :W
As you being the RV,NET RAM expert you know this to be true.
Yes I'm the expert to predict your every move. If your truck doesn't have it and the competition does then it's not needed, but when your truck finally get's it then pulling the combined load gets advertised as great.
My 98 12V and current 01 Sport both have the 4 speed auto. NOT thrilled with either as the 3-4 shift is too far apart. I had DTT rebuild the 98 and it worked well with the increased power. The 01 has better shift pattern but still not a fan of the 3-4 shift. I looked long and hard for a 2500 4X4 CUMMINS Sport LongBed with a 6 speed stick but none were to be had unless they were thrashed.
If you will be honest I am betting you are more than satisfied with your 6 speed auto.
