2022 RAM 3500 HO Cummings Aisin transmission trouble.

[sawgunsmith]

My truck left my wife set 600 plus miles away with a P0731 code.
My truck is a 2022 RAM 3500 MEGA cab Longhorn with HO Cummings and Aisin transmission. It has less than 6600 miles on it and has never been hooked to a trailer.
We had MOPAR Roadside Assistance tow it to RAM Country Fort Stockton which is a very small town in south Texas. The service manager there tells me that they have a technical service bulletin that says they are to find and replace damaged parts and that replacing the transmission is not authorized.
My position is that we bought this truck to be our retirement vehicle. Our traveling vehicle and we planned to put many many miles on it. Now we have a new truck with a transmission that has debris run through it and probably the transfer case and no matter what they do they will never get all that out and I and more importantly she will never trust the truck to be reliable again.
I have opened a complaint with Chrysler over the roadside assistance frustrations, the fact that the warranty only pays $35.00 a day for a rental vehicle and a vehicle that my wife can get her camping gear into to come home with cost us $85.00 a day and we are stuck for the difference, and my wanting the transmission replaced not repaired on such a low mile truck.
My fear is that the transmission has debris run through it and no amount of flushing and filtering will prevent some of the debris from remaining and causing damage or premature wear.
Also, now that I think about it, I'm certain that the transmission and the transfer case are married and share the same fluid. So now I'm worried that even if I get a new transmission there will be debris in the transfer case to deal with.
Can you help alleviate any of my concerns please?

Tough deal. I'd feel the same as you. Maybe ask for an extended warranty on it?

 

[sawgunsmith]

Oh, I plan on it.

It could be a simple sensor so before you get too wound up you should wait for the diagnosis. It could be a simple fix....

And the transfer case is completely separate, there is no shared fluid. 2 different parts that are connected externally.

I believe the warranty states FCA will repair or replace defective parts at THEIR discretion not the vehicle owners. While having issues with a relatively new vehicle are never fun, it seems FCA is living up to the terms of the warranty. Any repairs would be warranted for the remainder of the warranty terms. We see posts like this fairly often. Someone is not happy with their truck and comes here to complain, vent, etc then they are never heard from again.

There is an issue with these that cause them to fail at a very early mileage interval, and it's unique to that year and a limited number of units. When they first discovered it, they were installing new units, probably because they needed the broken ones to determine the COF and devise a plan to correct. If you can get it back to the dealer where you bought it, they would probably be more help. Otherwise, I'd open a ticket with @RamCares and let them help guide that dealer through the correct process. It sucks...But that trans is a bullet proof unit and has a simple manufacturing defect that is causing major failures. Once corrected, it'll be fine for a long time.

They are having a big issue with a manufacturing problem at Aisin. The K1 snap ring can fail, and you lose gears 1-4. It is not clear if it is the snap ring itself, or a machining issue with the groove it resides in. There is a member on CF and HD Rams who has been tracking these failures, and compiling information. There are LOTS of trucks out of commission with this. They were initially swapping transmissions, but there have been several documented failures of replacement transmissions. Ram does not seem to have, or at least admit to, a handle on a build date or serial number range for this issue, and they are being treated on a Fix-As-Fail basis. The current fix, per TSB, is to replace the K1 clutch drum assembly.

BTW, if you quit driving the truck as soon as it failed, current thinking is it is unlikely to have collateral damage. Those that tried low range, and/or flooring it to force it to move to get off a highway/out of danger seem to be the ones that did more significant damage.

You may consider reporting this to NHTSA to help spur a recall, instead of this drip-drip approach. For all the failures that have been documented, only a handful of folks have bothered to report this potentially dangerous situation.

This looks exactly like the list that is being compiled by mbarber84 on Cummins Forum..
