2022 Premature Aisin Failures

Well I finally got a dry spot and a chance to crawl around under my truck and grab some pics of the new tranny. I don’t have pics of my old one, because at the time I didn’t know it would be getting replaced. The blue serial number plate on the driver side and the black plate on the bottom of the transmission are easy enough to snap with my phone. However the passenger side was so tight that I either couldn’t get my phone up there, or it wouldn’t focus. So I grabbed my bore scope. Even then I could only get skewed pics. If one of these turns out to be useful I can get under there with a mirror or something and try again.
I’m case anyone is wondering this is a 2022 mega 3500 HO. I have 6500 miles on the clock. Transmission was replaced at 5940.

1- the TSB states that 5th and Rev gears will function when the failure occurs.
2- in case of a failure while on a busy hwy, how would we get the tranny to engage 5th gear so we can limp off to the side of the road?
3- has anyone reported a failure with a 2WD Aisin?

Photo bellow shows the p/n sticker on mine, 68498559AA does not come up as a good number.
Anybody know if the Aisin trans is the same for both 2WD and 4WD (minus the xfer case of course)?

Mine wouldn’t pull its self in 5th it just slipped, thankfully I have 4 wheel drive and shifted to low and was able to get off hwy , but 5/6 finally gave up .

I had reverse but it slammed hard to engage .

Ram has released a new trans for mine , dealer estimates having me on the road by Feb 16th .

5th gear may function, but after speaking with 80+ owners who have experienced this failure, you may or may not have 5th gear. It depends on when the snap ring fails, and how much damage it causes when the snap ring lets loose. If you do have 5th gear functional, you will have very little power available and your travel speed will be severely limited also. You`re basically slipping the transmission continuously at that point but if it is necessary in order to get you out of danger, or remove yourself from a bad situation, you have to do whatever you need to do. I would assume, the transmission will default to 5th and it will engage after you apply RPM to the engine. I have not personally experienced this, so I`m only speculating, however most of the people I've talked to said they increased the throttle and it eventually shifted into 5th and began moving forward. This shift tends to be extremely aggressive. Hopefully those who have gone through this will comment and describe what it felt like. I have not been keeping track of 2WD vs 4WD aisin failures as the transmission is the same. The TSB also does not designate this, so that makes me think the issue is not specific to which configuration. If it is a diesel with the AS69RC, or a gas with the AS66RC, the transmission is susceptible for this issue. Ram did not specify which VIN numbers are at risk, so it is unknown as to which trucks have the flaw.

You are correct , I had to increase throttle to get 5th gear and when it engaged, it hit super hard , I was pulling a uhaul car trailer with a 2 door Jeep (5500# total) and 5th just slipped no power to move, I went to low 4x4 and throttled up and 5th hit crazy hard and stayed engaged as long as I two pedaled it , keeping RPM’s up , I was limited to 32 mph but thankfully it got me to safety , 5/6 finally gave up ( could smell clutches burning) , I had reverse but it hit crazy hard .

That would track with most of the failures that were reported to me. When the truck is driven in this manner, it most definitely causes more damage to the transmission, as well as all of the accompanying components (lines, thermal bypass valve, and the transmission cooler assembly). When that snap ring lets go there are a bunch of parts within the assembly that are no longer held in their respective position so there's a higher degree of risk for carnage. Also, in order to get 5th moving, there`s a lot of slipping and heat build up so that makes it worse. Of all the failures I`ve talked to, the ones that were forced to continue to drive or move the truck resulted in complete transmission replacement as well as the lines and cooler assembly. For the most part, the ones that failed and were not driven further resulted in less internal damage. Either way, you have to do whatever is necessary to keep yourself safe.

At this point, it seems like the likelihood of a total transmission replacement is getting slimmer. Once the TSB for this issue was released (1/11/23) it would seem the preferred method to fix the issue is ordering the parts listed in the TSB, often referred to as the "TSB parts kit", and then waiting for those parts. ETA's for some of the parts within the kit are getting longer, as I am sure there are more and more being ordered. One owner told me he was quoted "mid March to early April" of this year. These failures are happening more frequently and at the same time, 2023 production is in full swing. I am sure there is some level of parts supply and logistics issues since both the 2022 and 2023 trucks share the same drivetrain components. I am trying to keep my tracking sheet updated and accurate as much as possible. If any of you are on the sheet, please do your best to keep me informed of your current situation, as this information is proving invaluable to others also going through the failure and repair process. THANKS!

I have a 2022 4500 4x4 cab chassis. The first week of work it blew the tranny ant 5,000 its been at the dealer for basically 30 days. Stellantis gives weekly updates and they updates consist of (there is no update). Bought the truck November for hot shot. Theres 6 more with the same problem at university dodge. It goes in reverese but no forward.

That sounds like the K1 snap ring failure. I’d like to include you on the tracking sheet if you would be willing to participate. You would be the 84th truck on there. Let me know!

No problem, i just don’t know when it was built.

Ok thanks I’ll add you.

If you’re not sure of the build date, you can send it to me whenever you have a chance to look at it. It’ll be on the sticker on the drivers door as “date of manufacture (built)” and it’ll be a two digit month / two digit year like “11/22”

This is everything I need to have complete info on your slot:

Date you ordered it
Date of manufacture
Date purchased
Miles at the time of failure
Towing when it failed?
Lost forward gears?
Reverse still worked?
Date transmission failed ?

I will get that on the tracking sheet in a few minutes, when I’m sitting at my desk. Have you had a chance to review the sheet? It is open to public view. The link is at the beginning of this thread. I appreciate your input. Also, if you need any specific info or have questions please feel free to message me directly, or post here.
 
I did take a brief look at it, i just hope they can figure this out so that we can get back to work

Ok great!

They’re working on it, but parts supply seems to be the hold-up. You’re one of several hotshot haulers on my list. At least it would seem your dealer is well aware of these failures if they have that many trucks on the lot. Some of the people I’ve talked to are the first ones their dealers have had to deal with.
 
@M2 transport llc you are on the sheet. Reference line #91 when viewing. Please keep me updated as you find out more and go through the process. I’m happy to answer any questions you may have, and can share whatever accumulated knowledge / info I have. Also, did your dealer mention wether they are waiting for a complete transmission assembly, or are they waiting for parts to repair your original transmission?

Yes SIr I appreciate it, thank you. Yes they’re waiting for a complete transmission
