While this is a step in the right direction, I don’t think this will resolve much. When the snap ring fails, it takes the transmission out. This is a document to help technicians identify causes of the failure and do diagnostics. There’s still no way to know if your truck has the faulty snap ring unless they can pinpoint specific sequence numbers based on build information. I still think this is ultimately going to end in a recall. It’s important to note that the TSB extends in to 2023 model year trucks so to me, that means they’re still trying to identify which trucks are effected.
Thank you for all of your work!
I was hoping to see that too. I spoke to a dealer tech that shared the TSB info. He said the complete Aisin transmission is on back order through their network with a 60+ day lead time. There are 260 currently on-order. Ram wants them to repair the broken transmissions because they’re afraid the full replacement transmissions could be just as defective as the originals. There’s a chance it could have the same incorrectly manufactured part as the original. Sounds like Ram is still trying to pinpoint the specifics of which trucks are affected.
From what I’ve heard from some folks on the inside, it’s a manufacturer change that supplied a part that is not machined properly. There’s a groove that’s not machined correctly and it’s allowing the K1 clutch snap ring to fail. Once that happens, it’s all over. Ram / Aisin are aware of the issue, but based on the TSB they released yesterday, I’d say they’re still in the process of tracking down specifics on which transmissions / trucks are affected because the TSB covers 2022-2023 and does not specify any particular VIN grouping. Even though the TSB mentions all 2022 and 2023 trucks, I really do believe it’s only affecting a certain number of trucks built during a specific timeframe during the 22 build process, more towards the mid to late timeframe.
Good info. And clearly explains why you lose most of your forward but retain reverse.
That’s great news! Do you know if they did a complete transmission swap, or repair the original one with new parts per the TSB?
Ok I’ll add that info to your line on the sheet. Hopefully the swapped one will be a good one for you.
You can add me to the list! My 10-22 built 3500 DRW failed at 2800 miles while towing an 18k fifth wheel on 12/12. Dealer (Chapman Las Vegas) had two more just like it. It’s been sitting waiting for back order trans but just got notified this week that new trans shipped out 1/17 (interesting since it shipped after TSB), supposed to arrive this week but haven’t heard any update except current promised date is 1/29. I just came across this thread and TSB and let them know, asking if there’s anyway to determine if replacement has the fix or if we should order repair kit instead. I’ll post any updates here.The tracking sheet is up and running. Please share. If you are on the list, please make sure your data is correct. If not, I can update. Also, if someone is not on there and would like to contribute I can add. Public has viewing and commenting rights only. Thanks!
