Based on all the information I have gathered, there is no way for either you, or your dealer to positively determine whether or not your truck has a flawed transmission. The defective snap ring at the root of this issue is internal, and cannot be inspected without removing and disassembling the entire transmission. I would think either Aisin or Ram, or both, would be able to identify which units are defective by their serial number, but there has been no release of that information. Not to the dealers, nor the public. Of the 84 trucks on my spreadsheet currently, 100% of them have been “fix as they fail”. Transmissions that failed prior to the release of the TSB (on 1/11/23) were full transmission replacements. Once the TSB was released, there seems to be a trend moving towards repairing the defective units rather than replacing them. I have been in communication with pretty much everyone on the sheet, and all of the failures share the same characteristics. Unfortunately there was no sign of an issue prior to the failure. They simply fail without any warning. I wish I could give you more / better information but unfortunately that’s all that has been shared / released. The spreadsheet i made is the best source for info that I know of, and demonstrates the variables associated with the failures. My 2022 3500 aisin (built 10/9/21) has a little over 25,000 miles on it currently and it is still going strong. I operate the truck daily, and just assume it’s fine, but I would be lying if I said I trust it completely. Knowing what I know, I use the truck but am fully aware that it may let me down. There are still a large number of 2022 Aisin trucks out there that are not experiencing any issues. It seems to be the luck of the draw at this point.
