K1 snap ring failure

- Weymouth, MA, USA

Truck has 6500 miles, went to put it in reverse from drive in busy intersection and transmission started to slip. Truck ultimately wouldn't drive at all. Started throwing codes (P0731-00 in particular) and found out that it needs a new K1 clutch snap ring repair. There are more than 300 people with this issue, this has not only happened with me from my research on forums about this code being thrown. This is a 2022 with 6500 miles, there are too low of miles on this truck for it to be having a problem like this!

I drive a RAM 5500, 20' Jerrdan Flatbed Tow truck. We had just purchased this truck about a week and a half prior to the transmission failure. We had 2500 miles on it, and were towing two vehicles behind. We pulled off of the highway, and then felt an extremely hard clunk underneath the truck to which the rear tires locked up, and stopped us in the middle of the road. Once we were stopped, the truck began to clunk louder so hard it would shake the entire truck. Then a CEL appeared, for PO731 and P0734, the truck in drive would only rev and not move. Reverse did work however. But we could not reverse anywhere as we were in the middle of the highway. We had to get a tow truck which took 4 hours because nobody wanted to tow us due to the situation. We almost got hit so many times, it was so dangerous and scary for me and my passenger, as we thought we were going to crash when the rear wheels locked up. This issue needs to be taken much more seriously and looked into becoming a recall. Somebody on the highway could get KILLED!

Were were driving in stop and go traffic outside Durham, NC on I 147/885. After being stopped for a few seconds I depressed the accelerator to move forward. There was a bang and I thought some one had hit me from behind. Then I noticed the engine light on the dash and the truck would not move forward. I was able to get the shifter in park. All temps and pressures on the dash were normal including the transmission. There was no fluid leaking from under the truck. We were in lane three of the highway and cars, trucks, and tractor trailers were passing us on the shoulder and the left lane. I tried using the in vehicle SOS button but the guy on the other end only referred me to call a different number. That number I sat on the line for over 20min while sitting in traffic unable to move with vehicles passing me on the left and right. finally a deputy showed up and was able to control the traffic. 3 hours later it was finally towed to Hendrick Dodge in Cary, NC. Currently waiting on it to be evaluated by the dealer.

- King George, VA, USA

Description: The Aisin transmission in my new Ram 2022 5500 unexpectedly failed in the middle of the highway, despite the vehicle having only 5,000 miles on it. This sudden breakdown posed a significant safety risk to me and other drivers on the road. Unfortunately, the truck is currently at Johnson's Auto Center in Denver, but they are unable to provide an estimated time for inspecting the transmission. It appears probable that a new transmission will need to be ordered to resolve the issue. Regrettably, I do not have any further details or insights regarding the incident and its cause at this time.

Many owners have reported sudden loss of power and control resulting from explosive transmission failure causing a major public safety issue. RAM has not provided details on which vehicles are affected. The TSB states if the customer experiences such symptoms to contact dealer if still alive. This lack of information has resulted in many customers simply parking their vehicles and waiting until FCA issues more details on which transmission serial numbers are impacted. Owners have also joined various forums and crowd sourcing information (SEE ATTACHED EXECEL SHEET) to identify factors such as build dates, transmission serial numbers and conditions in which the failure happened. I am requesting the NHTSA to conduct an investigation and require FCA to provide more details regarding impacted vehicles rather than taking a if-it-fails-call-us approach. Furthermore, FCA is not reimbursing owners for towing expenses related to the load. In some cases the truck towing is covered but not in other cases if the towing cost is deemed too high. This has resulted in some owners paying over $5000 for towing expenses and waiting for repayment. In some cases the TSB repair has resulted in additional failures causing the vehicles to be out of services for multiple months and additional safety to the operators and other motor vehicles that share the road with these RAM vehicles.

The transmission failed after less than 500 miles. I stopped at a red light at the end of an exit ramp, and when the light turned green, the truck would not move, either in forward or reverse. I was in the middle lane of a 3 lane exit ramp, and cars were passing me on each side. There were no symptoms or warnings prior to the total failure. The truck had to be towed to a dealer, where they confirmed that the transmission had failed.

On the evening of 1/06/2022 I was traveling in heavy traffic going east on I-70 approaching mile marker 234 coming down a large mountain grade when i realized my transmission disengage. I was able to exit interstate and come to a stop I checked and found had no forward gears in transmission only had reverse gear. When I had secured a towing company ( which ram could not secure ) towing guy informed me that he has towed 2 to 3 of these vehicles every week for past six months with same issues. I very much feel this is a big safety issue especially when your descending down a large mountain grade the transmission may not give you the gears to safely handle the mountain grade your traveling on, causing a catastrophic accident.
