While travelling in Southern California, I came to a stop to enter I8 on ramp. When I tried to start down the on ramp the truck didn’t want to move and a check engine light came on. The truck went into limp mode so would travel slowly along. I called Mango Auto who could diagnose it the following morning. I did not make it to the shop before the transmission failed completely and the truck wouldn’t move leaving me in traffic in a dangerous spot. Eventually I was towed to the shop in Yuma AZ. They diagnosed it as a complete transmission failure requiring a $10,000 replacement. FCA has issued an extended warranty, but my mileage is 16700 miles over. FCA has a technical bulletin on the issue with the Austin transmission, but has not but should have issued a recall.

While driving on interstate leaving a construction zone started to accelerate to maybe 40mph and heard/felt a hard clang and lost all forward motion costed to side of interstate. Looked underneath truck, nothing visible broken or leaking. Restarted truck tried to move forward with no luck. Reverse worked, put back in drive loud noise again stomped on the accelerator and started moving forward very slow and difficult. Made it to an exit to look at things in a safer location than the busy interstate. Figured out that I had reverse and 5th gear so it was very hard/ slow to get moving. Check engine light on, gear ration incorrect, code P0731, Tran sensor failure, no 4x4 Transmission failure 1-4 gears not working

The transmission in my vehicle failed suddenly on May 31, 2025, entering “limp mode” and losing the ability to shift properly. The vehicle became immobile and was towed to the dealership. Initial diagnostics revealed difficulty shifting between 3rd and 4th gears. Service technicians attempted repair in June based on RAM TSB MC-10231775, which indicated snap ring failure in the Aisin transmission. Repairs prescribed in TSB were attempted but unsuccessful, as the vehicle still could not shift into 4th gear. Additional parts were ordered, and another repair was unsuccessfully attempted in late June. Ram has shipped a new transmission which we are waiting on the dealership to install.

Transmission failed in heavy interstate traffic while towing 35 ft 15,000 lbs RV. My RAM 3500 only has 19,000 miles and is still under new vehicle warranty. The event: While travelling on Washington DC beltway in lane 3 of 4 without warning my transmission starting slipping. No abnormal noise, no dash lamps warning of an issue. As I pressed on accelerator my speed continued to decrease. I quickly signaled to right lane in an attempt to get off the road. I was slowing at a rate I was concerned I may be stopped on highway with vehicles traveling 55 mph approaching. I did make the shoulder in between an exit and entrance ramp with barely enough room for a tow truck to be in front. I had 3 ft on my left with 55mph traffic passing constantly. The vehicle was towed to a local RAM dealer as my wife and I waited on the highway with RV for second tow service. This all could have been avoided. Why was a TSB or recall already in place? RAM has many transmission failures on the 2022 Aisin transmission noted on RAM truck forums. I had read about it but considered myself lucky as I was almost 2 years driving truck without any problems. My safety, my wife and tow truck drivers safety were put at considerable risk due to Stellantis not alerting RAM dealers of a potential transmission failure.

I have not received work ticket from dealership, I will follow up with documentation when requested.
