2022 Ram 3500 Powertrain & Transmission Problems

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. This failure To issue a recall left me stuck in a dangerous situation and could have resulted in a crash.

Vehicle lost drive via the transmission when it disengaged unexpectedly. Known issue that Stellantis classifies under "Customer Satisfaction Notice" instead of a recall. There are many examples of recalls issued by other manufacturers related to loss of drive via the transmission, so why is this being treated as a notice of inconvenience versus a safety issue? Issue is being addressed via a Technical Service Bulletin where units that fail are repaired after the fact versus proactively inspected and replaced.

***1*** The emissions system on this truck (2022 Ram 3500 with 34,435 miles) has been problematic since I acquired it 5 months ago. It continually attempts to regenerate and rid itself of ash/soot buildup. If it does not successfully regenerate, it will go into a state of reduced power, also known as limp mode. The truck is available for inspection and will be at Lithia CDJR in Corpus Christi tomorrow, 07 Jan 2026. ***2*** Today specifically, the truck flashed a message EXHAUST FILTER NEARING FULL SAFELY DRIVE AT CONSISTENT SPEED TO CLEAR. I got on the highway to achieve this and avoid lights and stop/go traffic. It typically takes around 25 minutes of consistent driving for it to clear. But today, shortly after I reached highway speeds, the truck entered limp mode, displaying EXHAUST FILTER FULL REDUCED POWER SEE DEALER. This was a very alarming incident that created a bottleneck on the highway and presumably for me to nearly be rear ended as it happened at 5:35pm. I was able to safely make it off of the highway, however this incident has put the lives of all motorists on the road around me today in danger. ***3*** The truck has been inspected numerous times by the dealership. The Diesel Particulate Filter was replaced on 01 October 2025 (this was the first time the truck went into limp mode on me). The frequent regenerations continued after the DPF replacement and a sensor was replaced on 29 October 2025. Regens continue at approximately 1 per week. ***4*** This is a known issue amongst the community of RAM truck owners. It's unfortunate that many do not report it because the safety issue could easily set off a chain reaction, especially if this heavy duty truck were to be towing a heavy load as it capable of doing.

I have had the seal between the transmission and transfer case replaced 3 times due to leaking since new and after each repair within miles of each repair and all prior to the vehicle reaching 50,000 miles. The last time it was repaired at 65,000 miles they decided to replace the transmission with a new transmission - it also leaked between the transmission and transfer case within 1 day and less than 100 miles.

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

My pm sensors or particulate matter system malfunction and failed which lead to emissions issues and created my vehicle to drive in limp mode. Limp mode basically slowed downs the vehicle is slow as 5 mph as soon as this light displays at any time while driving on the highway. This put my safety in danger and the public as I transport what dot considers a type hazardous material. The sudden loss of power in the middle of the road has made vehicles around me extremely vulnerable to fatal collisions. I took my vehicle to the dealership where they confirmed this malfunction and problem with my vehicle but no recall has been issued as of yet no warning lamps appeared prior to the failure.

Transmission failure while driving not allowing to go in park after we got stopped. Truck un operable to get out of traffic.

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. Research Noah Leotta Police Officer Montgomery County Maryland. The circumstances we experienced were exactly how he lost his life. I have not received work ticket from dealership, I will follow up with documentation when requested.

While driving around 20 mph, suddenly heard a clunk, then several dashboard warning lights came on. Truck suddenly had no torque- would only move forward if the engine was revved at much more than normal amount. Nearly complete loss of ability to accelerate from a stop/low speeds. Took to an independent service center who ran the ODB codes, showing the now well-known issue of "transmission failure gears 1-4" Warning lamps include the lane sense and check engine lights, and a message on the dash that reads ACC not available, Automatic high beams not available. Prior to this, no problems with the truck at all. I am trying to arrange getting it towed to a dealership.

22 Ram 3500 Cummins diesel with Aisin transmission. Transmission output shaft seal leaking in between transmission and transfer case.

The engine stopped while driving with no warning and provided no opportunity to exit the travel lane of the road. No warning lights were illuminated on the dashboard and all gauges appeared normal leading up to the event. This event is extremely frustrating, but I am thankful that it didn't happen on the interstate as there is no telling what the outcome may have been......... Leading up to the event, I had been driving on the interstate around 70mph for about 180 miles since the last restart. I exited the interstate and made it about 3/4 miles on a secondary road and the engine died without warning and the truck came to a quick stop in the lane of travel. No abnormal sounds were observed, just a sudden unwelcome deacceleration that did not provide enough time to exit the lane of travel. It was like stepping on the brakes. I attempted to restart the truck and the starter would not crank the engine and briefly pulled enough voltage to kill all the electronics. I attempted starting it again with a jump box attached and met the same result. The computers freaking out from the low voltage during the starting attempts wouldn't allow me to put the truck in neutral to move it out of the lane of travel. A police officer called for the tow truck on rotation since I was stuck in a live travel lane. The truck was towed to the Dealer on 8/19/2024 after the service department had closed and still would not turn over when removed from the tow truck. There were no signs of any fluids leaking from the truck after the event........ The next day the Service Advisor called and advised there were only 3 codes stored related to low voltage. Truck is waiting for a tech to become available to further investigate.

My truck experienced a total transmission failure while at Highway Speed towing a 5th wheel camper on Interstate I95. This transmission failure is a known issue and has a TSB 21-002-23. A k1 clutch clip becomes dislodged and the transmission will not function. Being stranded and unable to move on a busy highway is unsafe and terrifying. Aisin Transmission and RAM are well aware of this failure however I was never notified about the potential failure nor has a recall been issued. The failure occurred instantly with no warning in a vehicle with 16,000 miles and less than 2 years old. My vehicle has been repaired and the failure was confirmed as the K1 clutch clip failure. There should be an immediate recall for this known failure to be repaired prior to being stranded on the side of the highway, 400 miles from home with my wife and kids. It's shameful RAM has ignored this problem!

While towing a camper 5 hours from home. Traveling approx 5-10 MPH in slow moving traffic the 2022 Ram 3500 HO with Aisin Transmission made a loud and sudden pop. It lost all forward power as if it went into neutral. Barely using momentum to limp the truck off the side of a busy highway during rush hour with my family on board.

The transmission wont shift gears. We were stranded at a campsite. The problem has been confirmed by Santa Rosa Ram. Inspection by RAM directly is unknown. Loud clanking noises were heard many days before the final failure.

Transmission had 2 loud clunk, while stopped, and shifting into drive, lost all forward gears. Reverse works. Truck has 17000 miles.

I was driving coming to a stop for a red light and it turns green. As I go to press on the gas my dashboard lights up with error codes stating a 4WD System error of some kind. As I go to press on the gas the truck loses power and acceleration and starts making a horrible clunking noise. I took it to the dealer because it seems like a transmission issue. This is a 2022 Ram 3500 with 9300 miles at time of failure. I would hate to see what happens if I was towing a large load to lose power all of a sudden risking my life and others around me. Based on what I have researched it seems like a K1 Snap Ring issue to the T. Waiting on the "official" diagnosis from the dealer.

On June 5th, 2024 while pulling a travel trailer on vacation, we stopped for a short break and left the truck running. When we went to get back on the highway, I put the truck in gear and nothing happened. Truck would only shift into reverse with a violent bang. Would not go forward. Unhooked my trailer and shifted into REVERSE a few times and finally got the truck to inch forward at HIGH RPM. Towed to a Ram dealer and they confirmed a snap ring failure caused the forward clutches to go out. Truck is still awaiting repairs 445 miles from home.

The dealer and manufacture have not been able to fix emissions issue. It has cause severe fuel saturation in oil and has cause severe motor damage. No one cares and they brush it off as no big deal.

When pulling onto the interstate on ramp (45 mph) the truck attempted to shift up when all transmission power failed. The engine ran fine, just no power. I was able to safely pull to the shoulder and park . s Shifting from drive to neutral to park and back to drive still did not resolve the issue. I put the truck in park and shut off the engine . The transmission fluid temp, color and level was ok. I restarted the truck and shifted to reverse with no problem then to neutral and drive. It felt that the transmission engaged and I slowly crept forward. I slowly accelerated and was able to resume speed. No subsequent loss of power has been encountered, BUT the truck now has slippage from 1st to 2nd gear and occasionally 3rd. Had I been on the interstate this has a potential for serious accident incident. This is the first time this has happened. I had bought the truck used and certified from the dealer in Pennsylvania. There is currently 28k miles on the truck. There were and still no warning or codes to indicate a problem This occurred [XXX] 2024. No dealer, tech or shop has looked at this issue.
