2016 Ram 2500: complete transmission failure

Filed Aug 31, 2026 · Electrical, Transmission · SC

I am reporting a transmission safety problem with my 2016 Ram 2500 Cummins that began shortly after FCA campaign U29 was performed. Before the recall work, the transmission and original solenoid were functioning normally. I had no transmission symptoms, warning lights, or transmission codes. The dealership performed U29 and replaced the transmission solenoid May 4-6, 2026. I picked the truck up May 6 at 149,091 miles. About 79 miles later, the check-engine light came on and transmission problems began. While driving, including on the interstate, the truck would suddenly jerk, the RPMs would rise quickly, and the truck would lose speed. On several occasions, traffic behind me had to react quickly to avoid hitting me. The dealership told me the solenoid installed during the U29 repair was defective and replaced it with another solenoid. The same problems continued. The truck later developed code P0871, became undriveable, and was towed back June 1. The original transmission ultimately failed. The dealership then installed a Mopar remanufactured transmission. I picked it up June 13. Within roughly 600 miles, it developed substantially identical symptoms and failure patterns, including P0870 and P0871, limp mode, and another major transmission failure. It was towed back June 24. The dealership later found the overdrive clutch had disintegrated and metal was present in the transmission fluid. The failed remanufactured transmission is now being handled under its Mopar warranty, and the dealership is looking to install a third transmission without identifying a clear reason for the repeated failures. I am concerned the same problem could happen again and believe the U29 repair, replacement parts, or another related transmission problem should be investigated.

I have a 2016 Ram 2500 Power Wagon that i have turned into a show truck. The truck has never been off-road or in the mud, it is driven to and from the shows. Last [XXX] as i was driving to Hickory, NC for a car show on Saturday August 31st my truck instantly lost power and turned on the engine light. The transmission felt like it was stuck in second or third gear, so i pulled over and scanned the PCM to see what the DTC code and it came back as P0870. Went online to research the code and see what it had to say about it and it stated to clear the code to see if it comes back on which i didn't. The light has not returned as of yet but when the truck hits overdrive it has a high pitch squeal coming from it meaning the transmission. I brought it in to my local dealership on Wednesday September 4th to have it looked at they performed DIAG and CVI inspection to find the transmission is starting to fail internally recommend replacing the transmission. Now want me to pay out of pocket for a new transmission even though i have max care warranty on the truck when i bought it new. i don't have $6000.00 to pay for a new transmission that's on back order. If it comes down to it and i have to get my neighbor to help me get the transmission out of this truck cause I'm [XXX] then i will rebuild it my [XXX] thing myself before i pay them $6000.00.

I was driving my truck on the freeway pulling a loaded stock trailer. The truck suddenly down shifted into fourth gear and the engine RPM’s maxed out! I almost crashed the truck because the momentum of the trailer pushed the truck sideways on the freeway. I had to avoid traffic and get to the shoulder. Truck would not shift out of fourth gear and truck shifted into 4WD low also on its own. Had truck towed to dealers ship and was told a shift solenoid went out. Because of that they now have to change the torque converter and replace the transmission from the damaged it caused. It is unknown if it damaged any of the engine components at this time or any other parts of the drivetrain. Now I’m stuck paying for a transmission because Dodge didn’t put a safety backup into their system to prevent this in case of a failure. I see that I am not the first person it’s happened to by reading the power train comments for this year truck.
