2022 RAM 3500 Power Train Problems

On 4 different occasions when accelerating from a stop when we proceed forward slowly vehicle will rev up to 4500 RPM without any forward movement. After coasting to side of road we put vehicle in park and after a few minutes we put it in drive and it will run fine. We have not had any code lights appear or warning signs appear.

We were traveling westbound on the interstate I-10 towards Los Angeles California on Nov 13/22 near Cabazon CA in my 2022 Ram 3500, SRW, 6.7 HO with the Aisin transmission. It was rush hour stop-and-go traffic. I was traveling at a speed of approximately 35mph when a large bang came from under the vehicle. There was an immediate and complete power loss and we had to coast to the shoulder of the road and try to avoid being struck by traffic. Once on the shoulder, I had got out and checked under the vehicle. There was nothing that I could see that was wrong. There was a check engine light that went on. Using a jobber OB2 scanner, codes P0731 (Gear 1 incorrect ratio) and P0732 (Gear 2 incorrect ratio) were present. The truck was towed to the Redlands CDJR dealer for service with only 6700 miles on the odometer....

While driving the transmission went out, not being able to engage or use any forward moving gears.

The contact owns a 2022 Ram 3500. The contact stated while depressing the accelerator pedal, the vehicle made an abnormal sound. Additionally, the vehicle occasionally would not start as needed. The fault code: P0731 (Gear 1 Incorrect Ratio) was retrieved. The vehicle was towed to a dealer, where it was diagnosed with transmission failure. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 26,000.

The transmission suddenly lost all forward gears while towing 3 utv on a trailer.

The transmission spontaneously slipped out of park and went into reverse. My safety was close to critically impacted. When it began to roll on its own, I was scooped by the driver door and dragged several yards until the truck impacted another vehicle and came to a stop. I very likely could have been killed. If anyone had been behind the truck they likely could have been killed. The incident resulted in significant damage to my vehicle and the vehicle that it ran into. I have not driven the truck since the incident to reproduce. Police did come out to inspect the accident. Has not gone to dealer yet. There were no warning light, buzzers, etc. completely spontaneous. Note: the vehicle was running when this happened. When I was able to get back in truck the stalk was still in park position

Diesel Particulate Filter (DPF) Sensor never installed, digital gauge has never read anything but 0%. This can cause issues with regeneration of the DPF that will result in Limp mode.

After vehicle is in reverse and you press the brake. When you move the shifter to park and then release your foot from the brake, the truck moves backwards about 5 inches. It acts like its still in reverse.

My vehicle came with 4X4 gear box shift on the floor. I could not get it to move into neutral or 4 low gear. I hardly drove in so it was no big deal so one day I pulled up the boot around the shift and there was a screw blocking the forward movement. It was the same screw that mount the plastic around the shift, after removing it I was able to get all the gears. The danger in that screw could have put me at risk by locking me into a gear and only staying there. The only reason I discovered this was I changed out my vinyl for carpet.
