2023 Ram 2500 Powertrain & Transmission Problems

I own a 2023 Ram 2500 equipped with the 6.7L Cummins diesel and 68RFE automatic transmission. The vehicle has experienced ongoing transmission malfunction issues including extremely harsh shifting, intermittent RPM flare during gear changes, delayed engagement, and sudden lurching during acceleration and deceleration. The issue occurs most commonly during low-speed acceleration and normal driving conditions. The transmission will sometimes flare RPM between gears and then slam into the next gear. At other times the vehicle will lurch forward unexpectedly around approximately 35–45 mph. The behavior is inconsistent and unpredictable. Some drives appear normal while others produce severe shifting events. This condition creates a safety concern because the vehicle can surge or jerk unexpectedly during normal driving and while towing. I regularly tow a small enclosed trailer and these sudden shift events create instability and loss of smooth power delivery. The vehicle has been inspected multiple times by an authorized Ram dealership. The dealer has attempted repairs including transmission diagnostics and valve body replacement. The condition has continued despite repair attempts. The vehicle has also remained out of service at the dealership for extended periods of time while the manufacturer attempts to diagnose the issue. No warning lights consistently appear prior to the failure. The symptoms occur intermittently after the vehicle reaches operating temperature and sometimes after driving several miles. This issue has been confirmed by the dealership and the manufacturer has been involved in the case. The vehicle remains unrepaired after multiple attempts. Because this is a heavy-duty truck that frequently tows loads, the sudden harsh shifting and unpredictable transmission behavior creates a potential safety risk to the driver and surrounding traffic.

There appears to be leaking from the dipstick tube. Transmission lurches when accelerating and decelerating. Eddies Repair in Pagosa Springs Colorado looked at the vehicle and suggested there may be a recall on this issue. When looking up the vin my vehicle is not included in recall ZA3. I purchased this truck in March 2025 and it has been an issue from then.

Transmission just started shifting very hard causing the truck to shake. Truck was fine last week, mileage is 9600. Have notified the dealer, they said to bring it it in. There is no warning lights or alerts

My 2023 ram 2500 with 12,000 miles dose not always accelerate the way it should has been doing this once in awhile since new but has got more frequent. You can push the accelerator all the way down and truck does not take off. Makes it very dangerous when pulling out into traffic. Also the truck sometimes shifts super hard or wont shift at all. I'm dropping the truck off tonight to get checked out. There has been no warning lights yet. When I first called the dealer they told me it was a new truck and needs time to break in. Now its getting worse.
