2020 Ram ProMaster Powertrain & Transmission Problems

The contact owns a 2020 Ram Promaster 1500. The contact received notification of NHTSA Campaign Number: 23V301000 (POWER TRAIN). However, the dealer refused to replace the transmission. The dealer informed the contact that replacing the transmission was not included in the remedy. The contact stated that the failure of the transmission caused the front pump to not function as intended. The contact stated that on a separate occasion, the transmission failed to function as intended. The contact attempted to shift the gear lever; however, the transmission failed to engage as intended. The vehicle was taken to the dealer, and the Powertrain Control Module calibration software was updated. The contact stated that the vehicle remained at the dealer. The manufacturer was made aware of the failure but provide no assistance. The failure mileage was 95,000.

The contact owns a 2020 Ram 1500 Promaster. The contact stated that while driving at various speeds, the transmission unexpectedly downshifted. No warning lights were illuminated. The vehicle then returned to normal functionality. The local dealer was not contacted. The contact attempted a hard reset on the vehicle. The contact removed the battery cable, waited for several minutes, and then reinstated the battery cables. The contact stated that the failure persisted.

The manufacturer was made aware of the failure. The failure mileage was 64,315.

Transmission failure: Debris that caused the need for the 44A recall clogged the internal pump causing seizure. RAM service stated the need for transmission replacement, my cost.

The vehicle fails to go into gear when placed in DRIVE until the accelerator is pressed. It then shifts extremely hard into first gear and continues to shift with a hard thump into sequent gears until it reaches the higher gears. Extremely dangerous in city traffic. I managed to get the vehicle to a dealership for a warranty repair. They diagnosed the problem as a defective transmission. After five months of waiting, a new transmission was received and replaced. However, it didn't fix the problem. The dealership's fix was to order a second transmission. I'm still waiting with no ETA after eight months.

The manufacturer was made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

The transaxle downshifts whenever the accelerator pedal is released and the vehicle gains speed. This happens anytime, not when the driver wants to slow down. In the snow this has caused me to loose traction (unwanted engine breaking). There is no way to turn this off. I've spoken with other ProMaster owners and they all report the same issue. The transaxle should only offer engine breaking if the driver is depressing the brake pedal. Not whenever the vehicle accelerates. I believe this feature should only be active in "tow/haul" mode, and not be active in "Drive" mode. Even when the gear selector is in "manual mode" the unwanted downshifting still occurs. This has caused me to loose control (steering) as the vehicle is FWD on several occasions. No other vehicle I've ever driven acts this way. This has caused me to go off the road in snowy conditions.
