NHTSA Complaint #11331910 — 2019 RAM 3500

I HAVE A 2019 RAM 3500 TRUCK WITH THE HIGH OUTPUT 400HP ENGINE AND THE 'HEAVY DUTY' AISIN TRANSMISSION. I AM HAVING PROBLEMS WITH THE TRANSMISSION. WHILE DRIVING IN MOUNTAINOUS TERRAIN AT SLOW SPEED (5 TO 10 MPH) THE TRANSMISSION SEEMS TO SHIFT INTO NEUTRAL, ENGINE WILL REV UP TO 2000 TO 2500 RPM FOR A FEW SECONDS AND THEN SLAM INTO GEAR, CREATING A SAFETY HAZARD. THIS HAPPENS ON A CONTINUAL BASIS. A FEW TIMES, I HAVE STOPPED AT AN INTERSECTION ON A HILL, WHEN ATTEMPTING TO TAKE OFF AND TURN INTO TRAFFIC, THE TRUCK WILL GET PARTIALLY INTO THE ROAD WHEN THE TRANSMISSION SEEMS TO SHIFT INTO NEUTRAL, SLOWS DOWN WHILE THE ENGINE REVS TO 2000 TO 2500 RPM (WHILE TRAFFIC KEEPS COMING AT YOU) AND FINALLY SLAMS INTO GEAR AND STARTS MOVING AGAIN. THE NATURE OF THE ISSUE IS CREATING A LIFE THREATENING SITUATION. WHEN YOU ARE ON A HILL AND STOP, UPON REMOVING YOUR FOOT FROM THE BRAKE TO RESUME TRAVEL UP THE HILL, THE TRUCK WILL ROLL BACKWARDS, AFTER ROLLING A SHORT DISTANCE THE TRANSMISSION WILL SLAM INTO GEAR CAUSING THE ENGINE TO STALL. AS THE ENGINE DIES, THERE IS A COMPLETE LOSS OF BRAKING AND STEERING, LEADING TO MORE LIFE THREATENING SITUATIONS; AS YOU ARE ROLLING BACKWARDS WITH LITTLE TO NO BRAKES OR STEERING. MY AREA HAS A LOT OF STEEP GRADES THAT WE HAVE TO DRIVE ON A REGULAR BASIS. I HAVE TAKEN THE LEMON TO THE DEALER FOR REPAIR MANY TIMES. MY INITIAL COMPLAINT AND DEALER VISIT WAS AT APPROXIMATELY 3,500 MILES. THERE HAVE BEEN MULTIPLE FIRMWARE UPDATES , WITH NO CHANGE IN THE BEHAVIOR. ANOTHER ATTEMPT WAS CHANGING THE TRANSMISSION INTERNALS, NO CHANGE IN THE BEHAVIOR. ANOTHER TRIP INVOLVED ADDING A RECORDER TO LOG THE BEHAVIOR TO SEND TO MANUFACTURER.. THE LAST TIME, I WAS TOLD THERE IS NOTHING ELSE TO BE DONE. A CASE HAS BEEN OPENED WITH RAM, WHICH HAS RESPONDED IT IS OPERATING WITHIN THE DESIGN LIMITS AND THEY WILL NOT DO ANYTHING ELSE.
