NHTSA Complaint #11098528 — 2017 NISSAN TITAN

LOUD RATTLE/GRIND/CHATTER FROM THE TRANSMISSION AREA THAT IS CLEARLY HEARD FROM INSIDE THE CABIN DURING UP AND DOWN SHIFTS AT RANDOM TIMES. MOST COMMONLY OCCURS WHEN THE ENGINE IS BEING USED AT HIGH RPM UP TO 40 MPH THEN THE ACCELERATOR IS RELEASED ALLOWING THE 4-5 AND 5-6 SHIFT TO OCCUR AT LIGHT LOAD. THE GRIND IS MOST NOTICEABLE ON THE 4-5 UP-SHIFT. THIS HAPPENS IN ALL DRIVING CONDITIONS, TOWING, OR UNLOADED. SOME FACTS: RATTLES IN ALMOST ANY GEAR. HEARD FROM THE FRONT OF THE TRANNY AREA. HAPPENS WHEN GOING FROM A HIGH RPM SITUATION TO A LOW RPM SITUATION. DOES IT IN BOTH REGULAR AND TOW MODES. SEEMS TO HAPPEN MORE WHEN THE TRANSMISSION IS HOT. ONLY HAPPENS WHEN DRIVING (NOT REVVING IN NEUTRAL). HAPPENS BOTH WHEN I DRIVE OR MY SPOUSE DRIVES. SEEMS TO HAPPEN WHEN THE THROTTLE IS PARTIAL OR LESS THAN HALF WAY. SOME SHIFTS ARE VERY HARD AND SOME SHIFTS ARE VERY SOFT. THE NOISE COMES AND GOES AND CAN BE VERY LOUD OR VERY QUIET. IT COINCIDES EXACTLY WHEN THE SHIFT OCCURS. THE TRANSMISSION DOES NOT APPEAR TO BE SLIPPING. THE NOISE IS ABNORMAL AS I DROVE OTHER IDENTICAL VEHICLES ON THE DEALER LOT AND COULD NOT DUPLICATE THE PROBLEM. ATTACHED IS THE ENTIRE SAGA WITH NISSAN AND AT PRESENT NISSAN HAS DECIDED TO DO NOTHING TO RESOLVE THE ISSUE. I HAVE BEEN DEALING WITH THIS ISSUE SINCE THE TRUCK WAS NEW 500 MILES.
