NHTSA Complaint #11048585 — 2017 NISSAN ARMADA

WHILE DRIVING, THE TRANSMISSION HUNTS AND SHIFTS VERY EARLY, CRIPPLING ACCELERATION. AT NORMAL HIGHWAY SPEEDS, SIGNIFICANT DEPRESSION OF THE ACCELERATOR IS REQUIRED TO EFFECT A DOWNSHIFT. THIS PRESENTS A SAFETY HAZARD WHEN ACCELERATION IS REQUIRED FOR MANEUVERING. WHEN THE VEHICLE DOES SHIFT INTO THE NEXT GEAR, SIGNIFICANT OSCILLATIONS OCCUR UNTIL THE TRANSMISSION SETTLES ON A POINT. ALSO, AT HIGHWAY SPEED, THE ENGINE RPM CONTINUOUSLY 'FLUTTERS' UNDER CONSTANT ACCELERATOR POSITION AND NO CHANGE IN ENGINE LOAD (FLAT STRAIGHT ROAD). I HAVE ALSO NOTICED THAT WHEN I SLIGHTLY DEPRESS THE ACCCELERATOR TO MAINTAIN SPEED, THE TRANSMISSION RESPONDS BY FURTHER REDUCING ENGINE RPM AGAIN HAMPERING ACCELERATION (EXACTLY OPPOSITE OF ANY OTHER AUTOMATIC VEHICLE I HAVE DRIVEN). THIS TRANSMISSION OPERATES AS IF IT HAS AIR IN THE HYDRAULICS. I HAVE HAD THE LATEST TSB INSTALLED FOR THE ECM AND TCM (REVISION E). NISSAN DOES NOT APPEAR TO BE CAPABLE OF FIXING THIS SAFETY ISSUE.
