2003 Nissan Sentra Transmission Problems

Your transmission is shifting into high gears unexpectedly and won't downshift until you come to a complete stop, leaving your car struggling to accelerate or climb hills on the freeway. You may notice the engine hitting redline before the transmission engages properly, and your car may only reach 40 mph during these episodes. The problem appears to have started suddenly without any warning signs or check engine light. This likely requires transmission fluid analysis, electrical connector inspection, or transmission control module diagnostics to identify whether it's an electrical or hydraulic issue.

Your car's check engine light keeps turning on with a P0444 code (related to the evaporative emissions system), even after a shop replaced a part. The code can trigger while you're sitting still in neutral or driving short distances under 5 miles. The issue may require diagnosing the evaporative emissions system more thoroughly, including checking hoses, valves, and the fuel charcoal canister.

ON MAY 15, TRAVELING TOGETHER ON A SIDE STREET AT 30-35 MPH, MY WIFE INADVERTENTLY TAPPED THE SHIFTER. THE TRANSMISSION IMMEDIATELY WENT FROM DRIVE INTO NEUTRAL. THERE WAS NO IMMEDIATE DANGER AT THAT TIME AS THERE WAS NO CAR BEHIND ME, AND I WAS TRAVELING FAIRLY SLOWLY. I MOVED THE SHIFTER BACK INTO DRIVE AND CONTINUED HOME. THE MORE I THOUGHT ABOUT THIS EVENT, THE MORE WORRIED I BECAME. SUPPOSING I HAD BEEN TRAVELING AT 70 MPH, IN THE PASSING LANE, WITH A TRUCK BEARING DOWN ON MY REAR? IF THE CAR SUDDENLY WENT FROM DRIVE INTO NEUTRAL, IT WOULD IMMEDIATELY BEGIN A DRASTIC SLOWDOWN, AND NO BRAKE LIGHTS WOULD COME ON! BY THE TIME I GOT IT BACK INTO GEAR AND THE TRUCK DRIVER FIGURED OUT I WAS STOPPING DEAD IN FRONT OF HIM, HIS TRUCK COULD LITERALLY BE ON TOP OF MY CAR. ON MAY 19, I TOOK THE CAR IN FOR A REGULARLY SCHEDULED MAINTENANCE AT THE DEALERSHIP. PRIOR TO THAT I HELD A TEST AND FOUND THAT I COULD ALSO MOVE THE CAR FROM NEUTRAL INTO DRIVE WITHOUT DEPRESSING THE BUTTON! THE DANGER IN THIS IS OBVIOUS, ESPECIALLY FOR ANY OWNER WITH SMALL CHILDREN. I TOLD THE SERVICE ADVISOR THE ENTIRE STORY, AND MY CONCERNS WERE ADDED TO THE WORK ORDER. WHEN MY CAR WAS RETURNED, I WAS TOLD THIS IS THE WAY THE CAR IS DESIGNED. I HAVE THIS IN WRITING ON THE WORK ORDER. I WENT TO THE NISSAN WEB-SITE AND TOLD CUSTOMER SERVICE ABOUT MY PROBLEM. THEIR ANSWER WAS THEY DO NOT HAVE ACCESS TO TECHNICAL INFORMATION AND I SHOULD CALL OR VISIT YOUR LOCAL NISSAN DEALERSHIP. I ALSO HAVE THIS E-MAIL SAVED. A MANUFACTURER DESIGNS A TRANSMISSION WHICH WOULD ALLOW A LIGHT TAP ON THE SHIFTER TO RESULT IN MOVING FROM DRIVE INTO NEUTRAL AND VICE VERSA? AND THEN, WHEN CONFRONTED WITH A DANGEROUS SITUATION, SAYS, WELL, THATS THE WAY IT IS! THIS NEEDS TO BE CORRECTED BEFORE A TRAGEDY OCCURS.*AK

I OWN A 2003 NISSAN SENTRA S-ER SPEC V. WHEN I SHIFT FROM 1ST GEAR TO 2ND GEAR AT RPMS OF 2500 AND HIGHER, THE SHIFTER FEELS LIKE IT POPS OUT OF 1ST GEAR. ALSO, WHEN SHIFTING INTO 3RD GEAR YOU CAN HEAR AND FEEL A GRIND (WITH THE CLUTCH DOWN). THESE 2 PROBLEMS HAPPEN ON OCCASION, ESPECIALLY ON A COLD START. HOWEVER, I CAN ACTUALLY MAKE MY CAR GRIND GEARS BY HOLDING THE CLUTCH DOWN AND MOVING THE SHIFTER IN AND OUT OF 3RD GEAR. *JB

THE CAR MOVES WHEN IN PARKED INTERMITTENTLY. DEALER SAYS THEY CANNOT DUPLICATE X3 VEHICLE. IT WAS NEARLY INVOLVED IN AN ACCIDENT FROM ROLLING WHILE UNATTENDED. *LA

MY CAR MOVES FORWARD WHILE IN PARK. MY REAR BUMPER IS BEGINNING TO FALL OFF. TWO LOUD AND ANNOYING GRINDING NOISES IN THE FRONT DRIVER AND PASSENGER SIDE OF THE CAR. BROUGHT IT IN TO TWO NISSAN DEALERSHIPS AND ONLY ONE PROBLEM HAS BEEN FIXED SINCE THEN. *PH
