“TL* THE CONTACT OWNS A 2005 CHEVROLET IMPALA. WHILE DRIVING UNKNOWN SPEEDS, THE TRANSMISSION WOULD NOT SHIFT INTO GEAR. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC. THE LOCAL DEALER WAS NOT CONTACTED. THE MANUFACTURER WAS NOT NOTIFIED OF THE ISSUE. THE FAILURE MILEAGE WAS 196,000.”

“FROM A STOPPED POSITION, TRYING TO TAKE OFF CAR ACTS AS IF I'M NEUTRAL AND THEN WILL SUDDENLY JERK INTO GEAR. THE AUTOMATIC HEAR SHIFTS ARE ROUGH AND DELAYED. THERE'S VERY LITTLE POWER OR STRUGGLE TO REGISTER WHEN APPLYING GAS. WHEN ON FWY ESPECIALLY WHEN IN SLOW MOVING TRAFFIC THERE IS A LOT OF PROBLEMS WITH THE TRANSMISSION AND SLIPPING, ROUGH GEAR SHIFTS BOTH UP AND DOWN. THEN THE SCARY PART IS WHEN DRIVING WITH MY 2 LITTLE GIRLS AND IN REGULAR OR HEAVY TRAFFIC AND MAKING TURNS, ESPECIALLY LEFT, I HAVE HAD THE CAR FREEZE UP ON ME IN THE MIDDLE OF INTERSECTIONS. WHEN I TRY AND ACCELERATE I'M STUCK AS IF I'M NEUTRAL AND HEAR THE ENGINE REVVING AND FINALLY WILL VIOLENTLY LIKE POP INTO GEAR. IT'S MADE ME HAVE A LOT OF SAFETY ISSUES FOR MYSELF AND CHILDREN. IT'S VERY FRUSTRATING AND PROBLEMATIC. WITH ALL THESE THINGS HAPPENING THE TRANSMISSION NOR CHECK ENGINE LIGHT HAS APPEARED, THEREFORE MAKING IT TREMENDOUSLY DIFFICULT NEAR IMPOSSIBLE FOR ME TO HAVE IT PROPERLY DIAGNOSED USING SCANNER AND COMPUTER READER. EVERY REPAIR SHOP HAS GIVEN DIFFERENT "FINDINGS" AFTER ONLY A DRIVE AROUND THE BLOCK. IT'S A NIGHTMARE.”
