AFTER SEVERAL ATTEMPTS, WHILE IN REVERSE AND WITH THE ACCELERATOR PEDAL DEPRESSED, THE RPMS INCREASED, THE FRONT END JERKED, AND THE VEHICLE FINALLY REVERSED IN THE DRIVEWAY AND WAS PARKED. THE CONTACT PURCHASED TRANSMISSION FLUID, A GASKET, AND A FILTER AND TOOK THE VEHICLE TO AN INDEPENDENT MECHANIC TO REPAIR THE TRANSMISSION. DURING THE REPAIR, PROCESS METAL SHAVINGS AND CHUNKS WERE FOUND IN THE TRANSMISSION. THE VEHICLE WAS DEEMED NON-DRIVABLE AND WAS PARKED.

SPEEDOMETER CHANGED TWICE BY ANOTHER CHEVY DEALER, TRANSMISSION SLIPPING, ALL LIGHTS WENT OFF WHILE DRIVING AT NIGHT, CRUISE CONTROL WENT OFF BY ITSELF. CALLED GM CUSTOMER SERVICE AND ABOUT THE LIGHTS AND CRUISE CONTROL, ANSWER WAS TO HAVE IT CHECKED, ALSO HAD THE TRANSMISSION CHECKED BY THREE DEALERS, ONLY ONE SAID YES IT WAS SLIPPING (TRANSMISSION HAD BEEN SLIPPING SINCE I GOT THE CAR). NO PAPERWORK DUE TO COST TO HAVE IT CHECKED BY TWO DEALERS. ONE DEALER (WHERE I GOT THE CAR) NO LONGER IN BUSINESS BUT HAD THE PAPERWORK FOR THE TRANSMISSION COMPLAINT. BUT THEY TOO SAID THEY COULD NOT DUPLICATE THE PROBLEMS AND BECAUSE OF THIS THEY REFUSED TO WORK ON THE CAR.

WHEN COMING TO A ALMOST STOP AND U START TO TAKE OFF ITS LIKE THE CAR ISN'T IN GEAR THE AFTER THE RPMS GO UP IT JUMPS IN GEAR SPINNING THE TIRES. THEN IT WILL PAUSE IN BETWEEN GEARS AND MAKE A THUMP WHEN IT GOES IN GEAR FROM 0-55. GM NEEDS TO FIX ALL THESE PROBLEMS WITH THESE TRANSMISSIONS. WE ALREADY PAID FOR THE TRANSMISSIONS WHEN WE ALL BOUGHT THE CARS FROM THE DEALERS AND SOME ARE NOT EVEN GETTING HALF THE MILES I GOT BEFORE THEY HAVE PROBLEMS. I HAD CARS I'VE NEVER TOUCH THE TRANSMISSION OTHER THAN MAINTENANCE AND IT OUT LASTED THE CAR! GM NEEDS TO FIX THESE NOW. I JUST GOT THIS CAR AND HAD IT ONLY A YEAR AND TWO MONTHS.

FIRST AT BUYING MY CHEVY IMPALA IT HAD 115,000MI ON IT ALREADY BUT DESPERATELY NEEDED A CAR BEING A SINGLE MOTHER. AFTER HAVING THE CAR A LITTLE OVER A MONTH THE FUEL INJECTORS BLEW WHERE MY CAR WOULD NO LONGER START. GOT IT FIXED. NEXT I HAD TO KEEP PUTTING POWER STEERING FLUID IN (ONCE EVERY WEEK) WENT TO A MECHANIC, HE SAID MY POWER STEERING IS GOING TO EVENTUALLY GO.. NEXT 2 MONTHS AFTER THAT MY CAR CAUGHT ON FIRE THROUGH THE LIGHTER. ELECTRICAL. CALLED THE FIRE DEPT. THEY HAD TO CUT THE WIRES AND PULL THE FUSE. 2 MONTHS AFTER THAT, MY TRANSMISSION BLEW. JUST LIKE THAT. I WAS DRIVING ON THE HIGH WAY AND APPROACHED AN ACCIDENT. AFTER COMING TO A COMPLETE STOP TRIED TO PICK SPEED BACK UP AND IT WOULDN'T GO ANYMORE THAN 15 MPH. I PULLED OFF TO A REST AREA, SAT THERE FOR 30MINS. REVERSED OUT OF THE PARKING LOT, PUT IT IN DRIVE, IT WOULDN'T BUDGE... NOT TO MENTION A MONTH AFTER BUYING THE CAR. THE TURN SIGNALS,, BRAKE LIGHTS, CRUISE CONTROL, FLASHERS ALL WORKED WHEN THEY WANTED TOO AND NOT WHEN I NEEDED IT TOO. CAME CLOSE TO A FEW PEOPLE RUNNING IN THE BACK OF ME DUE TO BACK LIGHTS NOT WORKING.. AND MY TEMP, GAUGE, SPEEDOMETER AND GAS GAUGE DO NOT WORK. ID BE IN PARK WITH A FULL TANK OF GAS, IT SAYS IM GOING 80MPH AND GAS IS EMPTY.. HATE THIS CAR WITH A PASSION.. VERY DANGEROUS CAR...WOULD NEVER RECOMMEND THIS CAR TO ANYONE....

THE CAR IS SHIFTING HARD FROM 1ST TO 2ND GEAR AND EVERY ONCE IN A WHILE WHEN I SLOW DOWN AROUND A CURVE AND THEN THE CAR HAS TO SHIFT DOWN AND BACK UP RIGHT AWAY. THIS HAS BEEN GETTING WORSE AND WORSE AND FROM WHAT I HAVE BEEN READING, IT PROBABLY ISN'T THE TRANSMISSION BUT WITH THE VACUUM MODULAR OR TORQUE CONVERTER. I ALSO HAD A 2005 AND RECENTLY TRADED IT IN FOR A DIFFERENT VEHICLE, BUT IT HAD THE SAME THING WITH SHIFTING HARD BETWEEN 1ST AND 2ND.

THERE IS A LITTLE VIBRATION. WHEN I ACCELERATE AND BEGIN TO PICK UP SPEED IT HESITATES. WHEN GOING FROM 1ST INTO 2ND GEAR THE CAR SHIFTS HARD AND EVEN INTO THIRD GEAR. I TOOK THE CAR TO GET A TRANSMISSION SERVICE THINKING IT WOULD HELP, BUT IT DIDN'T. ITS STILL DOING THE SAME THING. I HAVE BEEN ASKING AROUND TO SEE WHAT THE PROBLEM COULD BE AND EVERYONE IS SAYING THAT ITS HARD TO DIAGNOSE THE PROBLEM BECAUSE IT COULD BE S NUMEROUS AMOUNT OF THINGS WRONG. MOST OF THE MECHANICS I SPOKE TO THEY TOLD ME THAT IT WOULD BE SOMEWHERE AROUND $1800 TO GET ANOTHER TRANSMISSION AND THAT MIGHT NOT EVEN FIX THE PROBLEM. I HAVE NOTICED THAT I'M NOT THE ONLY PERSON WITH THIS CAR THAT'S HAVING THIS ISSUE. I WOULD HATE TO BE SOMEWHERE AND THE CAR JUST QUIT ON ME IN THE MIDDLE OF NOWHERE. THIS CAR HAS BEEN VERY RELIABLE TO ME UP UNTIL THIS YEAR. I WOULD LOVE TO KEEP THE CAR BUT I DON'T WANT TO CONTINUE WASTING MONEY GETTING PARTS FIXED ON IT AND ITS NOT GOING TO SOLVE THE PROBLEM.
