THE SHIFT GEAR HAS BECOME STUCK IN PARK TWICE. THE SHIFTER WILL NOT MOVE. I HAD TO HAVE IT TOWED TO THE MECHANIC TWICE IN ORDER FOR THE VEHICLE TO BECOME OPERABLE AGAIN. THE SHOP REPLACED SOME WIRING AND MECHANICS INSIDE THE SHIFT AREA. SINCE THEY HAVE REPLACED IT TWICE, ALONG WITH THE ORIGINAL PARTS, I AM ON THE THIRD ROUND. *TR

STARTED HAVING TROUBLE WITH MY TRANSMISSION A WHILE BACK. IF I WAS AT A STOP AND TRIED TO ACCELERATE IT WAS SLOWLY TAKE OF THEN ALL OF SUDDEN SLAM INTO THE RIGHT GEAR THEN TAKE OFF. IT ALSO HAPPENED EVEN IF I DIDNT COME TO A COMPLETE STOP AND TRIED TO GO AGAIN. MY CHECK ENGINE LIGHT CAME ON AFTER ABOUT A MONTH OF THIS HAPPENING. I HAD IT CHECKED. IT WAS A SHIFT SOLENOID. SINCE I WAS STILL UNDER WARRANTY I HAD IT REPLACED. IT WAS FINE TILL ABOUT A TWO WEEKS AGO 08/20/2013. NOW MY TRANSMISSION IS DOING THE SAME THING AGAIN.

OCCASIONALLY, WHEN STARTING FROM A STOPPED POSITION THE ENGINE WILL REV UP AND THEN THE TRANSMISSION WILL KICK IN TO GEAR. OCCASIONALLY IT SLIPS ON HILLS ALSO. WE GENERALLY DO NOT HAVE TO MERGE INTO HIGH SPEED TRAFFIC BUT IF THE TRANSMISSION SLIPPED AT THAT TIME THERE COULD BE SERIOUS CONSEQUENCES. THE DEALER HAS BEEN UNABLE TO FIX THE PROBLEM AFTER FIVE VISITS, AND APPARENTLY WILL NOT DO ANYTHING UNTIL THEY THEMSELVES EXPERIENCE THE TRANSMISSION SLIP. *TR

2007 IMPALA SS. TRANSMISSION HESITATION OCCURS WHEN GOING AROUND 45-60 MPH. CAR SEMI-ENGAGES SHIFTING, BUT THEN BACKS OUT, GIVING A CHUGGING SENSATION WHILE DRIVING IN THAT SPEED RANGE. HIGHER SPEEDS ABOVE 60 PRODUCES AN INCREDIBLE SCREECH/WHINE NOISE. CURRENTLY IN SHOP FOR TRANSMISSION DIAGNOSTICS. AT 74,000 MILES CLUTCH WAS REPLACED DUE TO IT BEING CRACKED IN HALF. GM HAS EITHER MAD POOR TRANSMISSION ENGINEERING, USING SHOTTY PARTS, OR THIS TRANSMISSION IS OVERLY UNDERRATED FOR THE POWER OF THE ENGINE. *TR

WHEN I PUT MY CAR IN PARK I CANNOT GET THE KEY TO DISENGAGE FROM THE IGNITION SO THAT I AM ABLE TO TAKE THE KEY OUT. I HAVE TRIED JIGGLING THE GEAR SHIFT ETC AND IT WILL NOT COME OUT REGARDLESS OF WHAT I TRY. *TR

CAR BUCKS WHEN GOING FROM 0 MPH. BROUGHT CAR INTO DEALER SEVERAL TIMES THEY CHECKED IT OUT. THEY DIDN'T FIND A PROBLEM BUT CAR STILL BUCKS. SPOKE TO OTHER OWNERS, THEY HAVE SAME PROBLEM. NO RESPONSE FROM GENERAL MOTORS THAT THE PROBLEM EXISTS. PROBLEM STARTED AT @30000 MILES. CAR HAS 68000 MILES NOW.

TL* THE CONTACT OWNS A 2007 CHEVROLET IMPALA. THE CONTACT STATED THAT WHILE DRIVING 5 MPH, THE VEHICLE EXHIBITED A LOUD, ABNORMAL NOISE AS IT ABNORMALLY ACCELERATED. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC FOR DIAGNOSIS AND THE CONTACT WAS INFORMED THAT THE TRANSMISSION WOULD NEED TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOTIFIED BUT OFFERED NO ASSISTANCE. THE FAILURE AND CURRENT MILEAGE WAS 78,000.

AT A STOP LIGHT. FEELS LIKE TRANSMISSION IS NOT IN GEAR,ENGINE REVS 2500/3000RPM, THEN TRANS GOES IN GEAR. TOLD BY DEALER IF USING LEFT FOOT ON BRAKE AT A STOP, THIS WOULD CAUSE THE PROBLEM. THEY OFFERED NO HELP. WAS TOLD WITHOUT CODES THERE IS NO PROBLEM WITH TRANSMISSION! WHEN I GOT CAR IT WAS LEAKING TRANS FLUID.TOOK IT BACK TO DEALER,TO HAVE LEAK FIXED. AT ANOTHER SHOP I USE, WHILE CAR WAS ON LIFT YOU COULD SEE TRANS PAN ON VALVE BODY HAD BEEN OFF. TRANS HAS FOR SURE BEEN WORKED ON! AS YOU MIGHT GUESS IT WILL NOT DO THIS AT THE DEALER.I LET THE CAR WITH THEM FOR 1 WEEK,FOR THEM TO DRIVE.WHEN I GOT CAR BACK THEY PUT ALL OF 3MILES ON IT. *TR

REPORTED THAT CAR WOULD JERK (KICK INTO GEAR LATE) WHEN ACCELERATING FROM STOP TO START. AT 74,000 WE MADE OUR FIRST CLAIM WITH LOCAL DEALER. THEY COULDN'T DUPLICATE THE CONCERN. BROUGHT CAR IN TWO MORE TIME BECAUSE IT GOT WORSE. FELT LIKE SOMEONE WAS HITTING ME FROM THE BACK. MY CAR OFTEN KICKS OUT OF GEAR ON A LEFT TURN. ON TWO SEPARATE OCCASIONS, I WAS ALMOST T-BONED. THEY NEVER FOUND THE ISSUE UNTIL 121,000. THAT WAS WHEN THEY DECLARED THAT THE TRANSMISSION NEEDED TO BE REPLACED. GM DOESN'T WANT TO COVER THE REPAIR NOW THAT THE VEHICLE IS OUT OFWARRANTY. I HAVE RESEARCHED AND FOUND WAY TOO MANY TRANSMISSION ISSUES WITH THESE MODEL VEHICLES. GM REALLY SHOULD INVESTIGATE THIS CONCERN. I ADVISE ANYONE TO PESTER GM ABOUT THIS CONCERN. AFTERALL, WE ARE THE CONSUMERS. UNFORTUNATELY IT'S TOO LATE FOR ME, I DON'T TRUST THEIR PRODUCTS ANYMORE. *TR

SLIP IN TORQUE CONVERSION AROUND 30 TO 45. ALSO, YOU'LL BE TAKING OFF FROM A STOP AND WHEN YOU START TO PRESS THE GAS IT DELAYS, THEN SLAMS INTO MOTION ALMOST LIKE BEING HIT FROM BEHIND. * DID NOT KNOW ABOUT THIS SITE. HAD IT TO THE DEALER 3X, THEY SAID THEY FOUND NOTHING WRONG. IT IS SPORATIC AND DOES NOT HAPPEN DAILY. *TR

TL* THE CONTACT OWNS A 2007 CHEVROLET IMPALA. THE CONTACT STATED THAT THE ENGINE RPMS SUDDENLY INCREASED AS THE VEHICLE FAILED TO RESPOND TO ACCELERATION ATTEMPTS. IN ADDITION, THE TRANSMISSION HESITATED TO ENGAGE IN GEAR BUT ONCE IT DID, IT WOULD SHIFT HARD. THE VEHICLE WAS TAKEN TO THE DEALER WHO DIAGNOSED THAT THE TCC VALVE WAS LEAKING, CAUSING TRANSMISSION FLUID TO LEAK OUT OF THE TORQUE CONVERTER. AS A RESULT, THE TRANSMISSION HAD TO BE REBUILT. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 37,000 AND THE CURRENT MILEAGE WAS 39,000.

EXITING THE DARTMOUTH STREET PARKING GARAGE (UNDERGROUND) ON DARTMOUTH ST. BOSTON, MA. EXIT RAMP IS A MODERATE INCLINE. AS I APPROACHED THE GARAGE ATTENDANT BOOTH TO PAY PARKING FEE, I LET OFF THE ACCELERATOR LETTING THE CAR COAST TO A STOP WHILE I RETRIEVED THE PARKING TIME/DATE RECEIPT. WHEN I LOCATED THE RECEIPT (ABOUT 5 SECONDS) FROM THE CENTER CONSOLE I LOOKED UP TO FIND THE CAR WAS ROLLING BACKWARDS DOWN THE RAMP TOWARD A CONCRETE WALL (BY THIS TIME) APPROXIMATELY 15 MPH. NOTE: I AM A 50 YEAR OLD, (MALE) RETIRED POLICE OFFICE AND WAS TRAINED IN RADAR SPEED ENFORCEMENT INCLUDING CERTIFIED IN SPEED ESTIMATION AND I AM ALSO "EVOC" (EMERGENCY VEHICLE OPERATOR COURSE) TRAINED. I WAS ABLE TO STOP THE CAR BEFORE HITTING THE WALL, ANOTHER VEHICLE, OR ANY PEDESTRIANS. I FEEL A TRAGEDY COULD HAVE OCCURRED HAD SOMEONE BEEN WALKING IN THE GARAGE. THE CAR SEEMS TO HAVE NO ABILITY TO "HILL HOLD" WHEN IN "DRIVE" AT IDLE. I WAS SHOCKED AT HOW FAST THE AUTO ACCELERATED BACKWARD. I HAVE PERSONALLY DRIVEN APPROXIMATELY 750,000+ MILES WITHOUT AN AT FAULT COLLISION. THE CAR SEEMS TO DO THIS WHENEVER ON AN INCLINE AND ON A FEW OTHER OCCASIONS HAD OCCURRED IN PARKING LOTS ROLLING (FORWARD AS WELL AS BACKWARD) AS SOON AS SHIFTED OUT OF "PARK" IN THE FRACTION OF A SECOND TIME THAT IT TAKES TO MOVE MY DRIVING FOOT (RIGHT) FROM BRAKE (DUE TO PARK INTERLOCK) TO ACCELERATOR. NOTE: THIS AUTO IS A 2007 CHEVROLET IMPALA SS WITH 5.3L V8 ENGINE AND FOUR SPEED AUTOMATIC TRANSMISSION. MY PRIMARY CONCERN IS THAT IMPALAS ARE GENERALLY DRIVEN BY ELDERLY DRIVERS WITH SLOWER REFLEXES THAN MYSELF. I HAVE FURTHER FOUND NUMEROUS ONLINE FORUM DISCUSSIONS OF THIS ISSUE BY OWNERS OF ALL ENGINE EQUIPPED CHEVROLET IMPALAS. *TR
