2006 Chevrolet Impala Power Train

I AM WRITING TO COMPLAIN ABOUT THE 4T65E-HD TRANSMISSION IN GENERAL MOTOR'S LINEUP OF V8 POWERED W-BODY PLATFORM CARS. I HAVE EXPERIENCED MANY ISSUES OF THIS TRANSMISSION SLIPPING AND HESITATING ON ACCELERATION FROM A STOP. I HAVE BEEN EXPERIENCING THE ISSUE FOR ABOUT 30K MILES NOW. THE CAR IS NOT BEATEN, OR DRIVEN HARD AT ALL. ALL MY ROUTINE MAINTENANCE HAS BEEN DONE. I FIRST TOOK IT TO THE DEALER TO COMPLAIN ABOUT THE SLIPPING TRANSMISSION, AND EVEN THOUGH THE TECH FELT THE TRANSMISSION ISSUE, I WAS TOLD THAT UNLESS THE TRANSMISSION IS THROWING A CODE, THERE IS NOTHING THAT THEY COULD DO FOR ME. I HAVE PUT ABOUT $500 INTO WORK ON THIS TRANSMISSION SO FAR WITH MINIMUM SUCCESS. I HAVE FLUSHED THE TRANSMISSION TOTALLY, WHICH SEEMED TO HAVE FIXED THE TRANSMISSION FOR ABOUT A WEEK. ANOTHER THING THAT I ATTEMPTED PER THE RECOMMENDATION OF A GM MASTER TECH WAS TO CHANGE THE VALVE BODY. WHICH I DID AND IT CORRECTED THE ISSUE FOR 3 DAYS. NOW THE TRANSMISSION IS SLIPPING WHEN DRIVING ON THE HIGHWAY AT A CONSTANT SPEED/RPM.. ALMOST LIKE IT FEELS THE MOTOR IS MISFIRING. I HAVE CHECKED THE FLUID LEVEL, AND THE FLUID. THE LEVEL IS FINE AND THE FLUID IS NOT BURNT. I FEEL THAT GM NEEDS TO STEP UP AND RECTIFY THE PROBLEM OF THESE GARBAGE TRANSMISSIONS. I HAVE OWNED 2 OTHER CARS WITH THE SAME TRANSMISSION (95 MONTE CARLO Z34 AND A 01 PONTIAC GTP). BOTH VEHICLES EXPERIENCED THESE SAME ISSUES AND THE TRANSMISSIONS BLEW UP. WHY WOULD GM CONTINUE TO USE SUCH A WEAK MAJOR COMPONENT. I KNOW OF 100+ OTHER V8 W-BODY OWNERS EXPERIENCING THESE SAME ISSUES. *TR

TRANSMISSION LUNGES FROM A DEAD STOP UPON ACCELERATION. DOES NOT MOVE WITH INCREASED RPMS UNTIL TORQUE CONVERTER BANGS. PROBLEM HAS EXISTED SINCE PURCHASE IN 2006 WITH 11,000 MILES. TAKEN TO DEALER MULTIPLE TIMES WITH NO PROBLEM FOUND. MULTIPLE COMPLAINTS WITH THIS PER INTERNET SEARCH. CHEVROLET EVIDENTLY WILL NOT OWN UP TO THIS PROBLEM. *TR

MY 2006 CHEVY IMPALA SS WAS RECALLED FOR A POWER STEERING OIL LINE LEAK. WHEN IT WAS ON THE LIFT, IT WAS DISCOVERED THAT THE OIL LINE ON THE TRANSMISSION ALSO LEAKED. THE LINE LEAKED WHERE THE RUBBER LINE WAS CRIMPED ONTO A METAL LINE. THE DEALER STATED THAT THEY HAD REPLACED SEVERAL OF THESE. IT WAS NOT COVERED BY WARRANTY. SINCE THERE WAS NO OIL DRIPPING ONTO MY CONCRETE DRIVEWAY, I ASSUME THAT IT LEAKS UNDER PRESSURE. THIS IS A DEFECTIVE PART. *TR

GM 2006 IMPALA TRANSMISSION FAILURE. UPON INITIAL OPERATION TRANSAXLE SHUDDERS, STUTTERS, AND STALLS UPON ACCELERATION DEMAND. FAILURE CREATES AN UNANTICIPATED AND WARNING-LESS SLOW-DOWN OF MY VEHICLE DIRECTLY IN FRONT OF OTHER ACCELERATING VEHICLES. A SAFETY HAZARD RESULTS FROM POSSIBLE REAR-ENDING BY FOLLOWING MOTORISTS THAT HAVE TO BE UNAWARE THE CAR IN FRONT OF THEM HAS STUTTERED AND SLOWED DOWN. IT ALSO IS A PROBLEM FOR DRIVERS AS THEY CANNOT ACCELERATE OR PASS OTHER CARS, AND CANNOT SAFELY OR CONFIDENTLY EVADE ROAD OBJECTS/DEBRIS/POTHOLES. A REVIEW OF THIS TRANSAXLE PROBLEM INDICATES MANY GM MOTORISTS SHARE THE SAME PROBLEMS AND VOICE THE SAME CONCERNS. *TR

TRANSMISSION PROBLEMS.. JERKING WHEN TRYING TO BACK IN A PARKING SPACE. SEALS HAD TO BE REPLACE DUE TO A TRANSMISSION LEAK. *TR

I AM A POLICE OFFICER AND HAVE HAD SEVERAL OCCASIONS WHILE ON TRAFFIC STOPS, THAT MY ASSIGNED 2006 IMPALA HAS ROLLED BACKWARDS AFTER I HAD GOTTEN OUT OF THE CAR TO APPROACH A TRAFFIC VIOLATOR; I HAD TO JUMP BACK IN AND PUT IT BACK IN PARK.. ON 10/ 04/07 THIS CAR ALMOST COST ME MY LIFE. I BLOCKED AN ENTRANCE RAMP AND WHEN I GOT OUT OF THE CAR I STOOD BY THE OPEN DRIVER DOOR. THE CAR JUMPED INTO GEAR AND BACKED OVER ME. I WAS DRUG BACKWARDS AND COULD NOT FREE MYSELFAS I WAS BEING HELPLESSLY DRAGGED UNDER MY CAR. WHEN THE CAR WENT INTO THE MEDIAN IT DUG MY BODY INTO THE DIRT. I WAS ABLE TO ROLL FROM UNDERNEATH THE CAR. I THEN JUMPED BACK IN AND STOPPED THE CAR FROM CROSSING THE EXPRESSWAY. I HAVE BEEN ON THE STREETS AS A BEAT OFFICER FOR OVER 21 YEARS AND HAVE NEVER HAD ANYTHING LIKE THIS HAPPEN. I SPOKE WITH ANOTHER OFFICER AND HE ALSO HAS HAD THE SAME PROBLEM WHILE ON TRAFFIC STOPS. I WAS ADVISED BY FLEET MANAGEMENT THAT THERE HAS BEEN ONE OTHER INCIDENT REPORTED. MY PATROL CAR WAS TOWED ON OCT 8 AND LATER I WAS ADVISED BY FLEET MANAGEMENT THAT GM REPS LOOKED AT THE CAR AND FOUND NOTHING WRONG. FLEET MANAGEMENT PERSONNEL REFUSE TO GIVE ME ANY INFORMATION AS FOR A CONTACT PERSON WITH GM. NOTE -AS OF 10/19/07 THEY STILL HAVE THE CAR UNDER LOCK AND KEY. I SUSTAINED ROAD RASH, BRUISING, CERVICAL STRAIN, AND A POSSIBLE FRACTURE IN MY BACK. I HAVE CONTACTED MY LOCAL FRATERNAL ORDER OF POLICE PRESIDENT AND HE HAS BEEN GATHERING INFORMATION AS TO SEVERAL OTHER OFFICERS THAT HAVE HAD THEIR ASSIGNED 2006 IMPALA GO OUT OF GEAR AND STRIKE OBJECTS. IN ADDITION THEY HAD BEEN CHARGED WITH THE ACCIDENTS AND POINTS ASSESSED. PER MY FOP PRESIDENT AN INVESTIGATION IS BEING DONE TO REMOVE THOSE OFFICERS POINTS AND DICIPLINARY ACTION PER MY UNFORTUNATE INCIDENT. MY CONCERN NOW IS FOR THE SAFETY OF THE CITIZENS ON A NATIONAL LEVEL, WHILE THESE CHEVY IMPALAS ARE BEING USED FOR PUBLIC SAFETY. *TR

NEW 2006 CHEVY IMPALA TRANSMISSION DOES NOT ENGAGE UPON ACCELERATION AFTER COMING TO A COMPLETE STOP WHEN TRANSMISSION IS COLD. THIS CAUSES HESITATION UPON ACCELERATION AFTER STOP SIGNS AND TRAFFIC LIGHTS. *JB

CENTER CONSOLE SHIFT BUTTON STICKING, MAKING DIFFICULT TO SHIFT FROM PARK TO DRIVE. *JB
