2006 Chevrolet Impala Power Train

WHEN STEPPING ON THE GAS HARD FROM A STOP IT TAKES TIME FOR SOMETHING TO CATCH THEN IT JERKS AND GOES, WHEN SPEEDING UP WHEN DRIVING, IT JERKS REAL HARD WHEN IT SHIFTS. BAD TRANSMISSION. LEAKS OIL, HEADLIGHTS COME ON IN THE MIDDLE OF THE NIGHT, DRAINS THE BATTERY. THIS CAR IS A P.O.S. *TR

TL* THE CONTACT OWNS A 2006 CHEVROLET IMPALA. THE CONTACT STATED THAT HE WAS UNABLE TO REMOVE THE KEY FROM THE IGNITION. THE VEHICLE WAS TAKEN TO A DEALER FOR DIAGNOSIS AND THE CONTACT WAS INFORMED THAT THE CAUSE OF THE FAILURE WAS A WIRE THAT CONNECTED TO THE SHIFT SOLENOID. THE MANUFACTURER WAS NOTIFIED BUT STATED THERE WERE NO RECALLS FOR THE VIN. THE VEHICLE HAD NOT BEEN REPAIRED. THE FAILURE MILEAGE WAS 47,000 AND THE CURRENT MILEAGE WAS 109,000.

IN THE FALL OF 2010, I TOOK MY 2006 CHEVY IMPALA SS TO A CHEVY DEALER FOR AN OIL CHANGE. WHILE WAITING FOR MY VEHICLE, I WAS ADVISED BY THE MECHANIC I SHOULD HAVE THE TRANSMISSION FLUSHED. I QUESTIONED HIM BECAUSE THERE WAS ONLY 60K MILES ON THE CAR, ALSO, HAD NOT NOTICED ANYTHING WHILE DRIVING THAT WOULD INDICATE THAT BEING NEEDED. I HAD THE FLUSH DONE ANYWAY, AND, SINCE THEN, THE TRANSMISSION BEGAN SLIPPING FROM A COMPLETE STOP. IT WASN'T BAD AT FIRST, ONLY HAPPENED ONCE IN A GREAT WHILE. I TOOK THE CAR TO THE SAME SHOP THAT FLUSHED THE TRANSMISSION TO CHECK ON IT, ONLY TO HAVE THEM TELL ME THERE WAS NO PROBLEM AND THEY WERE UNABLE TO REPLICATE THE PROBLEM. I NOW HAVE 80K MILES ON THE CAR AND THE PROBLEM IS GETTING WORSE, THE SLIP HAPPENS ALMOST EVERY TIME I ACCELERATE FROM A DEAD STOP AND I ALSO FEEL TORQUE SHUDDER WHILE AT HIGHER SPEEDS. I HAVE DONE RESEARCH AND THIS SEEMS TO BE A COMMON ISSUE. I AM DRIVING THE CAR BUT AM VERY NERVOUS DOING SO. I FEEL THIS CAN BE A SERIOUS SAFETY ISSUE NOT KNOWING WHEN THE TRANSMISSION WILL ENGAGE OR DISENGAGE. *TR

TRANSMISSION SLAMS INTO GEAR FROM A START. TRANSMISSION WILL SLIP WHILE STOPPED THEN JERK INTO GEAR AND ACCELERATE ROUGHLY. DEALER WILL NOT COVER AS IT IS INTERMITTENT. *TR

TL* THE CONTACT OWNS A 2006 CHEVROLET IMPALA. THE CONTACT STATED THAT AFTER EXITING FROM A STOP LIGHT, THE VEHICLE LUNGED FORWARD AS THOUGH THE TRANSMISSION WAS SLIPPING. THE VEHICLE WAS TAKEN TO A MECHANIC WHO STATED THERE WAS A VALVE IN THE TRANSMISSION THAT FAILED AND NEEDED TO BE REPLACED. THE MANUFACTURER WAS NOTIFIED OF THE ISSUE WHO STATED THERE WERE NO RECALLS FOR THE VEHICLE AND OFFERED NO OTHER ASSISTANCE. THE FAILURE MILEAGE WAS 63,000.

TL* THE CONTACT OWNS A 2006 CHEVROLET IMPALA. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 25 MPH, THE CHECK ENGINE LIGHT ILLUMINATED ON THE INSTRUMENT PANEL AND THE VEHICLE BEGAN TO SHAKE VIOLENTLY. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC FOR A DIAGNOSTIC TEST. THE MECHANIC CLEANED THE THROTTLE BODY. THE FAILURE CONTINUED AFTER THE REPAIR. THE VEHICLE WAS TAKEN BACK TO AN INDEPENDENT MECHANIC AND THE DEALER APPROXIMATELY EIGHT DIFFERENT TIMES. THE VEHICLE WAS REPAIRED WHEN THE PCM WAS REPLACED AND REPROGRAMMED AT THE DEALER. THE APPROXIMATE FAILURE MILEAGE WAS 80,000.

TRANSMISSION SLIPPING, HARD SHIFTS, BROKEN MOTOR MOUNTS. TRANSMISSION ACTS LIKE IT'S NOT IN GEAR, DOESN'T ENGAGE UNTIL ABOUT 2,000 RPM THEN SLAMS INTO GEAR. ALSO SLIPS WHEN SHIFTING FROM 1ST TO 2ND AND AGAIN WHEN IN 4TH GEAR. *TR TRANSMISSION FAILURE, THE TRANSMISSION FAILS TO FULLY ENGAGE IN TO ANY GEAR WHEN IT IS SUPPOSED TO, IT WILL SLIP AND CATCH FROM A STOP, THE TORQUE CONVERTER FAILS TO LOCK UP AND ALL GEARS SLIP UNDER MODERATE TO HEAVY ACCELERATION.

INTERMITTENTLY USUALLY FROM A STOP CAR ACTS LIKE ITS IN NEUTRAL REVS UP AND ALL OF A SUDDEN BANGS INTO GEAR AND TAKES OFF. VERY DANGEROUS WHEN IN TRAFFIC AND IT UNEXPECTEDLY DOES IT WHEN YOUR TRYING TO INCH FORWARD. ALMOST CAUSES A REAR END COLLISION BECAUSE ITS INTERMITTENT. I AM AFRAID I WON'T CATCH IT IN TIME. SOMETIMES IT GOES FOR DAYS WITHOUT DOING IT AND YOU GET COMFORTABLE WITH IT THEN WAMMO. TOOK IT TO MY SHOP AND THEY TELL ME IT COULD BE A TRANS PROBLEM. BOUGHT CAR BRAND NEW AND ITS HAPPENED BEFORE BUT SEEMS TO BE GETTING WORSE. *TR

TL* THE CONTACT OWNS A 2006 CHEVROLET IMPALA. THE CONTACT WAS AT A STOP SIGN WHEN THE ENGINE RPMS INCREASED EXCESSIVELY AS THE VEHICLE ABNORMALLY ACCELERATED. THE VEHICLE WAS TAKEN TO THE DEALER WHERE THE DEALER CONFIRMED THAT THE TRANSMISSION NEEDED TO BE REPLACED. THE MANUFACTURER WAS CONTACTED BUT THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 51,000 AND THE CURRENT MILEAGE WAS 51,497.

WHEN I START FROM A STOP THE TRANSMISSION DOES NOT FULLY ENGAGE FOR A FEW SECONDS. IF I STEP ON THE GAS, IT ROLLS SLOWLY FORWARD, BUT ONCE IT CATCHES IT JERKS FORWARD REALLY HARD. I'VE KNOW 2 OTHERS WITH THIS SAME ISSUE, AND THE TRANSMISSION SHOP SAYS IT'S PRETTY COMMON WITH THESE. CHEAP PART TO REPLACE (CLUTCH GASKET OR SOMETHING), BUT $1700 IN LABOR. I'M READY FOR A RECALL... *JS

ON TUESDAY MORNING ON THE FREEWAY I NOTICED THE RPMS IN MY 2006 IMPALA SS JUMPING, I PUSHED ON THE GAS PEDAL TO ACCELERATE AND MY TRANSMISSION WAS SLIPPING IN OVERDRIVE. IS MY TRANSMISSION GOING OUT ALREADY? THE CAR HAS 63000 MILES ON IT. *TR

2006 IMPALA SS, TRANSMISSION SLIPPING, AND NOT ACCELERATING WHEN INITIALLY DEPRESSING ACCELERATOR. VEHICLE MAINTAINED APPROPRIATELY AT DEALERSHIP. THE FILTER AND FLUID CHANGED AT RECOMMENDED INTERVALS. I HAVE MONITORED SIMILIAR COMPLAINTS FROM OTHER IMPALA OWNERS. THE TRANSMISSION THAT CHEVROLET DEVELOPED FOR THE IMPALA LS-LT-SS. DOES NOT APPEAR TO BE A QUALITY PART. AND IF CHEVROLET DOES NOT DO A BETTER JOB OR ATTEMPT TO MAKE THIS SITUATION BETTER, I TO WILL MOVE ON TO A FOREIGN MANUFACTURER. I HAVE BEEN A GM OWNER ALL OF MY LIFE. I STILL OWN MY 1988 OLDSMOBILE CUTLAS. THIS SITUATION WITH ALL OF THESE COMPLAINTS "IS JUST WRONG"

TL* THE CONTACT OWNS A 2006 CHEVROLET IMPALA. THE CONTACT STATED THAT SHE ATTEMPTED TO ACCELERATE FROM A STOP WHILE POSITIONED ON AN INCLINE, THE VEHICLE MOMENTARILY HESITATED BEFORE RAPIDLY ACCELERATING. THE CHECK ENGINE LIGHT BEGAN TO ILLUMINATE AFTER THE FAILURE. THE VEHICLE WAS TAKEN TO AN INDEPENDENT REPAIR SHOP AND THE CONTACT WAS INFORMED THAT THERE WAS A FAILURE WITHIN THE TRANSMISSION. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED AND THE CONTACT WAS AWAITING A RESPONSE. THE FAILURE MILEAGE WAS 109,000.

TRANSMISSION FAILURE CLUTCHES WORN SLIPPING, HAD TO HAVE WHOLE TRANNY REBUILT, TOOK IT TO CHEVY DEALER 8 MONTHS AGO AFTER IT WAS SLIPPING AND BANGING INTO GEAR AND WHINING NOISE (WHICH WAS THE BEARING IN THE TRANSMISSION BEING WORN, CHEVY DEALER SAID NOTHING WRONG SENT ME HOME.. 8MONTHS LATER AND $2,600 LATER HAD TO HAVE IT REBUILT BY PRIVATE TRANSMISSION SHOP. *TR

2006-2009 CHEVROLET IMPALA SS, 2006-2007 CHEVROLET MONTE CARLO SS, 2005-2008 PONTIAC GRAND PRIX GXP AND 2007-2008 BUICK LACROSS SUPER WITH THE LS4 5.3L V8 ENGINE AND THE 4T65E-HD TRANSMISSION MN7. THE LS4 V8 ENGINE IS RATED BY GM AT 323 LB-FT OF TORQUE. ALLEGEDLY, THE DOCUMENTS FROM GM FOR THE TRANSAXLE MATED TO THIS MOTOR IS ONLY RATED FOR 280 LB-FT OF ENGINE TORQUE; 43 LB-FT OF TORQUE LOWER THAN THE OUTPUT OF THE ENGINE. THIS COULD POSSIBLY LEAVE A VEHICLE EQUIPPED WITH THIS MOTOR AND TRANSAXLE COMBINATION WITH A HIGH FAILURE RATE AND A POSSIBLE SAFETY HAZARD WHILE IN TRAFFIC.

I HAVE A 2006 CHEVY IMPALA AND THERE SEEMS TO BE A PROBLEM WITH THE TRANSMISSION. I HAVE TAKEN THE CAR TO THE DEALER SEVERAL TIME AND HAVE EVEN HAD THE TRANSMISSION FLUSHED BUT AM STILL HAVING THE CAR JERK OFF AT A STOP LIGHT. THE DEALER CAN NEVER FIND A PROBLEM AND IT SEEMS TO BE GETTING WORSE. I AM PART OF AN CHEVROLET FAMILY AND WE HAVE A TOTAL OF 8 IMPALA AND WE ALL SEEM TO BE EXPERIENCING THE SAME PROBLEM. ALSO THE POWER STEERING BELTS AND PULLEY ALWAYS MAKE A HISSING SOUND WHEN THE STEERING WHEEL IS TURNED AND HAVE HAD THIS LOOKED AT AND HAVE HAD THE HOSE REPLACE SEVERAL TIMES ONLY TO HAVE THE PROBLEM TO REAPPEAR. IS THERE A RECALL ON THESE ISSUES. HAVING TO PAY OUT OF POCKET FOR THESE THINGS NOW AS MY CAR IS OUT OF WARRANTY NOW. *TR

TL* THE CONTACT OWNS A 2006 CHEVROLET IMPALA. THE CONTACT STATED THE VEHICLE SEEMED TO HESITATE RANDOMLY WHEN ACCELERATING FROM A STOP LIGHT.

THE DEALER STATED THEY WOULD HAVE TO PULL THE TRANSMISSION APART TO MAKE THE REPAIR. THE FAILURE MILEAGE WAS 75,000 AND THE CURRENT MILEAGE 95,000. UPDATED 10/03/2011 *LN *TR

TRANSMISSION HAS BEEN REBUILT ONCE, THEN SUBSEQUENTLY REPLACED WITH A REMANUFACTURED UNIT FROM GENERAL MOTORS. THIS REMANUFACTURED TRANSMISSION IS NOW DISPLAYING ANOMALOUS BEHAVIOR. PRIOR TO EACH FAILURE, THE TRANSMISSION EXHIBITED A VARIETY OF INCORRECT BEHAVIOR, INCLUDING RAPID TORQUE CONVERTER CLUTCH LOCKING AND UNLOCKING, SLIPPING AND REVVING FROM A STOP, WITHOUT THE CAR MOVING, THEN SUDDENLY SLAMMING INTO GEAR WITH THE CAR MOVING AWAY FROM REST. THE MOST RECENT ISSUE HAS BEEN AN OSCILLATION ON 4-3 DOWNSHIFTS AT APPROXIMATELY 60 MPH, AS WELL AS EXCESSIVE TRANSMISSION HEAT BUILD-UP WITH THE TORQUE CONVERTER UNLOCKED. THE FIRST TIME THE TRANSMISSION DISPLAYED ODD BEHAVIOR, WHICH WAS TORQUE CONVERTER LOCK AND UNLOCK AT CRUISING SPEEDS, DEALER DROVE THE CAR ACKNOWLEDGED THE PROBLEM, AND UPON DISASSEMBLY, FOUND TORQUE CONVERTER CLUTCH MATERIAL IN THE PAN. THEY REBUILT THE TRANSMISSION WITH NEW SOFT PARTS AND REPLACED THE CONVERTER. VEHICLE HAD 59,000 AND THIS WAS ALL PERFORMED UNDER WARRANTY. ABOUT 23,000 MILES LATER, WHEN PULLING AWAY FROM A STOP, THE ENGINE WOULD REV UP MOMENTARILY, BUT THE CAR WOULD NOT MOVE. IT WOULD THEN SLAM INTO GEAR AND MOVE OFF. DEALER CONFIRMED ISSUE, DISASSEMBLED, AND DETERMINED THAT THE TORQUE CONVERTER CLUTCH HAD AGAIN FAILED. DEALER REPLACED TRANSMISSION WITH A REMANUFACTURED UNIT. THIS WAS ALL DONE UNDER WARRANTY. VEHICLE HAD APPROXIMATELY 86000 MILES AT THIS TIME. IMMEDIATELY UPON RECEIVING CAR BACK AFTER REPLACEMENT OF TRANSMISSION, NOTED OSCILLATION ON 4-3 DOWNSHIFTS, AS WELL AS MUCH HIGHER TRANSMISSION TEMPERATURES WITH CONVERTER UNLOCKED (ABOUT 40 DEGREES HIGHER), AS WELL AS EXCESSIVE LOOSENESS OF THE TORQUE CONVERTER. RETURNED TO DEALER, WHO CLAIMED ALL WAS NORMAL. SINCE THAT TIME, WARRANTY HAS EXPIRED. THE OSCILLATION AND HEAT ISSUES HAVE WORSENED, AND THE CAR IS NOW BEING SERVICED AT AN INDEPENDENT SHOP AND HAVING A PARTIAL REBUILD. *TR

TRANSMISSION SLIPPING AND FINALLY NO FORWARD OR REVERSE GEARS. BROKE DOWN MONDAY MORNING AFTER BEING INTO GM DEALER FRIDAY FOR A CHECK UP WITH NO PROBLEMS OR ISSUES FOUND. *TR

2006 IMPALA 3.5 ,NOISE AND VIBRATIONS FROM TRANSAXLE AND OR CV JOINTS,THIS HAPPENS AT ALL SPEEDS AND THE NOISE GETS LOUDER WHEN TURNING LEFT, I HAVE'NT DONE ANYTHING TO CORRECT THE PROBLEM. *TR

IMPALA "SS" WITH ONLY APPROXIMATELY 71,000 MILES, MAJOR TRANSMISSION MALFUNCTION / FAILURE WITHOUT ANY PRIOR WARNING. VEHICLE HAD ONLY BEEN SERVICED AT GM DEALERSHIP SINCE PURCHASED, ALL REGULAR MAINTENANCE FOLLOWED. TRANSMISSION SLIPPAGE COMBINED WITH HARSH SHIFTING, TORQUE CONVERTER SHUDDER, GRINDING NOISES FROM GEARS. VEHICLE WOULD ALTERNATE BETWEEN NOT GOING FORWARD OR, ONCE MOVING, VERY DIFFICULT TO STOP VEHICLE BECAUSE TRANSMISSION DID NOT DISENGAGE (NEARLY REAR ENDED OTHER VEHICLES, HAD TO STAND ON BRAKE PEDAL). NO WARNING LIGHTS NOR DASH INDICATORS, BUT REMOTE DIAGNOSTIC VIA ONSTAR CONFIRMED TRANSMISSION FAILURE AND DIRECTED FOR IMMEDIATE REPAIR. VALVE BODY, PRESSURE REGULAR, ALL SOLENOIDS (REBUILD) REPLACED UNDER GMPP EXTENDED WARRANTY COVERAGE. NOT EVEN TWO WEEKS LATER, PROBLEMS RETURNED BUT WORSE. NHTSA CAMPAIGN # 10021844 AND TSB # 070730012C SEEM TO ADDRESS THIS ISSUE. VEHICLE NOW AT GM DEALERSHIP BEING ASSESSED. ONSTAR DIAGNOSTICS FOUND NO ISSUE. STILL NO WARNING INDICATORS, BUT VEHICLE HAVE HIGH RPM WITHOUT ANY FORWARD MOTION WHEN ACCELERATOR DEPRESSED. RPMS WOULD ALSO BOUNCE UP AND DOWN ERRATICALLY ON HIGHWAY AT STEADY SPEED, VIBRATIONS AND WHINING NOISES FROM TRANSMISSION. APPARENTLY THIS IS KNOWN DEFECT WITH MULTIPLE VEHICLES EQUIPPED WITH THE 4T65-E TRANSMISSION, BUT THERE HAS NEVER BEEN ANY RECALL. COST OF REPAIRS FOR THIS BETWEEN $4,000 AND $6,000 IF NOT UNDER WARRANTY. THIS LIKELY EFFECTS HUNDREDS OF THOUSANDS OF GM VEHICLES COVERING MANY MODEL YEARS. *TR

I HAVE A 2006 IMPALA SS. THE CAR WAS PURCHASED USED WITH APPROXIMATELY 12K MILES, IN EARLY 2009 AT 62K THE TRANSMISSION FAILED, STRANDING MY FAMILY ON THE PA TURNPIKE. IN JANUARY 2011 AT 101K WE HAD TO REPLACE THE TRANSMISSION AGAIN. LUCKILY WE PURCHASED A GM POWER-TRAIN TRANSMISSION AND IT CAME WITH A 3YR WARRANTY. THE FAILURE SYMPTOMS WERE IDENTICAL FOR EACH OCCURRENCE. 1ST THE TRANSMISSION WOULD OCCASIONALLY SHUDDER WHILE SHIFTING. EVENTUALLY IT WOULD SHUDDER AND PREDICTABLY SLIP WHEN MAINTAINING A SPEED AT OR NEAR 1800 RPM. THIS WAS ESPECIALLY NOTICEABLE DRIVING UP HILLS. FINALLY THE CAR WOULD NOT MOVE WHILE THE ENGINE RPM SPIKED WHEN PRESSING THE ACCELERATOR PEDAL. THE ENTIRE FAILURE PERIOD WAS AROUND 1000 MILES FROM THE 1ST SIGN THAT THE TRANSMISSION WAS HAVING DIFFICULTY TO SHIFTING TO THE FINAL FAILURE. THE TRANSMISSION APPEARS TO REACH VERY HIGH TEMPERATURES AND HAS A LONG COOL OFF PERIOD. WHEN REPLACING THE POWER STEERING GEAR I NOTICED THAT THE EXHAUST AND ENGINE WERE COOL TO THE TOUCH, BUT THE TRANSMISSION REMAINED WARM THROUGH OUT THE REPAIR. THANK FOR YOUR ATTENTION IN THIS MATTER. *TR

CAR STARTED RUNNING SLUGGISH MORE AND MORE UNTIL THE TRANSMISSION DIED AND NEEDS A REBUILD. TAKEN TO A SHOP TO GET IT REBUILT. *TR
