TL* THE CONTACT OWNS A 2000 PONTIAC GRAND PRIX. THE CONTACT STATED WAS DRIVING APPROXIMATELY 25 MPH WHEN THE VEHICLE BEGAN JERKING ABNORMALLY AS THE VEHICLE ATTEMPTED TO SHIFT GEARS. THE VEHICLE WAS TAKEN TO THE DEALER BUT WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 90,000 AND THE CURRENT MILEAGE WAS 150,000.
MY TRANSMISSION IN MY CAR WAS LEAK OUT OF THE VENT ON TOP OF THE TRANSMISSION AND MY CAR WAS ON FIRE AND I SEE A RECALL ON THE TRANSMISSION. *TR
I HAVE A 2000 PONTIAC GRAND PRIX GP AND WHEN IT WOULD RUN FOR AWHILE, OR I WOULD DRIVE A LOT IN A DAY, THE TRANSMISSION SEEMED TO SHIFT HARDER. ON THE HIGHWAY IT WOULD BE ESPECIALLY BAD OR FROM A TRAFFIC LIGHT GOING FROM STOPPED TO HIGHWAY SPEED. IT WOULD SHIFT HARD AND SOUNDED TERRIBLE. I TOOK IT TO THE SHOP, AND THEY FOUND OUT THEY WOULD HAVE TO RE-BUILD MY TRANSMISSION! AT A TOTAL COST OF OVER $2500 TO ME! HAD I NOT TAKEN MY VEHICLE TO THE SHOP, MY TRANSMISSION WOULD HAVE EVENTUALLY FAILED, AND COULD HAVE LED TO A MORE SERIOUS ACCIDENT AND A MORE COSTLY REPAIR. *TR
I OWN A 2000 PONTIAC GRAN PRIX GT. EVERYTIME I DRIVE IT, THE SERVICE ENGINE LIGHT COMES ON AND THE TRANSMISSION SHIFTS VERY "HARD". THIS ONLY CAN BE CORRECTED IF I PULL OFF THE SIDE OF THE ROAD (WHICH CAN BE VERY DANGEROUS) AND WAIT SEVERAL MINUTES AND RESTART THE CAR. WHEN THIS HAPPENS THE RPM'S STARTS TO "REV" UP AND DOWN CONSTANTLY WHETHER WHILE DRIVING OR SETTING WHILE IN PARK. I HAVE COME CLOSE TO SEVERAL WRECKS WHEN THIS HAPPENS, ESPECIALLY WHEN THE ROADS ARE WET. BEFORE YOU KNOW IT YOU APPLY THE BREAKS ENOUGH TO SLOW DOWN FOR THE CAR IN FRONT OF YOU AND THEN THE RPM "REV" UP AND YOU ALMOST HIT THE CAR IN FRONT OF YOU IN THE REAR. I HAVE READ SEVERAL SIMILAR REPORTS AND I REALLY DON'T UNDERSTAND WITH ALL THE COMPLAINTS THIS CANNOT BE RECALLED TO FIX THIS. *TR
I OWN A 2000 PONTIAC GRAND PRIX GT ABOUT 2YRS. AGO MY TRANSMISSION FAILED ON ME. MY PROBLEM WAS DIAGNOSED BY A ASE CERTIFIED MASTER MECHANIC. I WROTE A LETTER TO GM ABOUT THIS PROBLEM,WHICH WASN'T MY ONLY GM TRANSMISSION I HAVE HAD REPLACED WITHIN A 5 YEAR TIME FRAME .I ALSO HAD TO REPLACE ONE IN A 1990 CHEVY CAVALIER Z24 THAT WAS ONLY ABOUT 9 YEARS OLD AT THE TIME AND I ALSO HAD TO REPLACE THE FUEL INJECTORS ON THAT AS WELL BUT THAT IS A WHOLE OTHER STORY. I CALLED DEALERSHIPS TO GET THE PROPER ADDRESS OF WHERE I COULD SEND MY LETTER OF DISSATISFACTION WITH GM, AND IT WAS COMPLETELY IGNORED!I DIDN'T ASK GM TO PAY FOR THE WHOLE TRANSMISSION REPLACEMENT,JUST TO MEET ME HALF WAY AND HELP A REGULAR GUY GET TO AND FROM WORK WITH A DEPENDABLE VEHICLE,TAKE CARE OF HIS FAMILY AND NOT BE HIT WITH A 2200.00 BILL THAT I AM STILL PAYING ON BECAUSE I HAD TO PUT IT ON A CREDIT CARD AND ALSO GET CHARGED INTEREST ON TOP OF THAT. GM,FORD AND CHRYSLER WONDER WHY THEY ARE LOSING THE BATTLE TO FOREIGN CARS? MY PERSONAL OPINION IS THIS SIMPLE:THEY HAVE HIGHER TOLERANCES WHEN THEIR VEHICLES ARE PUT TOGETHER RESULTING IN LESS MECHANICAL FAILURES. DON'T GET ME WRONG WHEN I FIRST ENTERED THE CAR BUYING MARKET, I LOVED AND ONLY, BOUGHT AMERICAN CARS, BUT OVER THE YEARS MY OPINION HAS BEEN SWAYED. I ALSO FEEL THAT BECAUSE MY PROBLEM WASN'T DIAGNOSED BY A MECHANIC WHO WAS EMPLOYED BY GM,THAT WAS JUST ANOTHER REASON MY LETTER WENT UNANSWERED. *JB
MY 2000 PONTIAC GRAND PRIX HAS HAD TWO FAILURES OF THE PRESSURE CONTROL SOLENOID AND THE CORRESPONDING VALVE BODY, CAUSING MY CAR TO UNEXPECTEDLY SURGE WHEN ACCELERATING. THE DEALERSHIP KEPT BOTH OLD PARTS, BUT THIS SEEMS TO BE HAPPENING TO MANY PEOPLE SO IT SHOULDN'T BE HARD TO FIND ONE. BOTH REPAIRS WERE COVERED UNDER WARRANTIES. THE FIRST ONE WAS REPLACED AT 32,000 MILES, AND THE SECOND AT 73,000 MILES. I HOPE NO ONE HAS AN ACCIDENT WHEN THIS HAPPENS, I KNOW I ALMOST DID, THE FIRST TIME IT HAPPENED I WAS SO SURPRISED I NEARLY RAN INTO ANOTHER CAR.*JB
DT: WHEN PLACING THE KEY IN THE IGNITION, THE ENGINE WILL START, BUT WHEN TRYING TO RELEASE THE KEY FROM THE IGNITION IT LOCKS. THIS RESULTS IN THE BATTERY RUNNING DOWN AND THE INABILITY TO THE LOCK CAR. TOOK CAR TO A DEALER IN APRIL 2004 AND HAD PROBLEM REPAIRED. THE DEALERSHIP REPLACED THE GEAR SHIFT INDICATOR ALONG WITH THE IGNITION LOCK RELEASE. A WEEK AGO THE EXACT SAME PROBLEM OCCURRED AGAIN. DID NOT HAVE ANY REPAIRS SINCE DISCOVERING THIS.*AK
THE VEHICLE HAS HAD A PROBLEM WITH THE TRANSMISSION SLIPPING OFF AND ON FOR ABOUT A YEAR. AAMCO COULDN'T DETECT A PROBLEM WITHOUT A CHECK ENGINE LIGHT. THE LIGHT CAME ON IN FEBRUARY 2005. THE VEHICLE NEEDED A SENSOR REPLACED AND THERE WAS A ERROR ON THE TRANSMISSION ALSO. A COMPLETE FLUID REPLACEMENT WAS DONE AND A CONDITIONER ADDED HOPING THAT THIS WOULD CURE THE PROBLEM. ON JUNE 1 THE LIGHT CAME ON AND THE SLIPPING OCCURRED AGAIN. IT LOST MERGING POWER ON THE BALTIMORE BELTWAY AND I BROUGHT IT INTO AAMCO FOR AN ANALYSIS. THEY CONCLUDED THAT THE TORQUE CONVERTER IS STUCK AS WELL AS SOME ADDITIONAL ITEM. THE CAR IS A 2000 PONTIAC GRAND PRIX WITH 83,000 MILES ON IT. I BELIEVE THAT THE POWER TRAIN WARRANTY ONLY COVERS THE VEHICLE FOR 80,000 MILES. SINCE THIS HAS BEEN AN ONGOING PROBLEM PRIOR TO THE 80,000, I WOULD LIKE TO THINK THAT GM WOULD ASSUME SOME LIABILITY FOR THE REPAIR ($1900.00). FROM SOME OF THE COMPLAINTS ON YOUR WEBSITE, I BELIEVE THAT THE TRANSMISSION IN THIS VEHICLE MAY BE DEFECTIVE IN SOME WAY.
THE TRANSMISSION IN MY 2000 PONTIAC GRAND PRIX GT HAS BEEN SHIFTING WITH A "HARD" SHIFT AFTER ABOUT 30-40 MINUTES OF TRAVEL. THIS USUALLY HAPPENS AFTER I HAVE COME TO A FULL STOP OR AFTER A SLOW TURN AS IF WHEN COMING OFF THE FREEWAY AND MERGING INTO TRAFFIC. THIS GOES AWAY AFTER I TURN THE MOTOR OFF, WAIT FOR APPROX. 10 MIN. AND RESTART THE MOTOR AND AT TIMES DOES NOT RETURN UNTIL I TRAVEL FOR A FEW MILES. *AK
THE TRANSMISSION IN MY 2000 PONTIAC GRAND PRIX STARTED SHIFTING FUNNY THEN IT WOULD SHIFT FINE AFTER SHUTTING IT OFF AND RESTARTING AFTER THIS HAPPENING A FEW TIMES I TOOK IT TO A TRANS SHOP AND THEY INFORMED ME THAT THIS A COMMON PROBLEM ON GM CARS AND THAT THE REPAIR WOULD BE $600-$700 THE CAR ONLY HAS 60,000 MILES.AFTER TALKING TO A PERSON FROM GM HE ADMITED THAT THEY HAD A BAD SUPPLIER OF PARTS FROM 1998-2000 AND THAT IF IT WAS UNDER WARRANTY THEY WOULD HAVE FIXED IT FOR FREE.WELL ITS NOT UNDER WARRANTY AND IM STUCK WITH A $600+ BILL TO FIX A PROBLEM THEY WHERE AWARE OF.THE GUY AT THE TRANS SHOP SAYS HE SEES ABOUT 3-4 OF THESE A WEEK.ALSO IF YOU DO ANY SEARCHES AND READING ON THE 4T65E TRANS YOU WILL FIND ALOT OF PEOPLE COMPLAINING OF THE SAME THING.TO FIX THIS TRANS THEY PULL IT ALMOST APART AND PUT NEW PRESSURE SOLENOIDS IN IT.*AK
I HAVE THE SAME PROBLEM AS JUST ABOUT EVERYBODY ELSE. MY TRANSMISSION HAS LOST OVERDRIVE AND SHIFTS ERRATICALLY. WHEN I AM AT 60 MPH MY RPMS ARE AT 3 AND1/2 !!! I AM READY TO START A CLASS ACTION LAWSUIT AFTER SEEING THE SAME PROBLEMS ON SO MANY CARS *NM
I WANTED TO MAKE YOU AWARE OF A POTENTIAL SAFETY HAZARD ON THE ROAD WITHIN GM VEHICLES. I ALREADY HAD TWO MAJOR TRANSMISSION REPAIRS ON CAR WITH ABOUT 75,000 MILES. THE FIRST PROBLEM OCCURRED WHEN MY CAR WAS BARELY OUT OF WARRANTY, AT APPROXIMATELY 42,000 MILES. THE TRANSMISSION STOPPED SHIFTING INTO OVERDRIVE. THIS FORCED US TO DRIVE 150 MILES BACK HOME ONLY GOING 40 MPH. THIS WEEKEND, I EXPERIENCED A TOTAL TRANSMISSION FAILURE. WHILE DRIVING ON THE FREEWAY, MY CAR SUDDENLY MADE A LOUD NOISE AND DECELERATED FROM 65 MPH TO AROUND 35 MPH IMMEDIATELY. THE DEFECT ALMOST CAUSED A MAJOR ACCIDENT AS WE WERE IN THE HIGH SPEED LANE. WHEN WE GOT OFF THE FREEWAY AND PARKED, WE REALIZED THE CAR WOULD NO LONGER GO IN REVERSE. I SHELLED OUT ALMOST $1,800 ON A REBUILT TRANSMISSION. MY REPAIR SHOP INFORMED ME THAT THEY ARE REGULARLY DOING REBUILDS ON THE SAME GM TRANSMISSION THAT IS IN MY PONTIAC. A COMMON SIGN ON THE FAILURE IS THE LOSS OF THE REVERSE GEAR. IN FACT, PARMA TRANSMISSION HAD DONE THREE ALONE DURING THE WEEK MY CAR WAS IN THE SHOP. I AM SHOCKED THAT GM WOULD INSTALL SUCH A FAULTY AND DANGEROUS PIECE OF MACHINERY ON ITS VEHICLES. I HARDLY FIND IT COINCIDENTAL THAT ALL OF THESE OWNERS ARE HAVING THE SAME PROBLEMS WITH YOUR CARS. PLEASE BE SURE NOT TO GROUP THIS PROBLEM JUST WITH PONTIAC. THEY PUT THE SAME TRANSMISSION IN MANY OF THEIR CARS, SO YOU WILL NEED TO FIGURE OUT ALL THE VEHICLES THAT ARE UNDER THIS PART NUMBER. I DID NOT KEEP THE OLD PARTS, BUT I AM SURE THE SHOP I WORK WITH WOULD BE ABLE TO START SAVING ALL OF THE DESTROYED COMPONENTS THAT THEY CONTINUALLY REPAIR. *NM
I AM HAVING THE SAME PROBLEM AS ODI ID# 10070342. TOOK TO DEALERSHIP TODAY AND WAS TOLD SHIFTER ASSEMBLY NEEDS REPLACED AT A COST OF $375. *AK
CHECK ENGINE LIGHT CAME ONE. CAR WAS SHIFTING HARD AND "JERKING." PULLED IN TO A NEARBY REPAIR SHOP AND TWO DIAGNOSTIC CODES WERE FOUND RELATING TO THE TRANSMISSION. ONE RELATED TO THE PRESSURE CONTROL SOLENOID AND THE OTHER "LONG SHIFT W/ MAX ADAPT". THEY SUGGESTED I TAKE IT TO A TRANSMISSION SHOP. I THEN TOOK THE VEHICLE TO MY REGULAR MECHANIC, HE COULD NOT DUPLICATE THE PROBLEM NOR COULD HE FIND ANYTHING WRONG AT THAT TIME. HE ALSO SUGGESTED I TAKE IT TO A SHOP SPECIALIZING IN TRANSMISSIONS. I DID. THEY ALSO COULD NOT DUPLCATE THE PROBLEM OR FIND ANYTHING OTHER THAN METAL SHAVINGS IN THE PAN. THEY SUGGESTED I HAVE THE TRANSMISSION COMPLETELY REBUILT AT A COST OF OVER $2,100.00.*AK
TRANSMISSION 63,000 MILES, PRESSURE CONTROL CYLINOID GOES OUT AND TAKES 2ND AND 4TH GEAR WITH IT RESULTING IN NEEDING A NEW TRANSMISSION.*AK
TRANSMISSION STARTED SHIFTING VERY HARD AT 33000 MILES TRYING TO GET GM TO PAY FOR THE REPAIRS.*AK
2000 PONTIAC GRAN PRIX. APPROX 80,000 MILES. VEHICLE JERKS DURING GRADUAL ACCELERATION. PONITAC DEALER DIAGNOSED PROBLEM AS BAD PRESSURE CONTROL SOLENOID AND BAD TCC SOLENOID. PARTS AND SERVICE TO COST $700.00. NOT ACCEPTABLE FOR A 4 YEAR OLD VEHICLE.*AK
SLIPPAGE IN FORWARD, REVERSE, METAL DEBRIS IN TRANS PAN - BAD TRANSMISSION
WHILE DRIVING 35 MPH VEHICLE STALLED IN THE MIDDLE OF THE HIGHWAY. AFTER SEVERAL ATTEMPTS TO RESTART THE VEHICLE CONSUMER CALLED FOR A TOW TRUCK. DEALER EXAMINED THE VEHICLE, AND DETERMINED THAT A NEW TRANSMISSION WAS NEEDED. *AK
TRANSMISSION WAS REBUILT/REPLACED AT 27,000 MILES (THIS WAS UNDER WARRANTY). NOW AT 86,000 MILES TRANSMISSION HAD TO BE REBUILT DUE TO A GASKET BLOW THAT CAUSED ALL THE FLUID TO LEAK OUT WHICH THEN CAUSED INTERNAL PROBLEMS. THIS IS A VERY COSTLY DEFECT THAT I FEEL MAY HAVE TO DO WITH A DEFECT FROM THE MANUFACTURER. A $28,000 CAR SHOULD NOT HAVE A MAJOR DEFECT OF THIS MAGNITUDE TWICE BEFORE IT EVEN REACHES 100,000 MILE. THIS SHOULD BE INVESTIGATED BY GM BECAUSE I AM NOW SEEING THAT I AM NOT THE ONLY ONE WITH THIS PROBLEM. GM SHOULD HAVE TO PAY FOR THIS EXPENSIVE REPAIR. *LA
CAR HAS ERRATIC SHIFTING, JERKS WHEN ACCELERATING. TAKEN TO DEALERSHIP AND DIAGNOSED AS PRESSURE CONTROL SOLENOID. WHEN THE TRANS PAN WAS TAKEN OFF THERE WAS SIGNIFICANT AMOUNTS OF METAL SHAVINGS. THE TRASNMISSION WAS THEN TAKEN APART AND FOUND THAT THE CLUTCH AND MANY GEARS WERE DAMAGED BECAUSE OF THE METAL. GM WAS CONTACTED FOR ASSISTANCE AND THEY SAID THEY WOULDN'T GUARANTEE THERE DEFECTIVE PARTS BECAUSE THEY CAN NOT DETERMINE HOW THE PREVIOUS OWNER TOOK CARE OF THE CAR.*AK
AUTOMATIC TRANSMISSION SENSOR FAILED WHICH CAUSED TRANSMISSION TO HESITATE WHEN SHIFTING GEARS WHILE DRIVING. *AK THE TRANSMISSION SHIFTED HARD EVERY TIME AND THERE WOULD BE A HARD JERK. (LINE PRESSURE RISE PROBLEM/NEEDED VALVE BODY REPAIRS) *SCC *JB
2000 PONTIAC GRAND PRIX GTP HAS 42,000 MILES. WE PURCHASED THIS VEHICLE NEW IN JANUARY OF 2000. NO SIGN OF TRANSMISSION FAILURE. GOING FROM A STOP LOUD CLANKING NOISE, CAR JERKED 3 OR 4 TIMES. 5 MINUTES LATER AFTER ANOTHER STOP SIGN THE CAR DID THE SAME THING AGAIN. I STOPPED TO A REPAIR STATION, WHEN I PUT THE CAR IN PARK IT MAKES AN AWFUL GRINDING NOISE WHILE IDLING. THE SERVICE TECHNICIAN TOOK THE CAR FOR A DRIVE AND SAID TO GET IT TO A GM DEALER BECAUSE THE TRANSMISSION IS GOING. I WAS TOLD THIS SHOULD NOT HAVE HAPPENED ON A CAR THAT ONLY HAS 42,000 MILES ON IT. AS I AM LOOKING THROUGH THE CONSUMER AFFAIRS COMPLAINT DATA BASE I AM SEEING 9 COMPLAINTS THAT ARE QUITE SIMILAR. HOW MANY COMPLAINTS DOES IT TAKE TILL THIS TRANSMISSION PROBLEM IS RECALLED? I PAID $27,000.00 FOR MY CAR 3 1/2 YEARS AGO AND SHOULD NOT HAVE TO PUT $2,000.00 INTO IT ALREADY. I PURCHASE NEW CARS SIMPLY BECAUSE OF FEELING SECURE KNOWING THAT I TAKE CARE OF MY CARS WITH REGULAR OIL CHANGES AND MAINTENANCE AND WOULD NOT HAVE TO WORRY ABOUT ANY MAJOR REPAIRS. I WOULD LIKE THIS RESOLVED BY GM REPAIRING MY VEHICLE AT THEIR EXPENSE. *LA
AUTOMATIC TRANSMISSION WOULD NOT SHIFT INTO OVERDRIVE. TRANSMISSION NEEDS REBUILD AT 55,000 MILES.
PROBLEMS WITH TRANSMISSION. THE VEHICLE EXPERIENCED PROBLEMS WITH IT'S ENGINE AND TRANSMISSION WHICH CAUSED THE VEHICLE TO LUNGE AT GEARSHIFT. WHEN THE TRANSMISSION FLUID WAS BEING CHANGED ALOT OF UNUSUAL METAL SHAVINGS WERE FOUND IN THE TRANSMISSION FLUID PAN. *NLM
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
