2004 GMC SIERRA Power Trainautomatic Transmission Problems

TL* THE CONTACT OWNS A 2004 GMC SIERRA. THE CONTACT STATED THAT THE VEHICLE JERKED VIOLENTLY. THE VEHICLE WAS TAKEN TO THE DEALER FOR INSPECTION WHERE THEY STATED THAT THERE WAS NOTHING WRONG WITH THE VEHICLE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED AND PROVIDED NO ASSISTANCE. THE FAILURE MILEAGE WAS 90,000....UPDATED 10/19/12 *BF UPDATED 10/25/12

DT*: THE CONTACT STATED WHILE DRIVING IN NORMAL CONDITIONS, THE TRANSMISSION LOCKED UP. THE VEHICLE WAS TAKEN TO THE DEALER SEVERAL TIMES FOR INSPECTION. THE DEALER REPLACED THE TRANSMISSION; HOWEVER, THE NEW TRANSMISSION HAS THE SAME PROBLEM.

TRANSMISSION MAKES A CLUNKING SOUND WHEN SHIFTING FROM 2ND TO 3RD GEAR. ALSO, INTERMITTNET SLIPPING OF TRANSMISSION WHEN STARTING TO MOVE FROM A FULL STOP. VEHICLE HESITATES BEFORE IT BEGINS TO MOVE. THIS OCCURED WITHIN THE 1ST 500 MILES AND CONTINES TO OCCUR TODAY.

AUTOMATIC TRANSMISSION WOULD INTERMITTENTLY HESITATE BEFORE CATCHING IN GEAR WHILE DRIVING. VEHICLE HAS BEEN TO THE DEALER ON TWO SEPARATED OCCASIONS AND THEY WERE UNABLE TO DUPLICATE THE PROBLEM. CONSUMER WAS CONCERNED THAT THIS VEHICLE MAYBE REAR ENDED. *AK THE TRUCK WAS ON AN INCLINE IN OVERDRIVE WITH MY FOOT ON THE BRAKE, LET OFF THE BRAKE AND GAVE IT GAS TO MERGE INTO TRAFFICS AND THE TRUCK WOULDN'T ACCELERATE. IT HESITATED UNTIL FELT LIKE A GEAR CAUGHT AND THEN INTO TRAFFIC INSTEAD OF GOING WHEN IT NEEDED TO GO. THE SECOND TIME WAS ALMOST THE SAME WAY. *BF

I PURCHASED MY 2004 GMC SIERRA 1500 4X4. I PUT IT IN 4 WHEEL DRIVE TO GO THROUGH SOME ICE AND IT MADE A VERY LOUD CLANK. NOT LONG AFTER THAT WHEN I PUT IT IN REVERSE OR DRIVE IT ALSO MADE THE SAME LOUD CLANK. IT DID NOT SOUND LIKE THAT WHEN I FIRST BOUGHT THE TRUCK. NOW THE TRUCK HAS TROUBLE GOING INTO 4 WHEEL DRIVE AND ALSO GETS HUNG IN REVERSE. IT HAS ALMOST CAUSED ME TO GET IN A BAD ACCIDENT. MY CRUISE CONTROL ALSO HAS HAVE 6 MALFUNCTIONS. I HAD THE DEALER FIX IT INITIALLY. I HAVE FIXED IT SUBSEQUENTLY DUE TO THE FACT THEY SAID IT WAS A BLOWN FUSE. THE 4 WHEEL DRIVE AND TRANSMISSION PROBLEMS WERE ADDRESSED 3 TIMES AND ALL THE DEALERS SAID NOTHING WAS WRONG. AN INDEPENDENT MECHANIC SAID THERE IS A DEFECT WITH MY TRANSMISSION AND TRANSFER CASE. THAT...

THE WINDSHIELD IS LEAKING WATER DOWN INTO THE ELECTRICAL SYSTEM. THE WIRING IS SHORTING OUT. ALSO, THE LINKAGE HAS FALLEN OUT. YOU CAN SMELL BURNT WIRING AND SMOKE. THE CONSUMER HAS CONTACTED THE DEALER SEVERAL TIMES. THE DEALER CONTINUOUSLY TOLD THE CONSUMER THAT THE GENTLEMAN WAS NOT THERE THAT SHE NEEDED TO SEE. CONSUMER HAD SOMEONE ELSE LOOK AT THE VEHICLE. AND WAS TOLD THE VIBRATION FROM DRIVING HAD JARRED THE THE PIN LOOSE. THE BLOWER, HEAT, AND THE TRANSMISSION FAILED. *AK

CONSUMER AND HIS WIFE WERE CLEANING THE VEHICLE. HUSBAND WAS OUTSIDE WASHING THE VEHICLE, WHILE THE WIFE WAS INSIDE THE VEHICLE, CLEANING. THE WIFE HAD THE KEY IN THE IGNITION, TURNED TO ACCESSORIES WHILE LISTENING TO THE RADIO, AND ACCIDENTALLY PUSHING THE SHIFTER DOWN WITH CAR BEING OFF AND VEHICLE MOVED BACKWARD, HITTING THE HUSBAND AND INJURING HIS KNEES.*AK THE CONSUMER ENTERED A FILE # OF 1-281746845. *TC

TRUCK VIBRATES AND MAKES NOISE BETWEEN 40 AND 50. SOUNDS LIKE BINDING. HAPPENS AS TRUCK IS SHIFTING IN AND OUT OF OVERDRIVE. DEALER HAS TRIED BUT CANNOT DUPLICATE CONDITION.*AK

THE TRANSMISSION HAS INTERMITTENT SHIFTING PROBLEMS, IT HESITATES AND BIG NOISE HAPPENS. DEALER HASN'T FOUND ANYTHING. ALSO TRUCK VIBRATES AT 40-50 MILES AN HR. VERY ANNOYING. THE DEALER SAYS ON GOING PROBLEM WITH NO SOLUTION. THINKING OF BUYING A FORD MOVING AHEAD. *NM

THE CENTER HUB OF THE WHEELS CONSTANTLY FALLS OFF. THE PLASTIC SCREWS THAT HOLD THE HUB ON THE WHEEL ARE NOT SECURING THE HUB PROPERLY. THE CONSUMER HAS LOST SIX OF THESE HUBS SINCE OWNING THE VEHICLE. *JB THE VEHICLE WOULD BUCK WHEN PUT INTO 4LOW AND SHIFTING INTO PARK OR NEUTRAL FROM REVERSE OR DRIVE. THE VEHICLE MADE A THUMPING NOISE WHEN MAKING LEFT TURNS AND THE CONSUMER COULD FEEL IT IN THE STEERING WHEEL. *NM

OUR SON-IN-LAW OWNS A 2004 GMC 4-DOOR PICKUP. IT HAS AUTOMATIC TRANSMISSION. OUR TWO-YEAR OLD GRANDSON WAS IN THE TRUCK WHILE HIS FATHER WAS CLEANING IT. THE KEY WAS IN THE ACCESSORY POSITION SO THEY COULD LISTEN TO THE RADIO. THE CHILD PULLED THE SHIFT LEVER OUT OF PARK AND THE TRUCK RAN AWAY DOWN AN INCLINE. BOTH DRIVER'S SIDE DOORS WERE SEPARATED FROM THE VEHICLE BY A TREE AND THE TRUCK CONTINUED UNTIL REAR-ENDING ANOTHER TREE. THE CHILD STAYED IN THE VEHICLE AND WAS UNHURT.*AK IN CHECKING THIS TRUCK, OUR 2003 TAHOE, AND OUR 2003 CHEVROLET PICKUP WE FIND THAT ALL OF THEM: 1. THE SHIFT LEVER IS LOCKED WHEN THE KEY IS IN THE LOCKED POSITION 2. THE SHIFT LEVER IS LOCKED WHEN IN THE "RUN" OR IGNITION POSITION AND REQUIRES THE BRAKE TO BE DEPRESSED PRIOR TO SHIFTING. 3. BUT IN THE "ACCESSORY" POSITION THE SHIFT IS...

TRANSMISSION WILL SLIP EVERY SO OFTEN, ALSO IT WILL MAKE A LOUD NOISE WHEN SHIFTING FROM 2ND TO 3RD. THIS HAPPENS ALOT BUT NOT EVERY TIME. THE FOUR WHEEL DRIVE MAKES A GRINDING NOISE AS YOU START MOVING AND CONTINUES FOR A GOOD DISTANCE (4 HIGH)*AK
