2000 GMC Sierra Powertrain & Transmission Problems

THE NP246 TRANSFER CASE OIL PUMP PLATE WEARS A HOLE INTO THE CASE, CAUSING IT TO LEAK. THERE IS A SAVER PLATE THAT CAN BE INSTALLED THAT PREVENTS THIS PROBLEM.

ON FEBRUARY 15, 2012 AT APPROXIMATELY 11:00AM, DRIVING DOWN A TWO LANE PAVED HIGHWAY, THE CROSS PIN IN THE REAR DIFFERENTIAL GEAR HOUSING FAILED AND PARTS OF IT FELL INTO THE GEARS CAUSING THE REAR TIRES TO LOCK UP AND THE VEHICLE TO SKID OUT OF CONTROL INTO THE ONCOMING TRAFFIC LANE. LUCKILY, ONCOMING TRAFFIC WAS ABLE TO STOP IN TIME AVOIDING AN ACCIDENT. THIS WAS VERIFIED BY AMERICAN COLLISION IN RUTLAND, VT AS THE CAUSE OF THE FAILURE.

TL* THE CONTACT OWNS A 2000 GMC SIERRA 1500. WHILE EXITING A RAMP AT 35 MPH HE LOST POWER STEERING. HE WAS ABLE TO SAFELY DRIVE THE VEHICLE HOME. UPON VEHICLE INSPECTION HE NOTICED THAT THE POWER STEERING PUMP SHAFT FRACTURED. HE REPAIRED THE VEHICLE HIMSELF. HE WAS ADVISED BY THE MANUFACTURER THAT HIS VEHICLE IDENTIFICATION NUMBER WAS EXCLUDED FROM RECALL# 05V005000 (POWER TRAIN:DRIVE LINE:DRIVE SHAFT). THE FAILURE MILEAGE WAS 102,000. UPDATED 12/10/09. *LJ UPDATED 12/10/09.*JB

DT*: THE CONTACT STATED WHILE DRIVING AT VARIOUS SPEEDS THE VEHICLE INTERMITTENTLY FAILS TO SHIFT INTO THIRD AND FOURTH GEARS. WHEN THE SHIFTER FAILS THE DIGITAL GAUGES FAIL TO ILLUMINATE. THE VEHICLE SHIFTS NORMALLY AFTER A SHORT PERIOD OF TIME. UPON INSPECTION THE INDEPENDENT REPAIR SHOP WAS UNABLE TO DETERMINE THE CAUSE OF THE FAILURE.

JANUARY 27, 2005, MY TRUCK WAS TAKEN TO DEALERSHIP D/T LOUD METAL GRINDING IN THE LEFT FRONT WHEEL(DRIVER'S SIDE). THE BRAKES AND ROTORS WERE REPLACED. THE SOUND CONTINUED AND WAS TAKEN BACK TO DEALERSHIP FEBRUARY 2, 2005 AND THE BEARING WAS "CLEANED OUT". MAY 7, 2005 WHILE DRIVING ON INTERSTATE THE LEFT FRONT WHEEL FELT LIKE I HIT SOMETHING. WHEN I GOT OFF THE INTERSTATE THERE WAS A BURNING SMELL. ROUNDING A CURVE AT 25 MPH THE HUB AND THEN THE AXEL BROKE. THE TRUCK WAS NOT DRIVABLE AND WAS TOWED BY AAA TO THE DEALERSHIP. IT WAS REPAIRED AND I WAS TOLD IT WAS D/T THE AFTER-MARKET WHEELS.

TRUCK DRIVE TRAIN INTERMITTENTLY MAKES CLUNK NOISE WHEN I FIRST START OFF FROM A STOP. WHEN I STOP AT A RED LIGHT IT FEELS LIKE SOMEONE JUST HIT ME FROM BEHIND GOING FROM FIRST INTO SECOND GEAR. IT STARTED AT ABOUT 88000 MILES / 4 YEARS AGO AND HAS BEEN GETTING PROGRESSIVELY WORSE. THE PROBLEM SEEMS TO BE ELECTRICAL OF SORTS. WHEN THE TRUCK STARTS ACTING UP WITH THIS PROBLEM I USUALLY PULL OFF TO THE SIDE OF THE ROAD & TURN OFF THE IGNITION...WAIT 20-30 SECONDS & RESTART THE IGNITION...98% OF THE TIME THE PROBLEM GOES AWAY. THIS IS A RECURRING PROBLEM & THE DEALERSHIPS GIVE ME NOTHING BUT THE RUNAROUND. THE TRUCK SERVES ME WELL WITH 238000 MILES ON HER BUT I MOST DEFIANTLY WOULD LIKE TO FIND THE CURE & FIX THIS PROBLEM. *TR

DT: THE CONTACT STATED THE TRANSMISSION FAILED WHILE DRIVING. THE VEHICLE WOULD NOT GO INTO REVERSE. AFTER GETTING THE VEHICLE HOME HE HAD IT TOWED TO A TRANSMISSION SHOP. THEY FOUND THERE WAS A CRACK IN AN INTERNAL HUB. THIS CAUSED A LOSS OF OIL PRESSURE, AND LUBRICATION. THEY REPLACED ALL DAMAGED PARTS. THERE HAVE BEEN NO PROBLEMS SINCE. *AK

THE PUMP DRIVESHAFT FRACTURED, CAUSING IMMEDIATE LOSS OF POWER STEERING AND POWER BRAKES. WHILE ON THE INTERNET, OWNER DISCOVERED THAT THE SAME YEAR/MAKE AND MODEL WAS BEING RECALLED FOR THIS DEFECT. OWNER LATER CONTACTED THE MANUFACTURER. HOWEVER THIS VEHICLE WAS NOT INCLUDED IN THE RECALL DUE TO THE VIN. *AK

HEARD A WHINING NOISE AND WOULDN'T SHIFT PROPERLY. IT WOULD ONLY MOVE VERY SLOWLY FORWARD AND WOULD NOT GO INTO REVERSE. *JB

TRUCK DRIVE TRAIN MAKES CLUNK NOISE WHEN I FIRST START OFF FROM A STOP, ALSO IN REVERSE. WHEN I STOP AT A RED LIGHT IT FEELS LIKE SOMEONE JUST HIT ME FROM BEHIND. IT STARTED AT ABOUT 39000 MILES AND HAS BEEN GETTING PROGRESSIVELY WORSE AND NOW IT HAS WORN OUT THE BUSHING IN THE TAIL SHAFT OF THE TRANSMISSION ,WOW $32000 DOLLARS FOR THIS TRUCK AND NOTHING BUT PROBLEMS .I AM TRULY SCARED OF THIS TRUCK PLEASE HELP. *JB

TRANSMISSION FAILED. NO REVERSE. REACTION SHELL GEAR TEETH STRIPPED OUT. COMMON PROBLEM WITH 4L60E TRANSMISSIONS. ONLY 52000 MILES. WENT OUT WITH NO WARNING.*AK

WHILE DRIVING VEHICLE WILL NOT GO INTO OVERDRIVE OR GO INTO REVERSE. DEALER NOTIFIED.*AK

2000 2WD SIERRA - SUN GEAR SHELL DEFECTIVE FROM MFG (KNOWN PROBLEM) (1) TOTAL TRANSIMISSION FAILURE - REBUILD. (2) TOTAL TRANSMISSION FAILURE - REBUILD. *AK

CONSUMER WAS TRAVELING ABOUT 15MPH ON HIGHWAY AND HEARD A NOISE WHEN AUTOMATIC TRANSMISSION CHANGED FROM FIRST TO SECOND GEAR. ALSO, THERE WAS VIBRATION WHEN SHE TURNED LEFT TO RIGHT. DEALERSHIP WAS AWARE OF PROBLEM.*AK

WHEN THE TRUCK IS STOPPED, YOU PRESS THE ACCELERATOR AND THE ENGINE WILL REV UP, BUT THE TRUCK WILL NOT PROCEED FORWARD. SECONDS LATER, YOU WILL HEAR THIS LOUD "THUNK" IN THE REAREND OF THE VEHICLE AND THE TRUCK WILL VIRTUELY JUMP FORWARD CAUSING YOU TO ALMOST HIT A CAR IN FRONT OF YOU. THE SAME OCCURS WHEN BRINGING THE VEHICLE TO A STOP.*AK

THE TRANSMISSION SLIPPED MULTIPLE TIMES AND ACCELERATED VERY SLOWLY. DEALER NOTIFIED.*JB

ON 12/13/99 WHEN SLOWING DOWN TO MAKE A LEFT TURN, THE TOURQUE CONVERTER LOCKED UP AND STALLED THE TRUCK IN MIDDLE OF TRAFFIC WHILE CROSSING THE LEFT LANE. WITH DIFFICULTY, TRUNED THE WHEEL BACK TO THE RIGHT AND PULL OFF THE ROAD AND SHIFTED INTO PARK AND RESTARTED THE TRUCK. LUCKLY THERE WAS VERY LITTLE ON COMING TRAFFIC. ON 2/11/00 WHILE COMING INTO A ROLLING RIGHT HAND TURN AND GOING ABOUT 15 MPH, I STARTED TO BRAKE AND THE TOURQUE CONVERTED AGAIN LOCKED UP AND THE ENGINE STALLED. AGAIN WITH DIFFICULTY I WAS ABLE TO STEER INTO THE CORNER AND MAKE THE CORNER. AS THE TRUCK WAS FREE ROLLING IT JUST STARTED ITSELF AND IT CONTIUNED ON, ALMOST CRACHED INTO TWO CARS WAITING AT THE STOP SIGN. IF MY WIFE WAS DRIVING THERE WOULD HAVE BEEN A COLLISION. IN OCTOBER WHEN WAITING FOR A TRAFFIC LIGHT TO CHANGE, I ACCELLERATED AND TRUCK DIDN'T MOVE. I STEPPED ON THE BRAKE SHIFTED TO PARK AND THEN BACK TO DRIVE AND IT FINALLY WENT INTO GEAR AND MOVED. HAVE BEEN BACK TO THE DEALER TWICE WITH TOURQUE CONVERTER CONCERNS WITH NO SOLUTIONS. GM HAS A TRANSMISSION PROBLEM WITH THERE 4L60E TRANSMISSIONS. MY 1998 GMC JIMMY HAS BEEN REPLACED AT 19000 MILES. AM VERY WORRIED THAT THIS WILL HAPPEN AT ANY TIME WHEN NOT READY AND AN ACCEDENT WILL HAPPEN. *AK
