2002 Chevrolet Tahoe Power Train

TRANSMISSION FAILS TO FUNCTION APPROPRIATELY WHEN GOING FROM A STOPPED POSITION TO FORWARD OR REVERSE. IN REVERSE POSITION, LOUD GRINDING NOISE IS HEARD. IN FORWARD, VEHICLE HESITATES BEFORE FINALLY MOVING FORWARD. THIS HAS BEEN TO DEALER FOR REPAIR 3 TIMES. FIRST REPAIR REVEALED FRONT THRUST SHIM WITH TOO MUCH END PLAY; TRANSMISSION ASSEMBLY WAS REBUILT (MANUFACTURER REFUSED TO REPLACE), THRUST WASHER REPLACED AND TRANSMISSION OVERHAULED. TWO RETURN VISITS FOR SAME PROBLEM AND DEALER SAYS THEY CANNOT RECREATE AND HAVE FOUND NO PROBLEMS. *NLM

I BEGAN NOTICING THAT MY TAHOE WAS NOT FUNCTIONING CORRECTLY IN LATE NOVEMBER OR EARLY DECEMBER 2001. OCCASIONALLY, WHEN I SHIFTED THE CAR FROM PARK TO REVERSE AND PRESSED ON THE GAS THE ENGINE WOULD REV, BUT THE TRUCK WOULD NOT MOVE. ADDITIONALLY, OCCASIONALLY AFTER STOPPING AT A STOP SIGN/LIGHT THE ENGINE WOULD REV AND THE TRUCK WOULD NOT MOVE. I TOOK THE TRUCK TO JOHN THORNTON CHEVROLET TO BE LOOKED AT. THEY TOLD ME THAT THERE WAS A DEFECTIVE VALVE BODY IN THE TRANSMISSION. THEY EXPLAINED THAT THE VALVE BODY HAD BURS LEFT ON IT AT THE TIME IT WAS MANUFACTURED AND THAT THE BURS SHOULD HAVE BEEN REMOVED. THE BURS WERE FALLING OFF OF THE VALVE BODY AND INTO THE TRANSMISSION FLUID CAUSING A BLOCKAGE WHICH CAUSED THE PROBLEM. THEY REPLACED THE VALVE BODY. APPROXIMATLEY 3 WEEKS AGO I BEGAN HAVING THE SAME PROBLEM. I TOOK THE TRUCK BACK TO SAME DEALERSHIP AND THEY TOLD ME THAT IT, AGAIN, WAS A DEFECTIVE VALVE BODY AND THEY REPLACED IT. I CALLED CHEVROLET TO INQUIRE ABOUT THIS PROBLEM. THEY STATED THAT THEY WERE NOT AWARE OF IT, BUT WOULD LOOK INTO IT. TODAY, JULY 30, 2002, I HAD THE SAME PROBLEM OCCUR. I CALLED CHEVROLET AGAIN AND THEY TOLD ME TO CONTACT A DEALERSHIP FOR AN EVALUATION. I HAVE CONTACTED THE DEALERSHIP FOR AN APPOINTMENT, HOWEVER, THE DEALERSHIP STATED THAT THEY ARE ONLY ABLE TO FIX WHAT CHEVROLET TELLS THEM THEY CAN FIX WHEN THE VEHICLE IS UNDER WARRENTY. SO FAR THIS HAS ONLY OCCURRED WHEN I AM TRYING TO GO FROM A STOP TO START, HOWEVER, I AM CONCERNED THAT THE TRANSMISSION WILL MALFUNCTION WHEN I AM DRIVING AT HIGHWAY SPEED. I APPRECIATE YOUR CONCERN AND I HOPE THAT YOU WILL BE ABLE TO BRING THIS TO RESOLUTION SINCE I HAVE NOT BEEN ABLE TO IN WORKING WITH CHEVROLET AND THE DEALERSHIP.*AK
