2003 CHEVROLET BLAZER Power Trainautomatic Transmission Problems

WE BOUGHT A 2003 CHEVY BLAZER IN JULY 2006 WITH 18,700 MILES. WHEN IN CRUISE CONTROL AT HIGHWAY SPEED, THE TRANSMISSION WILL DOWNSHIFT INTO 2ND GEAR INSTEAD OF 3RD GEAR TO MAINTAIN SPEED UP A SLIGHT INCLINE. THIS HAS HAPPENED NUMEROUS TIMES SINCE PURCHASE. *NM

I BROUGHT THE VEHICLE ON OCTOBER 04, 2005. I HAVE MANY PROBLEMS WITH THIS VEHICLE. I DON'T EVEN KNOW WHAT TO DO ANYMORE. I HAVE CONTACTED THE DEALERSHIP PLENTY OF TIMES BUT THEY ARE NO HELP AT ALL. THE VEHICLE HAS A TRANSMISSION PROBLEM. I HAVE TAKEN I IT TO THE MECHANIC BUT THEY HAVEN'T BEEN ANY HELP EITHER. I HAVE TRIED MANY TIMES TO GET THE DEALERSHIP TO HELP SINCE IT HASN'T EVEN BEEN A YEAR SINCE I BROUGHT IT BUT THEY JUST TOLD ME YOU BROUGHT IT SO IT'S YOUR PROBLEM. FOR THAT REASON I WANT TO CANCEL THE PURCHASE OF THE VEHICLE. *JB

2003 BLAZER LS 4X4, 29,000 MILES, AUTOMATIC TRANSMISSION. WE PURCHASED THIS CAR IN FEBRUARY 2004 WITH 21,000 MILES ON IT. IT CURRENTLY HAS 29,000 MILES. *AK CRUISE CONTROL AND TRANSMISSION SHIFT POINT WE HAVE OWNED THIS BLAZER FOR 5 MONTHS. IMMEDIATELY WE NOTICED THAT WHEN THE BLAZER HAS THE CRUISE CONTROL ENGAGED, FREQUENTLY WHEN TRAVELLING AT HIGHWAY SPEEDS, AND THE CRUISE CONTROL WANTS TO DOWNSHIFT TO THIRD GEAR IT WILL INSTEAD SHIFT INTO 2ND GEAR. THE DOWNSHIFT RED-LINES THE ENGINE TO 5000 RPM. IT HAS DOWNSHIFTED FROM 4TH GEAR TO 2ND GEAR AROUND TWO DOZEN TIMES IN 7,000 MILES. AND RECENTLY IT HAS DOWNSHIFTED TO 2ND GEAR WHEN THE BLAZER WAS NOT ON CRUISE CONTROL -- JUST WHEN THE DRIVER IS DRIVING UP A SLIGHT INCLINE. SOON AFTER PURCHASE OF THE CAR WE RETURNED IT TO CHAMPION CHEVROLET IN RENO, NEVADA, TO HAVE THEM FIX THIS PROBLEM. THEY COULD NOT...

INTERMITTENTLY, WHILE PARKING THE VEHICLE ON A SLIGHT INCLINE, THE VEHICLE ENGAGED FROM PARK TO REVERSE AND SURGES. THE DEALER HAS INSPECTED AND FOUND NOTHING WRONG. THE OWNER WAS SCHEDULED TO RECEIVE TWO HOURS DRIVING CLASS. *NLM

CONSUMER HAD EXPERIENCED LOUD THUMPING FROM THE ENGINE COMPARTMENT. THERE WERE TIMES WHEN TRANSMISSION GOT STUCK IN ONE GEAR FOR AN EXTENDED AMOUNT OF TIME. VEHICLE WAS TAKEN TO THE DEALER FOUR TIMES FOR TRANSMISSION PROBLEMS. ALSO, FUEL GAUGE WAS NOT FUNCTIONING PROPERLY. WHEN GAS WAS IN THE TANK IT COULD REGISTER FULL ONE MINUTE AND HALF FULL THE NEXT MINUTE WITHOUT MOVING THE VEHICLE. MANUFACTURER AND THE DEALER HAD BEEN NOTIFIED.*AK

WHILE DRIVING AT 55 MPH , VEHICLE WOULD NOT ACCELERATE AND IT FELT LIKE IT WAS IN NEUTRAL GEAR. VEHICLE ALMOST GOT HIT BY ONCOMING TRAFFIC. A SENSOR IN ENGINE CAUSED TRANSMISSION TO GO OUT OF DRIVE GEAR. *AK
