2004 Pontiac Bonneville

IN JAN 2009 @ 72K MILES ON THE CAR SERVICE ENGINE LIGHT COMES ON AND SHORTLY AFTER THE TRANS. WOULD BANG INTO GEAR. PER GM DEALER IT HAD CODES P0756 AND P2763 CALLING FOR REPLACEMENT OF SHIFT SOLENOID. IN SEPT. 2010 @ 108K MILES THE EXACT SAME ISSUE AND CODE, REPLACED THE SAME PART. NOW IN FEB 2012 @137K MILES AGAIN THE SAME EXACT ISSUE AND CODES, BUT THIS TIME THEY ARE SAYING TO REPLACE THE TRANS. THE FIRST 2 TIMES I WENT TO THE SAME DEALER, THIS TIME I WENT TO ANOTHER. ISSUE I HAVE IS IT SOUNDS LIKE THIS SHOULD HAVE BEEN REPLACED AT 72K WHILE UNDER AN EXTENDED 5 YEAR, 100K MILE WARRANTY. GM IS UNWILLING TO ADMIT ANY FAULT OR DEFECT. I FEEL THAT THIS PART FAILING 3X WITHIN 65K MILES IS AN ISSUE AND SHOULD BE INVESTIGATED. ALSO LOOKING THRU SOME OF THE HISTORY I SEE THIS SAME TYPE OF ISSUE IN THE 2003 CARS. *TR

CAR STARTED SHIFTING HARD FROM 2ND TO 3RD GEAR-- TOOK IT IN TO A PONTIAC DEALER AND THEY STATED IT WAS THE PRESSURE REGULATOR SOLENOID WHICH IS THE SAME ISSUE THEY WERE HAVING WITH THE 2003 MODELS THAT HAD NUMEROUS SERVICE BULLETINS ON. I CALLED GM AND THEY AGREED TO COVER THE CHARGES TO FIX IT; HOWEVER, WHEN I HAD IT FIXED AND $1,100 LATER-- THEY SAID THEY WEREN'T GOING TO COVER IT BECAUSE IT WASN'T A 2003 MODEL. *TR
