Pontiac Grand Prix Power Train Automatic Transmission Safety Report | Jan 18, 2009
Reported on Jan 18, 2009
| MY CAR AT ONLY 54K MILES, TRANSMISSION FAILED, CAUSING TO LOOSE POWER IN TRAFFIC. I HAD THE TRANSMISSION REBUILT ($2400), 8 MONTHS LATER IT FAILED AGAIN ($1200), 2 MONTHS LATER, FAILED AGAIN ($0-WARRANTY). MECHANIC FINALLY FIGURED OUT IT WAS SOME PRESSURE RELIEVE VALVE ON THE TRANSMISSION, CAUSING PRESSURE TO BUILD UP, CAUSING THE TORQUE CONVERTER TO EXPLODE, SENDING DEBRIS THROUGHOUT THE TRANSMISSION. I DID NOT GO TO DEALER AS CAR FOR THAT MODEL YEAR WAS OUT OF WARRANTY, BUT WENT TO TRANSMISSION SHOP WHO HAS BEEN IN BUSINESS FOR ABOUT 30 YEARS. I WROTE TO GM, BUT GOT NO MONETARY SATISFACTION. MANY PEOPLE I'VE READ ABOUT ONLINE WITH THIS TYPE OF TRANSMISSION HAVE HAD SIMILAR PROBLEMS. I'VE NEVER HAD TRANSMISSION TROUBLE IN ALL THE CARS I'VE EVER OWNED. IT WOULD SEEM THERE IS A DEFECT IN THIS MODEL, AND WOULD LIKE TO RECOUP THE MONEY SPENT ON THIS ISSUE. IT SEEMS IT'S ON GM MODELS WITH A V8 FRONT WHEEL DRIVE TRANSMISSION. LIKE THE PONTIAC GRAND PRIX GXP, AND MONTE CARLO SS, BUICK LUCERNE V8. *TR | |
