AS I WAS TAKING A FAMILY TRIP, I WAS TRAVELING THROUGH SOME STEEPER GRADES WHEN THE VEHICLE RPMS WERE REGISTERING VERY HIGH AND WOULD NOT SHIFT TO LOWER GEARS EVEN WHEN MY TRAVEL SPEED SLOWED DOWN. ON MY DISPLAY A WARNING CAME ON SAYING TO IDLE THE VEHICLE TRANSMISSION HOTќ I THEN PULLED OVER IN A VERY BUSY ROAD AND LET THE VEHICLE IDLE FOR 10 MIN IT THEN SHUT OFF BUT HAD VERY WEIRD DRIVING CHARACTERISTIC THE REST OF THE WAY. THIS INCLUDED WHEN SHIFTING FROM SECOND GEAR TO THIRD IT FELT LIKE THE CLUTCH WOULD POP AND JERK THE VEHICLE WHEN IT DID SHIFT. THANKFULLY AS WE GOT CLOSER TO A TOWN THE VEHICLE ENGINE LIGHT CAME ON AND WE IMMEDIATELY CONTACT ONSTAR AND THEY GAVE US THE CODES ALL RELATING TO THE VEHICLE WAVE PLATE FAILURE. I THEN HAD TO TAKE IT TO A DEALER OUT IN THE TOWN WE WERE VISITING AT THE TIME WHICH WAS A MAJOR HEADACHE. THIS WAS VERY DISAPPOINTING CONSIDERING THE VEHICLE BARLEY HAD OVER 50,000 MILES AND GMC IS SUPPOSED TO BE A UPGRADE FOR GM. SHAME ON THEM FOR NOT RECALLING ALL 2007-2009 MODELS TO REPAIR THIS ISSUE. NEEDLESS TO SAY GM DID OFFER TO HELP WITH REPAIR COST ONLY CAUSE THEY KNOW IT'S A KNOW ISSUE WHICH I APPRECIATE BUT THE FACT IS WITH THAT LOW OF MILES ON THE VEHICLE THAT SHOULD HAVE NEVER HAPPENED IN THE FIRST PLACE. *TR
