WHILE DRIVING, ESPECIALLY WHEN THE TEMP IS UNDER 40 DEGREES. I RANDOMLY GET ERROR WITH TRACTION CONTROL OFF AND REDUCED ENGINE POWER. I HAVE TROUBLE ACCELERATING AND KEEPING SPEED. WHICH HAS BEEN VERY DANGEROUS TO GET TO A SAFE SPOT ON THE EXPRESSWAY TO PULL OFF, WHEN MY SPEED SUDDENLY CHANGES. THIS HAS BEEN HAPPENING FOR THE LAST 3 YEARS DURING THE COLD MONTHS AND I HAVE GOT ITEMS CLEANED AND SENSORS CHANGED TO NO END.

MY TRANSMISSION/ TRANSAXLE HAS BEEN REBUILT 3 TIMES. WHAT I HAVE RESEARCHED AT THIS TIME IS THAT THE BASE MODEL 4T65E TRANSAXLE DOESN'T REALLY DIFFER IN THE HARD PARTS FOR THE 4T65E-HD THATS IN MY PONTIAC GRAND PRIX GXP. BAD JERKING AND SLIPPING FROM TAKE OFF OR ACCELERATING IS MY PROBLEM. JUST THIS YEAR MY CAR COULDN'T ACCELERATE OVER 40MPH BECAUSE OF THIS PROBLEM. ANYONE I TALK TO WHO HAS THE SAME MOTOR COMBINATION OF THE LS4 MOTOR WITH THE 4T65E-HD TRANAXLE HAS BEEN DEALING WITH THE SAME SIMILAR ISSUES. WETHER IT BE THE IMPALA SS 2006-2009, MONTE CARLO SS 2006-2007, BUICK LACROSSE SUPER 2008-2009, OR THE PONTIAC GRAND PRIX GXP 2005-2008. THE FRONT WHEEL DRIVE COMBINATION WITH THE POWER IN THE 303 HP MOTOR IS TOO MUCH FOR THE 4T65E-HP TRANSMISSION. I'VE FOUND A WEBSITE THAT CLAIMS THEY HAVE SOLVED THE FLAWS WITH THIS PROBLEM. THE WEBSITE EXPLAINS IN DETAIL WHAT PARTS THEY USE AND HOW IT CAN SUPPORT THE POWER OF THE LS4 MOTOR. PERSONALLY I FEEL LIKE I SHOULD NOT PAY FOR SOMETHING THAT SHOULD'VE BEEN A RECALL CLOSE TO A DECADE AGO.

AFTER TRAVELING ABOUT 150 MILES FROM MACON, GA, IN THE MORNING OF THE 16TH, THE CAR SHUT DOWN ON I-75 IN HEAVY TRAFFIC GOING 75 MPH IN THE PASSING LANE. WE HAD NO ENGINE POWER, POWER STEERING OR BRAKES, BUT MANAGED TO COAST TO THE SHOULDER. I WAS ABLE TO RESTART THE CAR AFTER A FEW MINUTES ONLY TO HAVE IT STALL OUT AFTER 10 OR 15 MILES. THE ONLY WARNING WAS 2 CHIMES FROM THE CAR BEFORE TOTAL SHUT DOWN. WE DID HAVE FLASHER LIGHTS AND WERE ABLE TO RESTART THE CAR EACH TIME. THIS HAPPENED ABOUT 6 OR 8 TIMES. WE STOPPED AT SEVERAL AUTO PARTS PLACES TO SEE IF WE COULD FIND OUT WHAT THE PROBLEM WAS, BUT NO LUCK. WE WERE ABLE TO GET TO A CHEVROLET DEALER IN ASHBURN, GA (PARKER CHEVROLET). THEY WERE NOT ABLE TO DIAGNOSE THE PROBLEM, OR DIDN'T WANT TO DEAL WITH IT. POOR SERVICE! THEY SAID EVERYTHING WAS OKAY! JUST 2 MILES FROM THE DEALERSHIP, IT STALLED AGAIN. WE MANAGED TO GET TO GAINESVILLE, FL WHERE THE CLOSEST CHEVROLET DEALER WAS LOCATED. WE TALKED TO [XXX] FROM GAINESVILLE AUTOMOTIVE CHEVROLET WHO WAS A CALMING VOICE AFTER OUR EXPERIENCE. SHE GAVE US A HOTEL RECOMMENDATION FOR THE NIGHT AND SAID TO BRING THE CAR IN AT 7 AM THE FOLLOWING MORNING. SHE WAS GREAT, AND SO WAS THE ENTIRE STAFF! THEY GOT RIGHT TO WORK ON THE CAR THE NEXT DAY AT 7 AM. AFTER ABOUT AT HOUR, THE SERVICE MANAGER INFORMED US THEY FOUND THE PROBLEM, BUT IT WOULD REQUIRE A NEW COMPUTER AT A COST OF $940 AND COULD BE BACK ON THE ROAD BY NOON. WE WERE BACK ON THE ROAD BY 12:30. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

TRACTION CONTROL / ABS BRAKES FEEL LIKE THEY WELL NOT STOP VEHICLE/ WHEN ABS AND TRACTION CONTROL LIGHTS COME ON WHICH IS PROBABLY 90% OF THE TIME . ABOUT 2 MONTHS AGO I HAD THE ROTORS AND PADS REPLACED , I THOUGHT THIS WOULD CURE THE PROBLEM ONLY TO MAKE MATTERS WORSE. THANK YOU *TR

THE FIRST INCIDENT HAPPENED WHILE DRIVING THE CAR IT JUST STOPPED AFTER I MADE A TURN AND READ DISABLED DUE TO ELECTRONIC THROTTLE BODY. AFTER A FEW MOMENTS IT JUST RESTARTED. THE LIGHTS AND EVERYTHING STILL WORK THE CAR WILL JUST NOT CRANK BACK UP UNTIL AFTER A FEW MOMENTS. THIS HAS HAPPENED APPROXIMATELY 7 TIMES. I TAKE THE KEY OUT AND WAIT FOR ABOUT 3 TO 4 MINUTES AND THEN THE CAR WILL START BACK UP LIKE NOTHING HAS HAPPENED. I HAVE TAKEN IT TO A FEW MECHANICS, AND THEY WERE NOT ABLE TO PULL ANY CODES, AND BASICALLY TOLD ME TO TAKE IT TO THE DEALER. NOW THAT I HAVE TAKEN IT TO THE DEALER, THEY HAVE HAD THE CAR SINCE MONDAY TODAY IS FRIDAY AND THEY ARE UNABLE TO DETERMINE WHAT THE PROBLEM IS BECAUSE THE CODES DON'T PULL UP AND THE CAR HASN'T DONE IT SINCE THEY HAVE HAD IT. *TR
