TRAVELING HOME FROM WORK ON THE INTERSTATE AT REGULATED SPEED (65MPH). AS I STARTED TO ACCELERATE TO MAINTAIN SPEED GINGO UP A HILL, THE MESSAGE "TRANSMISSION HOT" CAME ON THE IN-DASH DISPLAY AND ENGINE BEGAN REVVING AS IF NOT IN GEAR. I COULD NOT ACCELERATE AND HAD TO TURN ON FLASHERS AND MERGE TO SAFETY LANE ON RIGHT. I CONTINUED TO SLOW DOWN UNTIL I COULD ENGAGE THE TRANSMISSION AGAIN AT AROUND 30 MPH IN 3RD GEAR. AS SOON AS I STARTED TO ACCELERATE PAST 35-40 MPH, THE TRANSMISSION SLIPPED AGAIN AND WOULD NOT ENGAGE ANY GEAR. THIS HAPPENED ALL THE WAY HOME SO WHAT SHOULD HAVE BEEN A 20 MINUTE DRIVE TURNED INTO AN HOUR. I COULDN'T GET ABOVE 35-45 MPH WITHOUT THIS HAPPENING EACH TIME WHICH MADE NAVIGATING THE HILLS OF NORTHERN VA IN THE RAIN NOT VERY FUN FOR ME NOR THE HUNDREDS OF FRUSTRATED DRIVERS BEHIND AND BESIDE ME. AS I PULLED INTO THE DRIVEWAY AND PARKED, I COULD NOTICE A 'BURNT AND SOUR" SMELL...MOST LIKELY TRANSMISSION FLUID. I DIDN'T SEE ANY LEAKS OR DRIPS BUT THE ENGINE WAS EXTREMELY HOT AS WAS TRANSMISSION AND TRANSFER CASE. THIS HAS BEEN HAPPENING OFF AND ON FOR A FEW MONTHS NOW BUT IN VERY LIMITED OCCASIONS AND NEVER FOR MORE THAN 10-20 SECONDS SO I HAVEN'T CONTACTED A SERVICE STATION BUT WILL DEFINITELY DO SO THIS WEEKEND AS I AM UNABLE TO LEAVE WORK DURING THE WEEK FOR THIS ISSUE. *TR

Vehicle Speed Control
SPEEDOMETER ON MY 2005 AVALANCHE STARTED TO ACT ERRATIC WHILE DRIVING. IT GIVES FALSE SPEED INDICATION FOR EXAMPLE DRIVING ON THE FREEWAY AT 6-MPH IT WILL JUST DROP TO 30MPH EVEN THOUGH THE VEHICLE SPEED HAS NOT CHANGED. MY CONCERN IS THE CREEPING EFFECT OF THE TRUCK AND STILL INDICATING A SLOWER SPEED. *TR
ON CERTAIN TRUCKS EQUIPPED WITH AN 8.1L V8 (RPO L8-VIN G) ENGINE HAVE A CONDITION IN WHICH THE ENGINE FUEL RAIL PULSE DAMPER RETAINER CLIP MAY FRACTURE RESULTING IN INADEQUATE RETENTION OF THE DAMPER.
Consequence & remedy
Consequence: IF THE DAMPER COMES LOOSE, A FUEL LEAK MAY RESULT. FUEL LEAKAGE, IN THE PRESENCE OF AN IGNITION SOURCE, COULD RESULT IN A FIRE.
