DT: THE CONTACT RECEIVED NHTSA RECALL 05V379000 CONCERNING THE ANTI -LOCK BRAKE SYSTEM. HE TOOK THE VEHICLE TO THE DEALERSHIP, AND THEY PERFORMED THE RECALL REPAIRS. THE ABS LIGHT WAS STILL ON, AND THE ABS DID NOT WORK. WHILE DRIVING FOR SHORT PERIODS OF TIME THE CONSUMER EXPERIENCED BRAKE FAILURE. THIS RESULTED IN EXTENDED STOPPING DISTANCE. HE CONTACTED THE DEALERSHIP AND MANUFACTURER, BUT THE PROBLEM WAS NOT COVERED BY THE RECALL.*AK THE CONSUMER HAD DIFFICULTY SHIFTING INTO 3RD GEAR. UPDATED 12/07/05. *JB

DT: THE CONTACT STATED THE TRANSMISSION FAILED WHILE DRIVING. THE VEHICLE WOULD NOT GO INTO REVERSE. AFTER GETTING THE VEHICLE HOME HE HAD IT TOWED TO A TRANSMISSION SHOP.

ON 12/13/99 WHEN SLOWING DOWN TO MAKE A LEFT TURN, THE TOURQUE CONVERTER LOCKED UP AND STALLED THE TRUCK IN MIDDLE OF TRAFFIC WHILE CROSSING THE LEFT LANE. WITH DIFFICULTY, TRUNED THE WHEEL BACK TO THE RIGHT AND PULL OFF THE ROAD AND SHIFTED INTO PARK AND RESTARTED THE TRUCK. LUCKLY THERE WAS VERY LITTLE ON COMING TRAFFIC. ON 2/11/00 WHILE COMING INTO A ROLLING RIGHT HAND TURN AND GOING ABOUT 15 MPH, I STARTED TO BRAKE AND THE TOURQUE CONVERTED AGAIN LOCKED UP AND THE ENGINE STALLED. AGAIN WITH DIFFICULTY I WAS ABLE TO STEER INTO THE CORNER AND MAKE THE CORNER. AS THE TRUCK WAS FREE ROLLING IT JUST STARTED ITSELF AND IT CONTIUNED ON, ALMOST CRACHED INTO TWO CARS WAITING AT THE STOP SIGN. IF MY WIFE WAS DRIVING THERE WOULD HAVE BEEN A COLLISION. IN OCTOBER WHEN WAITING FOR A TRAFFIC LIGHT TO CHANGE, I ACCELLERATED...
