POWER TRAIN:DRIVELINE
TRUCK DRIVE TRAIN INTERMITTENTLY MAKES CLUNK NOISE WHEN I FIRST START OFF FROM A STOP. WHEN I STOP AT A RED LIGHT IT FEELS LIKE SOMEONE JUST HIT ME FROM BEHIND GOING FROM FIRST INTO SECOND GEAR. IT STARTED AT ABOUT 88000 MILES / 4 YEARS AGO AND HAS BEEN GETTING PROGRESSIVELY WORSE. THE PROBLEM SEEMS TO BE ELECTRICAL OF SORTS. WHEN THE TRUCK STARTS ACTING UP WITH THIS PROBLEM I USUALLY PULL OFF TO THE SIDE OF THE ROAD & TURN OFF THE IGNITION...WAIT 20-30 SECONDS & RESTART THE IGNITION...98% OF THE TIME THE PROBLEM GOES AWAY. THIS IS A RECURRING PROBLEM & THE DEALERSHIPS GIVE ME NOTHING BUT THE RUNAROUND. THE TRUCK SERVES ME WELL WITH 238000 MILES ON HER BUT I MOST DEFIANTLY WOULD LIKE TO FIND THE CURE & FIX THIS PROBLEM. *TR
