[MAHHHK]

04 SIERRA 2500 HD 6.0 4L80E MANUEL TRANSFER CASE SHIFT; NO FORWARD/REVERSE

AT LOW SPEED; BRAKED AT INTERSECTION; HEARD A RATLLE; FELT LIKE I LOST DRIVE...STOPPED; APPLIED ACCTELLERATOR;
A LITTLE RATTLE AND DRIVE FHAD FAILED; REVERSE FAILED AS WELL;
IN PARK THE PIN BEGAN TO STRIP; BACK TO NUETRAL I SHIFTED AND TRIED ALL TRANSFER CASE POSTIONS; NO GO;
IN 2WD I HEARD TRANNY SHIFT FROM FORWARD TO REVERSE A FEW TIMES; NO GO.
LINKAGE ALL IN PLACE AT THAT POINT - SNOW/RAIN HERE SO I'LL LOOK CLOSER TOMORROW.
SINCE THE TRANNY IS SHIFTING FORWARD TO REVERSE ETC. I'M THINKING THE TRANSFER CASE CHAIN DISCONNECTED AND DROPPED...
JUST WONDERING ONE OF YOU GUYS HAVE HAD THE SAME FUN.
TY,
