1996 GMC Sierra Transmission Problems

WHILE TOWING TRAILER WITH 2 QUADS (4 WHEELERS) ON EXPRESSWAY WITH A GROUP OF CO-WORKERS, I WAS ATTEMPTING TO PASS ANOTHER VEHICLE WHEN MY TRUCK WOULD NOT SHIFT INTO PASSING GEAR. IT MADE A LOUD "REVING" NOISE AND BEGAN RAPIDLY DECREASING IN SPEED. I PULLED OFF THE EXPRESSWAY BRINGING THE VEHICLE TO A COMPLETE STOP. I THEN GRADUALLY ACCELERATED AND SHIFTED MANUALLY, BUT WAS ONLY ABLE TO ACHEIVE 1ST GEAR. I HAD TO HAVE THE VEHICLE TOWED 150 MILES TO MY HOUSE WHERE IT STILL SITS THREE MONTHS LATER WITH ONLY REVERSE AND 1ST GEAR OPERABLE AT THIS TIME.
