LAST WEDNESDAY WHILE OUT ON

LAST WEDNESDAY WHILE OUT ON THE BACK ROADS, I DECIDED IT WOULD BE A GOOD TIME TO RUN THRU MY 4 WHEEL DRIVE (ELECTRONIC 2H, 4H, 4L, & ALL WHEEL), ALL OF THE SHIFTS WENT FINE, AND I THEN DROVE HOME. IN THE MORNING HOWEVER THE JIMMY WOULD NOT GO INTO REVERSE AND DID NOT HAVE DRIVE 3 OR DRIVE 2, ONLY LOW 1 TO DRIVE. I THEN HAD IT LOCK UP IN FOUR LOW AFTER I WAS CYCLING THRU THE 4 WHEEL DRIVE AGAIN TRYING TO REGAIN REVERSE, AFTER FINALLY GETTING IT OUT OF 4 LOW AND BACK INTO 2H (STILL NO REVERSE) I THEN PROCEDED TO PUT THE TRANFER CASE INTO NUETRAL BY HOLDING THE THE 2H BUTTON AND THE 4L BUTTON UNTIL THE TRANSFER CASE SHIFTED TO NEUTRAL. I THEN PUT IN REVERSE AND THEN TO DRIVE AND LOW AND BEHOLD DRIVE STILL ENGAGED WITH THE TRANSFER STILL IN NEUTRAL, I HAVE CONTINUE TO DRIVE IT IN DRIVE 1 TO DRIVE AND HAVE BEEN TAKING IT VERY EASY HOPING THAT WHAT EVER HAS STUCK SERVO WISE WILL LOSEN IT SELF AND COME BACK ON LINE. NOW KEEP IN MIND I HAVE NOT BEATEN THIS VEHICLE, NOR DID I GET IT STUCK AND HAMMER IT BACK AND FORTH BETWEEN DRIVE AND REVERSE, I MEARLY WAS SHIFTING THRU THE 4 WHEEL DRIVE, ANYONE WITH INSITE INTO THIS, YOUR HELP WOULD BE GREATLY APPRECIATED
