Chevrolet Silverado transmission problems

GOOD MORNING, I OWN A 1999 SILVERADO, LONG BED, WITH AN AUTOMATIC TRANSMISSION AND I AM HAVING A FEW PROBLEMS, ANY HELP YOU CAN PROVIDE WOULD BE GREATLY APPRECIATED... FIRST THE ABS MOTOR CONTINUES TO RUN AFTER THE ENGINE HAS BEEN SHUT OFF, I HAD TO DISCONNECT THE ABS FUSE SO THE BATTERY WILL NOT GET DRAINED. SECOND THE AUTOMATIC TRANSMISSION IS SHIFTING HARD FROM 1ST TO 2ND AND FROM 2ND TO 3RD, I AM FORCED TO SHUT THE ENGINE OFF FOR A COUPLE OF MINUTES AND WHEN I RESTART THE ENGINE THE PROBLEM DISAPPEAR, I HAVE READ YOUR SAFETY BULLETINS AND GM IS AWARE OF THESE PROBLEMS. MY TRUCK LOOKS AND ACTS PRACTICALLY LIKE NEW EXCEPT FOR THE INTERMITTENT TRANSMISSION PROBLEMS AND THE ABS. I HAD BABIED MY TRUCK SINCE I BOUGHT IT, AND I HAVE OWNED GM PRODUCTS ALL MY LIFE AND I DON'T THINK IS FAIR FOR ME TO SPEND THOUSANDS OF DOLLARS FOR GM'S MANUFACTURING PROBLEMS... PLEASE ADVICE... THANKS...!!!*JB

TRANSMISSION SLIPS DURING THE 1-2 UP SHIFT AT MODERATE THROTTLE INPUT CAUSING A DISTINCTIVE CLUNK AND COULD BE A POSSIBLE SAFETY CONCERN ON TWO WHEEL DRIVE VEHICLES ON SLIPPERY ROADS, WHERE AS VEHICLE LOSS OF CONTROL COULD OCCUR WHEN TRANSMISSION ENGAGES. VEHICLE RETURNED TO DEALER TWICE WITH CONCERN, ONE ATTEMPT TO FIX WITH REPLACEMENT OF TRANSMISSION OUTPUT SHAFT. THIS DID NOT HELP. *JB

AT 33,000 MILES, OCT 2002 -APPROXIMATELY 55MPH, ACTED LIKE IT WAS NOT IN GEAR THEN THE TRANSMISSION FLUID HOT LIGHT CAME ON. IMMEDIATELY PULLED OFF TO SIDE OF ROAD - CHECKED TRANSMISSION FLUID, IT CHECKED OK AND THE LIGHT WENT OFF. PULLED BACK ONTO HIGHWAY - IT WAS FINE. IMMEDIATELY TOOK TO LOCAL DEALERSHIP; THEY HOOKED IT UP TO THE COMPUTER AND DIDN'T FIND ANYTHING WRONG. IN JAN 2003, UPON ACCELERATION, AROUND 25-30MPH, IT ACTED AS THOUGH IT WOULDN'T GO INTO 3RD & 4TH GEAR. SAME AS OCT 2002, BUT NOTHING REGISTERED ON THE TRUCK'S MESSAGE CENTER THIS TIME. AND THIS TIME, THE PROBLEM DIDN'T GO AWAY. I TOOK TO ANOTHER LOCAL DEALER - MECHANIC DROVE VEHICLE AND NOTED THE PROBLEMS. STILL, NOTHING REGISTERED ON THE TRUCK'S MESSAGE CENTER. MECHANIC EVEN HOOKED UP THE TRUCK TO HIS COMPUTER AND DROVE IT WHILE IT WAS STILL FAILING. TO HIS SUPRISE, NOTHING REGISTERED ON HIS COMPUTER EITHER. THEY OVERHAULED THE TRANSMISSION - REPLACED 3RD & 4TH GEAR. THEY ADJUSTED THE BILL - AS IF I PURCHASED EXTENDED WARRENTY. CONTACTED GM - THEY REPORT THERE HAVE NOT BEEN ANY PROBLEMS LIKE THIS WITH THESE TRUCKS. "SOMETIMES THIS HAPPENS WHEN PEOPLE MAKE THINGS -IT'S UNFORTUNATE THAT IT HAPPENED TO YOU". AFTER THAT CALL - I FOUND THIS SITE AND FOUND A TECHNICAL BULLETIN REFERRING TO THIS SAME PROBLEM. VERY DISAPPOINTED WITH ONLY HAVING 36,000 MILES SINCE MARCH 1999.
