1996 Chevrolet K1500

TRANSMISSION FAILURE DUE TO FAULTY SUN SHELL I'M WRITING TO INFORM YOU OF A SERIOUS TRANSMISSION PROBLEM WHICH NEEDS TO BE ADDRESSED. FOR THE SECOND TIME IN 3 AND A HALF YEARS, I'VE HAD A GM 4L60-E TRANSMISSION REBUILT BECAUSE OF THE SUN SHELL SHEARING OFF AND DAMAGING INTERNAL PARTS INSIDE THE HOUSING ON TWO SEPARATE VEHICLES. AFTER DOING A LITTLE RESEARCH AND FINDING 3 NEIGHBORS WHO HAD THE SAME PROBLEM, IT WAS CLEAR THERE WAS A PATTERN. ADDITIONALLY, INFORMATION ON THE INTERNET CONFIRMED MY SUSPICION, AS GM IS OBVIOUSLY AWARE OF THE INHERENT PROBLEM, AND TRANSMISSION CENTERS ARE VERY AWARE OF THE PROBLEM, AND HENCE ROUTINELY STOCK KITS NECESSARY TO REPAIR THE DAMAGE FROM THE FAILED SHELL, NOT TO MENTION THE TCC VALVE ISSUE. I'VE OWNED A NUMBER OF GM VEHICLES AND OWN TWO NOW A 1996 K1500 PICKUP AND A 1999 TAHOE. AS MENTIONED ABOVE, BOTH HAD THE SAME DEFECT AND CONSEQUENTLY NEEDED TO BE REBUILT NOT AN INEXPENSIVE ITEM. WHILE I SUPPORT AMERICAN AUTO MANUFACTURERS, I AM SADLY DISAPPOINTED IN THE FAILURE OF NOT ONLY THE DEFECTIVE PART, BUT ALSO IN GMS COMMITMENT TO THEIR LOYAL CUSTOMERS. IN 2004, GM FINALLY ADDRESSED THE FAULTY SUN SHELL AND HAS BEGUN PUTTING IN A STRONGER MACHINED (NOT WELDED) PART IN THOSE TRANSMISSIONS. HOWEVER, FOR THE MAJORITY OF CHEVROLET TRUCK OWNERS PRE 2004, WE HAVE BEEN STUCK WITH THIS DEFECTIVE PART AND CONSEQUENTLY REPLACED/REBUILT THE TRANSMISSIONS DUE TO ITS FAILURE.

I WAS DRIVING DOWN THE HIGHWAY AT 65 MPH AND MY TRANSFER CASE ON MY FOUR WHEEL DRIVE THREW ITSELF INTO 4 LOW. WHICH CAUSED MY TRUCK TO SKID OUT OF CONTROL . I MANAGED TO GAIN CONTROL OF MY VEHICLE AND PULL OF ONTO THE SHOULDER WHERE I DISCONNECTED THE BOX THAT CONTROLS THE TRANSFER CASE. THIS GAVE ME TWO WHEEL DRIVE WHICH GOT ME HOME. BUT I AM AFRAID TO HOOK THE BOX BACK UP IN FEAR OF KILLING MYSELF OR OTHERS IF THIS SHOULD HAPPEN AT HIGH SPEED AGAIN.*AK

AT 70,000 MILES THE TRANSMISSION ON MY 1996 CHEVY Z71 WENT OUT, WHICH ALSO TOOK THE TRANSFER CASE OUT. THE TRUCK WAS ALWAYS MAINTAINED ON TIME AND BABIED. I HAVE OWNED IT SINCE IT WAS NEW. OF COURSE THE WARRANTY IS UP SO I AM STUCK WITH THE BILL. I HAVE BEEN RESEARCHING ONLINE AND I AM NOT THE ONLY ONE WITH THE SAME PROBLEM. THESE PROBLEMS SEEM TO BE VERY COMMON AMONG 96-98 OWNERS. CALLING GM DOES NOTHING. PLEASE FORCE THEM TO DO SOMETHING ABOUT THIS PROBLEM. *JB
