1997 GMC SIERRA Power Trainautomatic Transmission Problems

THERE IS A HARD SHIFT BETWEEN 1 AND 2 GEARS AFTER DRIVING SEVERAL MILES.*AK

AFTER DRIVING FOR ABOUT 1 HOUR ON THE HIGHWAY, WE EXITED AND CAME TO A STOPLIGHT THAT IS WHEN THE TRANSMISSION STARTED SHIFTING HARD FROM FIRST TO SECOND GEAR. WHEN I GOT HOME I WENT ON-LINE AND THAT IS WHEN I REALIZED THAT I AM NOT THE ONLY 1997 GMC SIERRA OWNER THAT HAS THIS VERY SAME PROBLEM, THERE ARE LITERALLY HUNDREDS IF NOT THOUSANDS OF US OUT THERE WITH THE EXACT PROBLEMS WITH THIS VEHICLE. I WOULD LIKE TO KNOW IF THERE IS A RECALL BEING CONSIDERED AT THIS TIME?*AK

EARLY TRANSMISSION FAILURE (CODE 1870). *AK

AFTER A LONG RUN THE TRANSMISSION SHIFTS HARD FROM 1ST TO 2ND, CONDITION LEADS EVENTUALLY TO TRANSMISSION FAILURE.*AK

WHILE DRIVING ABOUT 20 MPH CONSUMER HEARD A NOISE AND VEHICLE SLOWED DOWN, TRANSMISSION HAD GONE OUT. *AK CONSUMER STATES WHILE DRIVING THERE WAS A NOSIE AND VEHICLE WOULD NOT SHIFT INTO 2ND, 4TH, OR REVERSE AND HAD NO COMPRESSION BRAKING ON A HILL .*JB

AUTOMATIC TRANSMISSION FAILED. NLM

DATE IS APPROXIMATE, HAVE SINCE HAD PROBLEM WITH SAME MODEL TRANSMISSION ON ANOTHER 1997 TRUCK. *AK

NO SUMMARY

TRANSMISSION HARD SHIFTS FROM 1-2ND AFTER DRIVING FOR SEVERAL MILES. I CAN TURN OFF THE IGNITION AND THIS WILL SOLVE THE PROBLEM FOR ABOUT 10 MILES. THEN IT WILL START SHIFTING HARD AGAIN. ENGINE LIGHT IS ON. DEALER COULDN'T DIAGNOSE THE PROBLEM. *AK

BUMPS INTO GEAR, ENGINE CHECK LIGHT, TRANSMISSION OVERFLOW DRIPS, POWER STEERING PUMP NEEDS REPLACING

NO SUMMARY LISTED FOR ABOVE VEHICLE. *AK

VEHICLE STALLED WHILE DRIVING. HAD COASTED TO SIDE OF ROAD. RESTARTED & VEHICLE SHUT OFF. THE DIFFERENTIAL SEAL WAS LEAKING OIL. THE VEHICLE WAS MAKING NOISES IN THE UNIVERSAL JOINT. TAKING VEHICLE TO MECHANIC. ALSO, LEAF SPRING ON PASSENGER'S SID EFAILED/REPLACED/SMELLED OIL DUE TO PCV VALVE FAILURE, AN DTRANSMISSION WOULD NOT SHIFT INTO DRIVE OR REVERSE. *AK

I PURCHASED THIS TRUCK IN JANUARY 1998. 2 WEEKS LATER IT WAS IN THE SHOP. THIS PATTERN CONTINUED EACH TIME. THE COMPLAINT WAS CONCERNING TRANSMISSION. BUT EACH TIME THEY WOULD REPLACE SOMETHING ELSE INSTEAD. THE TRUCK WAS IN THE SHOP FOR OVER 50 DAYS IN A YEARS TIME. ON OCTOBER 4, 1999 I WAS ON MY WAY TO WORK WHEN THE TRUCK GOING DOWN THE HIGHWAY, JAMMED IN 1ST GEAR. THE TRUCK WAS TOWED. IT TOOK THE DEALER 10 DAYS TO MAKE A DECISION ON REPAIRING THE TRUCK. THEY WERE WELL AWARE OF THIS PROBLEM, AND IT IS STILL A MAJOR HASSLE TO GET IT REPAIRED. CONTACTED GM AND HAD TO HAVE THEM INTERVENE. HAD THEY OF FIXED THE TRUCK THE PRIOR 5 TIMES IT WAS IN FOR REPAIR THIS WOULDN'T HAVE HAPPENED. THEY CONTINUALLY DENIED PROBLEMS EXISTED WITH THE TRANSMISSION. THIS IS A VORTEX TRUCK I DON'T KNOW IF...

TRANS STARTED SHIFTING VERY HARD. ONCE IN HIGH GEAR OPERATED WELL. DEALER WOULD NOT LOOK AT IT UNDER WARRANTY EVEN THOUGH 1YR 10 MOS. OLD DUE TO OVER 36000 MILES BY LESS THAN 2000.

AUTOMATIC TRANSMISSION/ OVERDRIVE MALFUNCTIONED, CAUSING AN ABRUPT FORWARD JUMP FROM 1ST TO 2ND GEAR WHICH MAY CAUSE A CRASH. PLEASE PROVIDE FURTHER INFORMATION. *AK

TRANSMISSION DOES NOT SHIFT CORRECTLY, CAUSING LOUD NOISE AND POSSIBLY RESULTING IN TOTAL FAILURE. DEALER CANNOT FIX DEFECT. *AK

WHILE DRIVING THE VEHICLE EXPERIENCED SUDDEN ACCELERATION AT A HIGH SPEED WITHOUT PRIOR WARNING WHICH ALMOST RESULTED IN AN ACCIDENT. WAS ABLE TO STOP THE VEHICLE WITH THE BRAKES. ALSO, DEALER REPLACED THE TRANSMISSION. *AK

TRANSMISSION FAILED.
