1998 SUBURBAN W/ 4L60E TRANSMISSION, SHIFTING HARD 1-2 AND 2-3. RESEARCH SHOWS IT IS A KNOWN PROBLEM OF MANUFACTURER ADDRESSES UNDER GM TECH SERV BULLETIN 01-07-30-023B. FURTHER, INTERNET SEARCH INDICATES THAT PROBLEM IS MANUFACTURERS DESIGN ERROR, AND THAT ONLY PERMANENT FIX IS TO USE AN AFTERMARKET SUPPLIERS RE-DESIGNED REPLACEMENT PART.

THE TRANSMISSION ON MY 1998 GMC SURBURBAN FAILED. I WAS TOLD BY THE DEALER AND ANOTHER TRANSMISSION SPECIALIST THAT THIS PARTICULAR PROBLEM HAS BEEN COMMON TO THE 1997-98 GMC AND CHEVROLET SURBURBANS, TAHOES AND COMPARABLE VEHICLES. IT IS NOT FAIR TO CONSUMERS FOR AN AUTO MAKER TO KNOW ABOUT SEVERE PROBLEMS LIKE THIS WITH VEHICLES AND NOT ISSUE A RECALL OR CORRECT THE PROBLEM. OF THE 86 COMPLAINTS LISTED ON YOUR WEBSITE FOR THIS MODEL, 7 INVOLVED AND OTHERS INVOLVED THE DRIVETRAIN WHICH CAN BE AN ASSOCIATED PROBLEM.

1998 GMC SUBURBAN TRANSMISSION PROBLEMS. OUR VEHICLE WAS SPECIAL ORDERED FROM GMAC IN 1997. THE ISSUES IN OUR TRANSMISSION STARTED LATE LAST SUMMER, 2002. THERE IS A VERY NOTICEABLE "BUMP" WHEN STARTING FROM A STANDSTILL AND GOING FROM 1ST TO 2ND AND 2ND TO 3RD GEARS. AS STATED IN OTHER COMPLAINTS THIS IS OUR FAMILY VEHICLE TRANSPORTING OR 3 SMALL CHILDREN. *NLM

BEGAN SHIFTING HARD FROM 1-2 AND 3-4. DOES SO AFTER DRIVING. CAN STOP AND TURN OFF ENGINE AND IT WILL STOP FOR A WHILE. I HAVE READ MANY SIMILAR COMPLAINTS. 3 AND 4 TRANSMISSIONS HAVE BEEN REPLACED AND SAME THING OCCURS AFTER 10-20,000 MILES. LOCAL DEALER SAYS IT IS A COMMON PROBLEM, BUT GMC WILL NOT COVER.*AK

TRANSMISSION FAILED DUE TO A CHANGE IN THE MANUFACTURING PROCESS ADMITTED BY GMC. THEY ARE AWARE THAT ON 1997-1999 MODELS OF THE SUBURBAN ( AND POSSIBLY OTHER GMC MODELS?) THE 4L60E TRANSMISSION WILL SUFFER A FATIGUE FAILURE OF THE SUN GEAR REACTION SHELL, CAUSING THE LOSS OF REVERSE, 2ND AND 4TH GEARS.*AK

THE TRANSMISSION FAILED AND WAS REBUILT, THE CONSUMER WAS ASKING REIMBURSMENT BECAUSE THE PROBLEM WAS CREATED BY CHANGE IN MANUFACTURING PROCESS. *YH CONSUMER WAS INFORMED THAT OTHER VEHICLES LIKE THESE HAVE HAD PROBLEMS WITH LOSING REVERSE, 2ND AND 4TH GEARS, THIS BEING CAUSED BY A CHANGE IN THE MANUFACTURING PROCESS FOR THE SUN GEAR REACTION SHELL, DURING PRODUCTION THE RADIUS OF THE AREA ATTACHING THE SPLINES ON THE SHELL TO THE SHELL HOUSING WAS REDUCED, LEADING TO A FATIGUE FAILURE OF THE SHELL. *SLC
