1995 Hyundai Sonata Power Train

I'M THE OWNER OF A 1995 HYUNDAI SONATA, 2.0L DOHC, AUTOMATIC. DRIVING ON A ICY ROAD IN MICHIGAN THE TRANNY DOWNSHIFTED BY ITSELF FROM 4TH(OD) TO 1ST GEAR AND LOCKED IN 1ST GEAR THROWING ME IN A SNOW BANK! IF IT WASN'T FOR THE SNOW BANK TO STOP THE CAR, I WOULD'VE ENDED IN FRONT OF A INCOMING SEMI! THE TRANSMISSION HAS HAD HARSH SHIFTS/DOWNSHIFTS SINCE I PURCHASED THE CAR, BUT I NEVER HAD ANTICIPATED LOCKING UP WHILE DRIVING. AFTER DOING SOME RESEARCH I FOUND A HYNUDAI TECHNICAL SERVICE BULLETIN STATING THAT 1995 MODEL TRANSMISSIONS CONTROL UNITS MAY NEED TO BE REFLASHED WITH NEWER VERSION SOFTWARE OR REPLACED WITH NEWER UNITS. APPARENTLY HYUNDAI DIDN'T MAKE A PRIORITY IN NOTIFYING THE OWNERS ABOUT THE TRANSMISSION COMPUTER CAUSING ERRATIC SHIFTS/DOWNSHIFTS! AFTER TALKING TO A HYUNDAI DEALERSHIP ABOUT THE ISSUE I GOT THE FOLLOWING ANSWER: "THE 1995 MODEL SONATA IS KNOWN FOR RANDOM TRANSMISSION PROBLEMS, AND LIMPING MODE ISSUES? .." I WAS SPEECHLESS KNOWING OTHER PEOPLE OWN AND DRIVE THIS MODEL AND THAT SAME THING MAY HAPPEN TO THEM. PLEASE, SOMEBODY NEEDS TO DO SOMETHING ABOUT THIS ISSUE. *TR

MY TRANSMISSION WILL NOT PULL FORWARD ONLY IN REVERSE AND I HAVE BEEN DOING A LOT OF RESEARCH ON THIS TRANSMISSION AND THERES A NUMEROUS AMOUNT OF PEOPLE WHO OWN THE EXACT SAME CAR AS I DO THAT HAD THE EXACT SAME PROBLEMS. YOU CANT FIND LOCAL MECHANICS TO WORK ON THEM BECAUSE THE TRANSMISSION IS SO COMPLEX. AND BEINGS THAT SO MANY PEOPLE ACROSS AMERICA ARE HAVEING THE SAME PROBLEMS WITH THE SAME CAR THE COMPANY SHOULD HONOR THEIR COMPANY AND ADMIT THE TRANSMISSIONS ARE FAULTY AND RECALL THEM. *AK
