2004 Hyundai Accent Power Train

I OWN A 2004 HYUNDAI ACCENT. FOR THE PAST 3 YEARS THE TRANSMISSION HAS HAD SIGNIFICANT ISSUES. THE AUTOMATIC TRANSMISSION WILL RANDOMLY SLAM INTO A LOWER GEAR OR WILL GET STUCK IN A GEAR. THIS CAUSES SAFETY ISSUES DURING WINTER DRIVING BECAUSE THE VEHICLE LURCHES FORWARD AT TIMES WHEN SHIFTING. WHILE ATTEMPTING TO ENTER INTO TRAFFIC, THE CAR WILL BE STUCK IN 3 GEAR WHICH ALMOST HAS CAUSED AN ACCIDENT SEVERAL TIMES BY PULLING OUT TOO SLOW. I HAVE HAD IT IN TWICE TO THE TRANSMISSION SHOP AND THEY COULD NOT DIAGNOSE THE PROBLEM WITHOUT AN ENGINE CODE. THEY FLUSHED, FILLED AND PUT A NEW FILTER IN THE TRANSMISSION BUT THIS DID NOT HELP. SOMETIMES THE CAR WILL WORK FINE FOR MONTHS OR A YEAR AT A TIME. I HAVE RESEARCHED THE PROBLEM ON THE INTERNET AND THERE SEEMS TO BE MANY OWNERS THAT HAVE VOICED SIMILAR CONCERNS. *TR

TRANSMISSION FAILED TO GO INTO OVERDRIVE WHILE TRYING TO PASS, DECELERATED FROM 65 TO 35, WENT IN NEUTRAL, THEN INTO A NORMAL GEAR. *NM

TRANSMISSION STARTED FAILING WITHIN THE FIRST 30 DAYS OF PURCHASE, EVER TIME IT WENT OVER 10 MPH IT LUGGED BACK AND THEN WENT FORWARD. BOUGHT THE CAR USED WITH 42K MILES AND THE SERVICE DEPARTMENT AT THE DEALERSHIP SAID THAT THEY WILL HAVE TO KEEL THE CAR TO REPLACE TRANSMISSION OR CHANGE A PART.

VEHICLE WILL NOT SHIFT GEARS. WHEN TAKEN TO GET SERVICED THE FIRST TIME CONSUMER WAS TOLD IT WAS DUE TO GAS FLOODING. THIS HAPPENED A SECOND TIME. WHEN TAKEN TO GET SERVICED AGAIN SHE WAS TOLD IT WAS DUE TO AIR ENTERING THE CLUTCH. CURRENTLY, IT HAPPENED A THIRD TIME.*AK

WHILE DRIVING TRANSMISSION DOWN SHIFTED ON ITS OWN. CONSUMER WAS ABLE TO MAINTAIN CONTROL OF THE VEHICLE ,AND DROVE THE VEHICLE TO THE DEALER FOR INSPECTION. MECHANIC DETERMINED THAT COMPUTER NEEDED TO BE RESET, AND RESET IT, BUT THE PROBLEM STILL OCCURRED. *AK
