SINCE JANUARY 25,1999, MY ML430 HAS BEEN IN THE SERVICE DEPT. A TOTAL OF 18 DAYS. ON TWO OF THOSE OCCASIONS, MY VEHICLE'S TRANSMISSION WOULD SHIFT INTO NEUTRAL WHILE DRIVING AT SPEEDS OF 35MPH. AFTER TWO ATTEMPTS, DEALER FINALLY FOUND DEFECT AND REPLACED PARTS OF TRANSMISSION. NOW IN FEBRUARY 2000, MY TRANSMISSION IS HAVING PROBLEMS AGAIN. THIS TIME A MODULE HAS TO BE REPLACED. I HOPE THESE DEFECTS WILL END SOON. I FEEL THAT I HAVE PURCHASED A LEMON. THANK YOU . RACHEL HARRIS (RAH0910@AOL.COM). *AK
