I am a new club member. I own a 2000 ES300 (purchased new) and was told by Lexus of Silver Spring, Maryland that my transmission is gone. It would cost $6000 for them to put in a new one but I understand it is really a rebuilt one. I do not intend to pay this amount for Lexus to repair and have sought estimates from other auto shops. The car has approximately 131,500 miles on it. Is it realistic that a 6-year old Lexus would need a new transmission? I know the miles are high but I have seen, even in this forum, that others have had cars that have more mileage than this and have not had to replace their transmission. I really never had the transmission flushed but recently, when I started having problems. Was that a mistake not to get regular flushes -- whatever that means?
