Picked up a 1988 Buick Park Avenue with 103,000 miles and was thinking about changing the automatic transmission fluid. I am worried that the mileage might be too high to change it at this point (assuming it has never been done before). Anyone have any opinions about whether or not I should change the fluid? I’m a firm believer in maintenance but sometimes like to leave automatic transmissions alone if they have some mileage and haven’t had the fluid changed at regular intervals. Thanks.
