Forgetting to replace your car’s transmission fluid and filter regularly is easy to do, but it can really harm your Lexus, ES300. The transmission filter keeps the transmission fluid clean, and thus helps the entire transmission run smoothly. A clogged or dirty transmission filter can cause a transmission to wear out too quickly or perform erratically. Keeping the transmission fluid in a Lexus, ES300 clean is much easier if you remember to replace the transmission filter every 30,000 miles or every two years. The signs of a dirty filter or dirty transmission fluid are not always obvious. It might be time for a fluid and filter change if a Lexus, ES300 has varnish on its transmission dipstick, a sharp smell like burning rubber, rough shifting, buzzing or clicking sounds or transmission fluid that has changed to brown or yellow from its original red.
