Forgetting to replace your car’s transmission fluid and filter regularly is easy to do, but it can really harm your Isuzu, I-Mark. 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 Isuzu, I-Mark 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 Isuzu, I-Mark 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.
