What's the 2004 Toyota Highlander transmission fluid type?

The 2004 Toyota Highlander uses Dexron ViAutomatic transmission fluid in it. This is a good synthetic fluid and will help protect the gears in Your transmission from any damage. I recommend that You check Your transmission fluid every time that You get Your oil changed. You will want to make sure that it is full and free from signs of debris. Debris in transmission fluid will make it look reflective or sparkly because they are metal filings that get into the fluid from damaged gears. It is important to change Your transmission fluid every 30,000 miles to help keep the gears in Your vehicle protected and free from damage. The transmission is one of the most expensive components in Your car and something You do not want to break.
