This synthetic transmission fluid, characterized by its green color and unpleasant odor, is designed for use in the latest 9-speed automatic transmissions found in certain Honda Pilots, Acura MDX, and Acura TLX models. If your Honda or Acura is equipped with a 'push-button' shifter instead of a traditional gear shifter, this is probably the fluid that would be drained and refilled during service. Accurate Automotive advises changing this fluid in Honda and Acura vehicles annually or every 15,000 miles, whichever comes first.
