  3. MAIN FEATURES


    1. Automatic Transmission Breather System


      1. An automatic transmission breather system is adopted, helping to avoid loss of ATF from the breather during sporty driving involving quick turns and rapid braking.

      2. This system uses the labyrinthine structure of the breather tube to separate bubbles made up of air and ATF into air and liquid, preventing loss of ATF via the breather tank.
