CVT SYSTEM


  1. OUTLINE


    1. A K312 Continuously Variable Transaxle (CVT) is used.

    2. A 7-speed sport sequential shiftmatic mode with shift paddle switch (transmission shift switch assembly) is used.

    3. A SPORT mode switch (pattern select switch assembly) is used.

    4. A gate type shift lever is used.

    5. A shift lock system is used to prevent the shift lever from being wrongly operated.

    6. A coaxial 2 discharge port oil pump system is used.
