AUTOMATIC TRANSAXLE SYSTEM


  1. OUTLINE


    1. The U660F 6-speed Super Electronically Controlled Transaxle (Super ECT) is used on models with 2AD-FTV or 2AD-FHV engines.

    2. In addition to the water-cooled type ATF cooler, an air-cooled type ATF cooler is used in the ATF cooling system.

    3. A gate type shift lever is used.

    4. A multi-mode automatic transmission is used.

    5. A shift paddle is used on the XLE (Middle) or LIMITED (High) grade except for basic packages or RHD models with 2AD-FTV engines.

    6. A shift pattern select system is used to select the driving mode (Normal and Sport). In Sport mode, a higher level of responsiveness and a linear acceleration feel have been achieved.

    7. A Gear Shift Indicator system is used on RHD models with 2AD-FTV engines except for destination packages for Australia or on models with 2AD-FHV engines.
