AUTOMATIC TRANSAXLE SYSTEM


  1. OUTLINE


    1. A U881E 8-speed Super Electronically Controlled Transaxle (Super ECT) is used on 2WD models with 2GR-FKS engine.

    2. A gate type shift lever with boot is used.

    3. A multi-mode automatic transmission is used.

    4. A drive mode select is provided to select the drive mode (ECO, NORMAL, SPORT*1 or SPORT S/S+*2). In SPORT*1 or SPORT S/S+*2 mode, a higher level of responsiveness and a linear acceleration feel have been achieved.

      *1: Models without adaptive variable suspension system

      *2: Models with adaptive variable suspension system

    5. A Gear Shift Indicator system is used on models for Europe excluding package model options for Russia.

    6. A differential pre-torque mechanism is used. Straightline stability and acceleration performance during periods of low load and low differential rotation when the vehicle is being driven normally are ensured.

    7. An ATF cooler (oil cooler assembly) is provided in the ATF cooling system.
