AUTOMATIC TRANSAXLE SYSTEM


  1. OUTLINE


    1. A U661F 6-speed Super Electronically Controlled Transaxle (Super ECT) is used on AWD models with 8AR-FTS engine.

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

    3. A multi-mode automatic transmission with the shift paddle switch 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 AVS

      • *2: Models with AVS

    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 warmer is provided in the ATF cooling system on models for general countries, Australia or Europe excluding package model options for Chile.

    8. An ATF warmer and an ATF cooler with transmission oil thermostat are provided in the ATF cooling system on models for G.C.C. countries or China or package model options for Chile.

    9. An electric oil pump is positioned parallel to the hydraulic circuit of the mechanical oil pump to ensure the oil pressure in order to achieve shock reduction and responsiveness when starting the engine from an idling stop on models for China or Australia excluding package model options for Brunei, Indonesia or Malaysia or package model options for Taiwan with stop and start system. As a result, a smooth start off is made possible. For details, refer to 8AR-FTS IDLING STOP CONTROL.
