AUTOMATIC TRANSAXLE SYSTEM


  1. OUTLINE


    1. A U760E automatic transaxle is used. This automatic transaxle is a compact, lightweight and high-capacity 6-speed super Electronically Controlled Transaxle (ECT).

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

    3. A multi-mode automatic transmission is used.

    4. 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.

    5. An ATF warmer is provided in the ATF cooling system on models without air cooled oil cooler.

    6. An ATF warmer and air cooled oil cooler are provided in the ATF cooling system on models with air cooled oil cooler.
