摘要:
A vehicle automatic transmission includes: a plurality of rotating elements disposed rotatably relative to a transmission case; clutches each disposed between two rotating elements of the plurality of the rotating elements to be engaged to inhibit relative rotation between the two rotating elements and released to allow relative rotation between the two rotating elements, the clutches not including those engaged to directly couple the rotating elements to the transmission case and selectively establishing multiple shift stages achieved in the automatic transmission depending on a combination of engagement and release of the clutches, the vehicle automatic transmission, including three planetary gear devices and the six clutches, the plurality of the rotating elements being configured to include sun gears, carriers, and ring gears of the three respective planetary gear devices, and each of the multiple shift stages being established by engaging four clutches and releasing the remaining two clutches.
