To provide an automatic transmission which can prevent affection on durability.SOLUTION: There is provided an automatic transmission in which one of front and rear wheels can be driven by a rear motor and the other of the front and rear wheels can be driven by an internal combustion engine, and which changes rotational speed of the internal combustion engine. A control part performs control so that a cut-off part becomes a state capable of supplying an engagement pressure P, Pto a hydraulic servo in an EV travel state and in the case of being less than a set vehicle speed VA, and the cut-off part becomes a state of cutting off supply of the engagement pressure P, Pto the hydraulic servo in the case of being the set vehicle speed VA or more.SELECTED DRAWING: Figure 7

    【課題】耐久性に影響を及ぼすことを防止することが可能な自動変速機を提供する。【解決手段】自動変速機は、前後輪の一方がリヤモータにより駆動可能であり、前後輪の他方が内燃エンジンにより駆動可能であり、内燃エンジンの回転を変速する。制御部は、EV走行状態にあって、設定された設定車速VA未満である場合に、遮断部が、油圧サーボに係合圧PC1,PB2を供給可能な状態となるように、設定車速VA以上である場合に、遮断部が、油圧サーボに対する係合圧PC1,PB2の供給を遮断する状態となるように制御する。【選択図】図7
