ABSTRACT:
In an automatic transmission for a vehicle having an input rotational member, an output rotational member, a rotational speed change gear mechanism, clutches and brakes for changing a route of transmittance of torque between the input rotational member and the output rotational member through the rotational speed change gear mechanism in accordance with selective engagement and disengagement of the clutches and brakes so as to provide a plurality of forward speed stages and a reverse stage, a first one of the clutches is constructed to house a second one of the clutches at a radially inside thereof with a piston member of the first clutch serving as a member for transmitting torque through the second clutch, the second clutch being never engaged immediately after disengagement of the first clutch under any operating condition of the vehicle.
