ABSTRACT:
An automatic transmission having a turbine, a pump, a first stator and a second stator and a speed changer having a planetary gear train composed of first and second planetary gears sharing one planetary carrier in common and a clutch or brake for controlling the planetary gear train. The turbine of the torque converter is coupled to a turbine shaft which transmits power from the turbine to the speed changer. A first stator is provided at a turbine side between the turbine and the pump, the first stator being coupled to a first stator shaft for transmitting power from the first stator to the speed changer a one-way clutch. A second stator is provided at a pump side between the turbine and the pump. The second stator is connected to a housing though a second stator shaft having a one-way clutch for transmitting power in a direction reverse to the rotation direction of the pump. A clutch or brake for controlling rotation speed of the first stator shaft is provided in the course of the first stator shaft. A first sun gear meshing with the first planetary gear of the speed changer is fixed to an end portion of the turbine shaft. A second sun gear meshing with the second planetary gear of the speed changer is fixed to an end portion of the first stator shaft. A brake is provided at a clutch cover side of the clutch.
