Abstract: In an automatic transmission including a torque converter, the transmission mechanism is capable of performing lock-up function. The input side portion of a first clutch is coupled with the turbine of the torque converter, wherein the first clutch is in connection while the automatic transmission mechanism is in forward one, forward two and forward three speed, respectively. The input side portion of a third clutch is coupled with the impeller of the torque converter, wherein the third clutch is in cut-off during forward one and two speed and in connection during high speed stages (three speed and four speed, for instance).Thus, in low speed states (one speed and two speed), the torque is transferred through the oil flow of the torque converter, and in high speed states (three speed and four speed), the torque which is machanically coupled with the engine output shaft is transfered to the automatic transmission mechanism.
