摘要: A shift control apparatus for an automatic transmission including a gear train having a plurality of one-way clutches having their engagement states switched in accordance with torque applying directions and a plurality of frictional engagement units adapted to be engaged by oil pressures. The apparatus comprises a controller for engaging a first one of the frictional engagement units so as to maintain a predetermined gear stage after any of the one-way clutches has been engaged or released, if a predetermined condition is satisfied after the one-way clutch has been engaged or released to start a shift to the predetermined gear stage.
