PROBLEM TO BE SOLVED: To provide a shift control device of an automatic transmission capable of suppressing variation in engagement time of a frictional engagement element caused by individual difference of an automatic transmission.SOLUTION: Engagement of a frictional engagement element is performed with two stages, and on the basis of the difference between a predetermined target time from shift start until a turbine rotation increase signal is output, and an actual time, backlash elimination control of the frictional engagement element performs learning correction to a hydraulic pressure supply time.SELECTED DRAWING: Figure 1 |
