PURPOSE: A shift control learning method of an auto transmission is provided to improve speed change feeling by combining solenoid learning with shift learning at the same time. CONSTITUTION: An auto transmission confirms whether solenoid control learning is completed or not(S10). The auto transmission confirms a speed change type of speed change(S20). The auto transmission revises initial solenoid pressure deviation(S30). The auto transmission revises speed change deviation involved in speed change control(S40). The auto transmission detects all kinds of the signals created in a current speed change state(S50). Whether all kinds of detected signal value data are included in a solenoid learning designated area or is included in a speed change learning designated area is determined(S60).
