ABSTRACT:
A method and system for controlling a 3→2 shift before stopping of an automatic transmission reduces shift shock as a consequence of an operation of a control duty being delayed according to an angular velocity of an engine at a shift start point in the 3→2 shifting process before stopping. The method includes: detecting driving information; determining whether a 3→2 shift condition before stopping is satisfied; determining, when the 3→2 shift condition before stopping is satisfied, whether a shift control condition is satisfied; and controlling the 3→2 shift before stopping when the shift control condition is satisfied.
