摘要：
A gear shift controlling apparatus of an automatic transmission for a vehicle has a synchronization-time engagement pressure correcting device that, before synchronization of gear-shifting, makes an increase correction of an engagement pressure of the disengaged-side engaging element by a first prescribed amount, to cause an input shaft rotational speed immediately before synchronizing of the automatic transmission to approach a rotational speed calculated by multiplying an output shaft rotational speed by a gear ratio of a gear after gear-shifting the automatic transmission.
