Abstract
A control apparatus for an automatic transmission including three frictional engagement elements is configured to set engagement pressures of first and second frictional engagement elements at the time when a predetermined shift speed is established such that a torque capacity of a third frictional engagement element becomes smaller than torque capacities of the first and second frictional engagement elements in the case where an engagement pressure is generated in the third frictional engagement element at the time when the predetermined shift speed is established.
