Abstract: A shift control apparatus of an automatic transmission of a motor vehicle to which torque is transmitted from an engine via a fluid coupling device is provided. In the automatic transmission including a plurality of hydraulically operated friction elements, a clutch-to-clutch downshift is carried out during coasting of the vehicle by releasing one of the friction elements and engaging another friction element. A controller of the shift control apparatus detects a difference between input and output rotation speeds of the fluid coupling device, and increases an engine speed by a controlled amount based on the difference between the input and output rotation speeds when the clutch-to-clutch downshift is carried out during coasting of the vehicle, so that the vehicle is brought into a minimal driving state in which the engine speed is slightly higher than the output rotation speed of the fluid coupling device.

Abstract: To prevent the neutral state from being formed in a change gear apparatus and allow the obtaining of an intended gear change appropriately during a servo malfunction. Hydraulic servos engage and disengage a plurality of friction engagement elements; a hydraulic pressure supply system supplies the hydraulic servo of a predetermined friction engagement element with hydraulic pressure; and an auxiliary hydraulic pressure supply systems supplies a predetermined hydraulic servo with another hydraulic pressure, in the case where the hydraulic pressure supply system is placed in a first unsupplied state where the hydraulic pressure supply system cannot supply the hydraulic servo of the predetermined friction engagement element with hydraulic pressure. The auxiliary hydraulic pressure supply system does not supply the predetermined hydraulic servo with the other hydraulic pressure, in the case that the hydraulic pressure supply system is placed in a second unsupplied state where the hydraulic pressure supply system does not supply the hydraulic servo of the predetermined friction engagement element with hydraulic pressure.
