摘要：A control system for an automatic transmission includes a downshift controlsection configured to increase an engaging capacity of an engaging-side engagingelement to engage the engaging-side engaging element and decrease a first engaging
capacity of a disengaging-side engaging element to disengage the disengaging-sideengaging element when a parameter representing a progressing condition of thedownshift reaches a value, thereby carrying out the downshift in a power-on condition.Additionally, the downshift control section is configured to decrease the engagingcapacity of the disengaging-side engaging element to a second engaging capacitysmaller than the first engaging capacity to continue the downshift which is currentlyprogressing and to cause the engine control section to continue controlling the enginespeed when a power-off condition is detected upon an accelerator pedal being returnedto a position representing an operating amount during the downshift.
