    Abstract: This invention provides a switch valve which can increase durability without causing driver discomfort at a time when a failure occurs. The switch valve has a spool is formed by a spool portion and a plunger which is arranged so as to freely abut against the spool portion. The switch valve also include a spool surrounding portion surrounding the spool and provided with a plurality of land portions. The spool selectively adopts a position at a normal, non-failure state and a position at a fail state. In the position at the normal state, at least one corner portion of the land in the plunger protrudes from an end portion of the corresponding land portion. Because a stepped wear portion is not formed on an inner peripheral surface of the land portion, foreign materials, such as wear powders or the like, do not enter a portion between an outer peripheral surface of the land and the inner peripheral surface of the land portion when the failure occurs.

    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.
