ABSTRACT:
A fluid pressure control device having a timing valve with a spool which is adopted in an automatic transmission so as to operate in such a manner that a fluid pressure from a friction portion at a low speed side to the timing valve is drained rapidly therefrom due to axial movement of the spool according to a signal indicating an engine output upon a power-off up-shifting is comprised of a first pressure source from which a pressure indicating the engine output is set to be applied to one end of the spool, a second pressure source from which a pressure is set to be applied to the other end of the spool so as to be balanced with the pressure from the first pressure source across the spool other than the power-off up-shifting, and a device for increasing the pressure applied to one end of the spool from the first pressure source on the basis of a condition relating to an accelerator upon power-off up-shifting.
