Claims

[Claims for Utility Model Registration] An automatic transmission in which a power transmission path is determined by selectively operating various friction elements using line pressure, and the transmission is performed by changing this power transmission path by switching the operation of the friction elements. A line pressure control device for an automatic transmission, comprising: a shift detecting means for detecting the shift; and a line pressure increasing means for increasing the line pressure during shifting.
