Abstract
A manual valve disconnects a line pressure oil passage and an R position pressure oil passage when a selector is in a D position or an N position and causes the R position pressure oil passage and the line pressure oil passage to communicate when the selector is in an R position. A switching valve is switched to disconnect a low & reverse brake pressure oil passage and the R position pressure oil passage when the selector is in the D position or the N position and a vehicle is driving at a vehicle speed equal to or lower than a predetermined vehicle speed.
