Pressure Control Solenoid Valve
This valve has its duty controlled by the transaxle
mand to corresponding hydraulic pressure.
N-R Control Valve
This valve prevents shock from occurring when the
select lever is shifted from "N" to "R" (or from "P"
to "R") by controlling the oil pressure applied to the
low-reverse brake.
Line pressure
pressure control valve moves to the left under the
line pressure which acts on the difference in area
between the pressure control valve # 1 and #2
lands and the reducing pressure which acts on the
difference in area between the #2 and #3 lands,
thus closing the No. 5 port by its #2 land. This
reduces the No. 10 port pressure and the pressure
control valve is moved to the right by the spring
force. Through the No.5 port thus opened, the line
pressure is directed to the kickdown servo. The
pressure applied to the kickdown servo is adjusted
by the above-mentioned sequence.
