2 Position
Line pressure (1) regulated by the regulator valve flows to shift solenoid valves. The PCM controls the shift solenoid
valves ON and OFF. The conditions of the shift solenoid valves and positions of the shift valve are as f o l l o w s :
• The shift solenoid valve A is turned O N , and opens the port of shift solenoid valve A pressure (SA); shift valve A
moves to the right side.
• The shift solenoid valve B is turned ON, and closes the port of shift solenoid valve B pressure (SB); shift valve B and
shift valve E stay on the left side.
• The shift solenoid valve C is OFF, and opens the port of shift solenoid valve C pressure (SC); shift valve C moves to
the right side and shift valve D stays on the left side.
• The shift solenoid valve D is OFF or O N , and closes or opens the port of shift solenoid valve D pressure (SD).
Line pressure (4) becomes 2nd clutch pressure (20) at the shift valve B via the shift valves C and A, and f l o w s to the
2nd clutch. The 2nd clutch is engaged. The 1st clutch is also engaged, but no power is transmitted because of the one-
w a y clutch.
