Line pressure (1) regulated by the regulator valve f l o w s 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 follows:
• The shift solenoid valve A is OFF, and closes the port of shift solenoid valve A pressure (SA); shift valve A stays on
the left side.
• The shift solenoid valve B is t u r n e d O N , 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 and shift
valve D move to the right side.
• The shift solenoid valve D is OFF, and closes the port of shift solenoid valve D pressure (SD).
Line pressure (1) also f l o w s to the modulator valve and becomes modulator pressure (6). M o d u l a t o r pressure (6) f l o w s
to the A/T clutch pressure control solenoid valves. The manual valve covers the port leading pressure to the clutches,
and hydraulic pressure is not applied to the clutches.
