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 t u r n e d O N , and closes the port of shift solenoid valve C pressure ( S O ; shift valve C and
shift valve D stay on the left side.
• The shift solenoid valve D is OFF, and closes the port of shift solenoid valve D pressure (SD).
Line pressure (4) becomes 1st clutch pressure (10) at the shift valve D, and f l o w s to the 1st clutch. The 1st clutch is
engaged. The PCM controls the A/T clutch pressure control solenoid valve C, and A/T clutch pressure control solenoid
valve C pressure (58) is applied to the CPC valve C via the lock-up shift valve. The CPC valve C regulates line pressure
(4), and line pressure (4) becomes CPC C pressure (4C). CPC C pressure (4C) f l o w s to the shift valve B via the shift
valves D, E, and C, and becomes 1st-hold clutch pressure (15) at the shift valve B. 1st-hold clutch pressure (15) is
applied to the 1st-hold clutch, and the 1st-hold clutch is engaged.
