System Description (cont'd)
Hydraulic Flow (cont'd)
D Position: Driving in 1st gear
The PCM turns shift solenoid valve A ON, and B and C remain ON, and D and E remain OFF. Shift solenoid valve A
pressure (SA) is applied to the right side of shift valve A. Shift valve A is moved to the left side to uncover the line
pressure port leading to the 1st clutch, and to cover the A/T clutch pressure control solenoid valve pressure port.
Fluid flows to the 1st clutch by way of:
Line pressure (1)
pressure (5A)
1st clutch pressure (10) is applied to the 1st clutch, and the 1st clutch is engaged securely.
NOTE: When used, ''left'' or ''right'' indicates direction on the hydraulic circuit.
