System Description (cont'd)
Hydraulic Flow (cont'd)
D Position: Driving in 4th gear
The PCM turns shift solenoid valve A ON, and B, C, 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 cover the A/T clutch pressure control
solenoid valve A and C pressure ports leading to the 2nd and 3rd clutches.
A/T clutch pressure control solenoid valve B pressure (56) changes to (5G) at shift valve C, and becomes 4th clutch
pressure (40) at shift valve B. 4th clutch pressure (40) is held high by A/T clutch pressure control solenoid valve B, and
the 4th clutch is engaged securely.
NOTE: When used, ''left'' or ''right'' indicates direction on the hydraulic circuit.
