Hydraulic Flow (cont'd)
1st gear shifting from N position
Shift solenoid valves remain the same as in N when shifting to D from N. The manual valve is moved to the D position, and switches the port of line pressure (4) leading to A/T clutch pressure control solenoid valve C. Hydraulic pressure to the 1st clutch from A/T clutch pressure control solenoid valve A is created as shift solenoid valve A is OFF, B and C remains ON. A/T clutch pressure control solenoid valve A pressure (55) changes to 1st clutch pressure (10) at shift valve B, and flows to the 1st clutch. The 1st clutch is engaged gently when shifting to D from N.
NOTE: When used, ‘‘left'' or ‘‘right'' indicates direction on the hydraulic circuit.
Driving in 1st gear in D and S with automatic shift mode
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) → Shift valve D−Line pressure (1A) → Shift valve A−Line pressure (1B) → Manual valve−Line pressure (5A) → Shift valve C−Line pressure (5B) → Shift valve B−1st clutch pressure (10) → 1st clutch
1st clutch pressure (10) is applied to the 1st clutch, and the 1st clutch is engaged securely.
