Driving in 1st gear
WARNING: This page is about a different variant/trim than selected.
The PCM turns shift solenoid valve A ON, 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.
NOTE:
When used, "left" or "right" indicates direction on the hydraulic circuit.
