System Description (cont'd)
Hydraulic Flow (cont'd)
D Position: Driving in 2nd gear
The PCM turns shift solenoid valves C OFF, D ON, and A and E remain OFF, and B remains ON. Shift solenoid valve C
pressure (SC) in the right side of the shift valve C is released. Shift valve C moves to the right side to switch the ports.
This movement covers the A/T clutch pressure control solenoid valve pressure ports to stop at shift valves C and A,
and uncover the line pressure port leading to the 2nd clutch.
Fluid flows to 2nd clutch by way of:
Line pressure (1)
pressure (5F)
2nd clutch pressure (20) is applied to the 2nd clutch, and the 2nd clutch is engaged securely.
NOTE: When used, ''left'' or ''right'' indicates direction on the hydraulic circuit.
