Hydraulic Flow (cont'd)
1 Position
The PCM turns the shift solenoid valves OFF and ON. The conditions of the shift solenoid valves and the positions of
the shift valves are as follows:
• Shift solenoid valve A: ON, and shift valve A moves to the left side
• Shift solenoid valve B: ON, and shift valve B moves to the left side
• Shift solenoid valve C: ON, and shift valve C moves to the left side
• Shift solenoid valve D: OFF, and shift valve D remains on the in left side
• Shift solenoid valve E: OFF, and shift valve E remains on the in left side
Line pressure (1) becomes 1st clutch pressure (10) at shift valve B.
Fluid flows to 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.
NOTE: When used, ''left'' or ''right'' indicates direction on the hydraulic circuit.
