Hydraulic Flow (cont'd)

The PCM controls the shift solenoid valves. The conditions of the shift solenoid valve and positions of the shift valve

are as follows:

• The shift solenoid valve A is turned OFF, and the shift valve A moves to the left side.

• The shift solenoid valve B is turned ON, and the shift valve B stays on the right side.

• The shift solenoid valve C is turned OFF, and the shift valve C stays on the left side.

Line pressure (1) passes through the manual valve and stops at shift valve D. Line pressure (1) also flows to the

modulator valve, and becomes modulator pressure (6). Modulator pressure (6) flows to the shift solenoid valves and

the A/T clutch pressure control solenoid valves. Under this condition, hydraulic pressure is not applied to the clutches.

NOTE: When used, ''left'' or ''right'' indicates direction on the hydraulic circuit.
