Hydraulic Flow (cont'd)

The PCM controls the shift solenoid valves and the A/T clutch pressure control solenoid valves. The conditions of the

shift control solenoid valves and the positions of the shift valve are as follows:

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

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

• Shift solenoid valve C is turned ON, and the shift valve C stays on the right side.

Line pressure (4) becomes line pressure (5B) at shift valve C. Line pressure (5C) flows to shift valve B via shift valve A,

and becomes 1st clutch pressure (10). 1st clutch pressure (10) is applied to the 1st clutch, then 1st clutch is engaged.

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