Hydraulic operation – 1

Line pressure (1) becomes line pressure (4) at the manual valve and passes to the 1st clutch and 1st accumulator. Then line pressure (4) flows through the 1st-hold clutch and 1st-hold accumulator. The power is transmitted only during deceleration through the 1st-hold clutch.

Line pressure (4) is applied to 1-2 shift valve and 2-3 shift valve.

3rd clutch pressure (31) is applied to 3-4 shift valve.

4th clutch pressure (41) is applied to the manual valve.

1st hold clutch pressure (16) is applied to the 1st hold clutch.

The modulator pressure (6) is supplied to the 1-2 and 2-3 shift valves.

The line pressure (1) also flows to throttle valve B.
