Description
Hydraulic Flow (cont'd)
3rd Speed
The tlow of fluid up to the 1-2 and 2 3 shift valves is the same as in 2nd speed. As the speed of the car reaches
the prescribed value, the shift control solenoid valve B is turned off {shilt control solenoid valve A remains on). The
2-3 shift valve is then moved to the left, uncovering the oil port leading to the 3rd clutch. Since the 3-4 shitt valve
is moved to the right to cover the oil port to the 4th clutch, the 3rd clutch is turned on.
Fluid tlows by way of:
- Line pressure l4l -
1-2 shift valve - 23 Shift Valve * 3rd ctutch pressure (31) -
3-4 shift valve
(not controlled) 3rd Clutch Pressure (3O) - 3rd Clutch
The hydraulic pressure also flows to the l st clutch. However, no power is transmitted because of the one-way clutch
as in the 2nd speed.
