ACCUMULATORS NO. 1 AND NO. 2
These valves dampen the increase in hydraulic
pressure applied to the tightening side of the 2
nd
brake band servo and hydraulic pressure applied
to the forward clutch.
1–2 SHIFT VALVE
This valve shifts up or down between 1
st
gear and
2
nd
gear and is operated by the shift solenoid No. 2.
Shifts to 1st gear when line pressure is applied
only to 1 on the shift valve.
In 1st gear, the 6–7 passage is open, 2 and 3 are
closed. 5 is drained. In 2
nd
and 3
rd
gears and in
reverse, the 2–5 and 3–6 passages are open, and
7 is closed.
2–3 SHIFT VALVE
This valve shifts up or down between 2
nd
gear and
3
rd
gear and is operated by the shift solenoid No. 1.
Shifts to 3rd gear when line pressure is applied to
1 on the shift valve.
In 1
st
and 2
nd
gears and reverse, 3–6 passage is
open, and 2 is closed. 4 is drained.
In 3
rd
gear, the 2–4 passage is open, and 3 is
closed. 5 is drained.
SHIFT SOLENOIDS NO. 1 (DIRECT CLUTCH
SOLENOID) AND NO. 2 (2ND BRAKE SOLE-
NOID)
These solenoid valves control the pilot pressure
that operates the shift valves.
When ON, the drain port on the valve operation
side is open, and when OFF it is closed.
SOLENOID VALVE NO. 3 (2ND BRAKE
SERVO SET)
This valve restricts abrupt operation when the 2nd
brake band servo is operated, and is not directly
related to shifting.
