Hydraulic Flow (cont'd)
[]]
Position
Line pressure
(1)
flows to
the manual
valve
and
the modulator valve. Line pressure
(1) changes
to
line
pressure
(4)
at the
manual
valve.
and changes to
modulator pressure
at
the modulator
valve.
But
modulator
pressure
(6)
does not
flow to
each shift valve because
shift
control solenoid valves
A
and
B
are
turned ON by the
PCM.
Line pressure
(4) passes
through
the CPB valve
and the
epe
valve.
and
changes
to
line pressure
(5),
then flows to
the 1-2
shift
valve
.
Line
pressure (5) from
the
'-2
shift valve changes to 2nd clutch
pressure
(20)
at
the
2-3
shift valve.
The
2nd clutch
pressure
(20) is
applied
to the
2nd clutch
,
and
the 2nd
clutch is
engaged. Line pressure
(4)
passes through the '-2
shift valve
and the
orifice,
and
changes
to 1st
clutch pressure. The
1st clutch
pressure (10) also
flows to
the
1st
clutch.
However,
no power is
transmitted
because
of
the
one-way
clutch.
NOTE:
• When used,
"left" or
"
right"
indicates
direction
on
the
hydraulic
circuit
.
• The hydraulic circuit
shows the '97
-
98
models
(7 positions); the '99
-
00
models
(6
positions)
is similar.
