Solenoid

downshift

This
valve

is
a
transfer
valve
which

leads
the

and

transmits
the
same

the
FSV
and

SSV
when
a

signal
is
re

ceived
from

the
downshift
solenoid

Usually
the
solenoid

push
rod
and

valve
are
locked

upward
by
the

spring

in
the
lower
end
and
the
circuit
from

line

4
to
line

13
is

opened

When
kickdown
is

performed
the

rod

operates
Ihe

is
de

pressed
downward
and
the

circuit

from

Line

opposes

the

Notes

a
In

checking
oil

level
use

special

paper
cloth
to
handle
the
level

gauge
and
be
careful
not
to
let
the

scraps
of

paper
and
cloth
stick
to

the

gauge

b
Insert
the

gauge
fully
and
take
it

out

quickly
before

splashing
oil

adheres
to
the

gauge
Then
observe

the
level

c
Use
automatic
transmission
fluid

having
DEXRON
identifications

only
in
the
3N71B
automatic
trans

mission

d

Pay
attention
because
the
oil
to
be

used
differs
from
that
used

OF
OIL
LEAKAGE

When
oil

leakage
takes

place
the

portion
near
the

leakage
is
covered

with
oil

presenting
difficulty
in

detecting
the

spot
Therefore
the

places
where
oil

and

gaskets
are

equipped
are
enumerated

leaka
le
proceed
as
follows

Place
the
vehicle
in

a

pit
and

by

sampling
the
leaked
oil
determine
if
it

is
the

torque
converter
oil
The

torque

converter
oil
has
a
color
like

So
it
is

easily

distinguished
from

and

shift
the

to
increase

the

The

will
then
be

found
more

easily

Note
As
oil

leakage
from

does
not

except
when

running
at

it
is

impos

to
locate
