In

these
cases
the

transmission
must

be

repaired

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

INSPECTION

OF
OIL
LEAKAGE

When
oil

leakage
takes

place
the

portion
near
the

leakage
is
covered

with
oil

presenting
difficulty
in

detecting
the

spot
Therefore

places
where
oil

and

are

equipped
are
enumerated

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

Raise

the

and

shift
the

to
increase

the

The

will
then
be

found
more

easily

Note
As

it
is

impos

JUDGEMENT

High

If
the

engine
revolution
in

condition
is

higher
than
the
standard

values
it

indicates
that
one

or
more

clutches
in

the
transmission
are

slipping
and
therefore
no

is

required

For

To

determine

a

test
is
nceded

If

properly
the

Otherwise
the

Slipping
of

is

diffi

cult
to
ascertain

However
if
it

occurs
