It
is

desirable
that
the

repair

operations
are
carried
out
in
the

dust

Due
to
the
differences
of
the

engine
capacities
the

specifications
of

component
parts
for
each

model

may
be

different
How

ever

they
do
have
common

adJust

ments
and

as
well

as

During
the

repair
operations

refer
to
the
Service
Data
and

Specifi

cations
section
for
the

4
Before

removing
any
of
subas

semblies

thoroughly
clean
the

outside

of

wash
all

clean
and
examine

Inspecting
oil
condition

The
condition
of
oil

sticking
to
the

level

gauge
indicates
whether
to
over

haul
and

repair
the
transmission

or

look

for
the

defective

part

If
the

oil
has
deteriorated
into

a

varnish
like

quality
it

causes
the
con

trol
valve
to

stick
The
blackened
oil

gives
the

proof
of
the
burned
clutch

brake
band

etc
In

these
cases
the

transmission
must
be

replaced

Notes
a
In

use

special

not

When

To

exactly
locate

the

place
of
oil

leakage
proceeds
as
follows

Place
the

vehicle
in
a

pit
and

by

sampling
the

leaked
oil
examine

whe

ther

it
is
the

torq
le
converter
oil
or

not

The

torque
converter
oil

assumes

color
like
red
wine

when

shipped

from
the

factory
so
it
is

ea

ily
distin

guished
from

engine
oil

or

gear
oil

Cleanly
wipe
off
the

leaking
oil
and

dust
and
detect

the

spot
of
oil

leakage

Use
nonflammable

organic
solvent

such
as
carbon

tetrachloride
for

wip

ing

Raise
the

oil

temperature
by

op

erating
the

engine
and

shift
the

lever

to
0
to

heighten
the

oil

pressure

The

spot
of
oil

leakage
will
then

be

found

more

easily

Note

A

the
oil

leakage
from
the

breather
does
not
take

place

except
when

running
at

high

speed
it
is

impossible
to
locate

the

spot
of

leakage
with
vehicle

stalled

Checking
engine

rprn

The

engine
idling
revolution
should

be

properly

adjusted

If
the

engine
revolution
is

too
low

the

engine
does
not

operate
smoothly

and
if

too

high
a

strong
shock
or

creep
develops
when

changing

is

not

properly
or

chang

ing
point
is
too

high
check
the

kick

down

them

When
the

key
is

positioned
at
the

1st

stage

and
the

accelerator

pedal
is

depressed

deeply
the
switch
contact
should
be

closed
and
the

should
click

If

it

does
not
click
it

indicates

a
defect

Then
check

each

part
