If
the

engine
levolulion
in

condi
ion
is

higher
than
the
standard

values
it
indicates

that
onc
or
more

clutches
in
the

transmission
are

slipping
and
therefore
no

further

is

required

For

slipping

To

determine
which
is

slipping

front

clutch
or
low
and
reverse

brake

a
road

test
is

needed

If
while

coasting
after

starting

with
the
levcr
in
I

range
engine

braking
does
not

work

properly
the

low

and
reverse
brake
is

slipping

Otherwise
the
front
clutch
is

slipping

Slipping
of
the
band
brake
is
diffi

cuJt
to
ascertain

However
jf
it

occurs

with

the
lever
in
1

range
engine

AT
41
revolution
increases

up
to
the
same

level

as
in
1st

range
It

is

impossible

to

check
it
in
the

stall
test

2
Standard
stall
rnoluiion

If
the

engine
revoluiion
in

stall

ondition
is
within

he
standard

values
the
control
elements
are

nOf

mally

operating
in

the

ranges
D

I

and
R

Also
the

engine
and
one

clutch
of
the

torque
converter
are

norinal
in

performance
and

operation

The

one

clutch

of
the

torque

converter

however
sometimes

sticks

This
is
determined

in
the
road

test

Lower

stall
revolution

If

the

engine

in

condition
is

than
the

standard

values
it

indicates
that
the

engine
is
in

abnormal

condition

If

the

is

poor
until
vehicle

speed
of

mately
SO

30

is
attained

and
then
normal

beyond
that

speed
it

can
be

that

In
such

a

case
the

rises

abnormally
and
so

special
care
is

required

3
If
the

transmission
does

it

indicates

poor

performance

ROAD

TEST

An

accurate

knowledge
of
the
au
to

matic

transmission
is

required
for
an

exact

diagnosis

II
is

recommended
that
a

diagnosis

guide
chart
with
the
standard

vehicle

speeds
for
each

stage
of

the

up
and

down

shiftings
be

prepared
Measured

vehicle

speeds
are
to

be
filled
in

the

adjoining
column
after
each

testing

Also
it

is
advisable
to

mount

a

stopper
for

positioning
the
throttle

The

by

The

a

and
it

prevents

except
when
the

at

is

higher

than
at
