DIAGNOSIS
A
s
no repair
operation
is,at pres ent,
allowed on
the
automa
tic transr.li
ssion
,
with
the exception
of
the operations
indicated
under chapter
F4/VII,
operators
must
distinguish
between
the faults
resu
lting
from:
a poor adjustment,
• th
e
torque converter,
the
automatic
gear box.
Checking the
brake engine
speed
provides a
promp
t
diagnosis
of
those faults
wh
ich are
attributable
either to the
torque
converter
or to the
gear
box
.
Prior to
r emoving the
gear
box-
converter
assemb
l
y
,
it is essential
that
the following should
b
e che
cked:
• gear
box oil
l evel,
• engine
setting,
•
kick down linkage
adju stment,
• adjustme:r1t
of
s
e

e
ction
system
,
•
adjustment
of bands,
•
brake
engine speed.

Brake engine speed
Caution:
during this test, there should
be
no
one
in
front
of the car.
The
brake test consists
in
finding out
the
engine
speed
as
obtained in D position with throttle wide
open.
This
test
is
designed to check
the correct
op
era
tion of the
converter
reactor,
and of
t
he
gear box
clutches.
Before
this
test,
check
oil level,
and bring
engine to its nonnal op erating temperature.
Apply
vehicle brakes.
Do not
pursue
test
beyond t
ime
required
to
obtain
the
r esult, nor, in
any
case, beyond
5
seconds
per test.
If the test must be r
epea
ted, run
engine for 20
seconds at
1000 r.p.
m
,
in neutral,
to cool
transmission down.

The
acceptable
brake engine speed is
between 1900

If

is higher
than
the standard
speed by more
