CONTROL

assembly
consists

of

many

precision
parts
and

requires

extreme
care
when
it
has

to
be
re

moved
and
serviced
It
is

good

practice

to

place
parts
in
a

part
rack
so
that

they
can
be
reassembled
in

valve

body

in

their

proper
positions
Added
care

should
also
be
exercised

to

prevent

springs
and
other
small

parts
from

being
sca
ttered
and
lost

Before

assembly

dip
all

parts
in

clean
automatic
transmission

fluid
and

check
to
be
certain

that

they
are
free

of

lint
and
other
minute

particles
If

is
burnt
or
if

the

should
be

This
is

an

easy
and
effective

trouble

shooting
procedure
since
some

changes
in

oil
condition
are
often

linked
with

developed
troubles
For
instance

Lack
of
oil
causes
defective

opera

tion

by

making
the
clutches
and

brakes

slip
resulting
in

severe
wear

This
is

because
the
oil

pump
sucks

air

causing
oil

foaming
thus

rapidly

deteriorating
the
oil

quality
and

pro

ducing
sludge
and
varnish

Excessive
oil
is
also
bad
because
of

oil

foaming
caused

by
the

gears
stirring

up
the
oil

During

high
speed
driving

excessive
oil
in

the
transmission

often
