First

make

In

most
cases
this

occurs
when

or
when

faulty
In

this

case
the

cannot
be
correct

by

replacing

and
therefore

trouble
shoot

ing
must
be
carried
out

carefuDy
It
should

also
be

noted
that

gear

slips
out

due

to

Noise

When

occurs
with

idling
and

ceases
when

disengaged
or
when

noise
occurs
while

it
is

an

indication
that

HYDRAULIC

The

the

pressure

and
the

PRESSURE
SUPPLY
SYSTEM

The

pressure

system
consists

of

a

gear

type
oil

pwnp
driven

by
the

engine
through
the

The

Governor

valve

The

governor
valve
transmits

re

gulated
pressure
based
on
car

peed

to
the

shift
valves
to
control

upshifts

and
downshifts

Vacuum
throttle
valve

The
vacuum

throttle
valve
transmits

regulated
pressure
based
on

engine

load
vacuum
This

pressure
controls

the

pressure
regulator
valve

Also
this

pressure
is

applied
to
one
end
of
the

shift
valves
in

opposition
to

governor

pressure
which
acts

on
the
other

end

of
the
shift

controlling

upshift

For

a
restrictive

slows
the

while
the

is
allowed
to

This

prevents
a

Under

heavy

however
the

therefore
a
