HYDRAULIC
CONTROL
UNIT
AND

VALVES

The

hydraulic
or
a
tomatic
control

system
is

comprised
of
four
4
basic

groups
the

pressure
supply
system

the

pressure
regulating
system
the

flow
control
valves
and
the
friction

elements

PRESSURE
SUPPLY
SYSTEM

The

pressure
supply
system
consists

of

a

gear

type
oil

pwnp
driven

by
the

engine
through
the

torque
converter

The

pump
provides

pressure

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
valves

controlling

upshift

and
downshift

speeds

Tlmlnll
valve

For
2
3
shifts
a
restrictive
orifice

slows
the

application
fluid
to
the
front

clutch
while
the

slower

reacting
band

is
allowed
to
release
This

prevents
a

hard
2
3
or
3
2
shift
Under

heavy

load
however
the

engine
will
tend
to

run

away
during
the
2
3

or
3
2

pause
therefore
a
2

valve

using
throttle
and

governor

pressure
is

used
to

bypass
the

restrictive
orifice

during
such

heavy

conditions

Solenoid

valve

The
solenoid
downshift

is
