HYDRAULIC

The

the

pressure

system

the

pressure

and
the
friction

PRESSURE
SUPPLY
SYSTEM

The

pressure
supply
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

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

For

a
restrictive
orifice

slows
the

while
the

allowed
to

This

prevents
a

Under
