When the
selector lever is moved to the low position on the quadrant. the manualvalve is positioned to allow drive oil, intermediate oil and low oil to pass
through the valve. Low oil is directed to the
1 2 shift valve train which acts with the I 2 shift valve spring against governor oil pressure to close off drive
oil from passing into the second clutch passage. At the
same time, low oil is directed to the Reverse and Low control valve and acts against the spring to
allow detent regulated oil at the Reverse and Law control
valve to flow to the 2 3 shift valve, which is bottomed in its bore by intermediate oil pressxeand the valve spring. The detent oil
pazses through the 2 3 shift vahre and into the third clutch oil passages to apply the third clutch and to close off
modulator oil pressure from the 3-2 control valve to the 2 3 shift control valve. Third control oil isalSo directed to the Reverse and Law control
valve.which is held open against its spring by low oil pressure. and closes off the
source of rupply to the servo release pasege. to allow the servo to apply the low
band. Intermediate oil seats the check ball at the Reverse
passage at the presue regulator boost valve cavity and continues to the pressure regulator valve
to increase oil pressure in the circuit.

21. Using a drift on tap, press out oil pump bushing
with arbor press. Use rag or cloth to protect oil pumpface.22. Install new oil pump hub bushing with arbor
press using tool J-23130-1. See Figure
7C-149. Clean
pump body, including all holes and pockets
thoroughly. With oil pump shaft hole “A” facing
downward, scribe an aligning mark on oil pump
shaft inner diameter at the center of the oil groove
to the right of hole “A”. Scribe mark on outer edge
of bushing through the centers of the small and large
drilled holes “B”. Place bushing into oil pump shaft
with small hole up, and align scribe marks on bush-
ing with those made in oil pump shaft. Use arbor
press to drive bushing into oil pump shaft until
seated in the bore. Care must be taken so that bush-
ing is pressed in straight, using the scribe marks as
a guide until firmly seated.
23. Inspect and thoroughly clean the pressure regula-
tor and priming valve assemblies. Immerse all valves
in transmission fluid before installing in bores.
24. Install pressure regulator valve in oil pump body
bore. See Figure
7C-150.25. Install pressure regulator valve, two spring seats,
spring, boost valve and sleeve in oil pump body bore.
26. Depress pressure regulator boost valve sleeve un-
til backend lines up with pin hole and insert pin to
XWP$.27. Install priming valve assembly from front face of
pump. Priming valve retainer should be pressed in
flush with surface of oil pump body. See Figure 7C-
151.28. Inspect oil pump hub oil seal rings. Replace if
damaged or side wear is noted. See Figure
7C-152.29. Inspect reverse clutch piston for damage, Re-
place if necessary.

12. Inspect the piston return springs. Evidence of
extreme heat or burning in the area of the clutch may
have caused the springs to take a heat set and would
justify replacement of the springs.

wear.14. If necessary, remove second clutch hub bushing
using remover and installer J-23130-6 with driver

Install new second clutch hub bushing using tool
J-23 130-6 and driver handle J-8092. Bushing must be
driven in until tool bottoms on bench. See Figure 7C-
164.16. To install second clutch piston into second clutch
drum, use installer tool J-23080 so as not to damage
lip seal. See Figure 7C-165. Use liberal amount of
transmission fluid for ease of installation and to pre-
vent seal damage.

19. Using spring compressor tool J-2590-12 with
adapter J-21420-1 on retaining seat, compress sec-
ond clutch piston return springs. Care should be
taken so that retainer does not catch in snap ring
groove and damage retainer.
20. Install snap ring with snap ring pliers such as

in the slot of the second clutch hub. Secure with
petroleum jelly (unmedicated).
22. Inspect condition of composition and steel plates.
Do not diagnose a composition drive plate by co/or.
A. Dry composition plates with compressed air and
inspect the composition surface for:
1. Pitting and flaking
2. Wear
3. Glazing

enough to close the valve and stop the flow of refrig-
erant liquid.
For the sake of simplicity, we have described the
float and valve action as being in a sort of definite
wide open or tight shut condition. Actually, though,
the liquid level falls rather slowly as the refrigerant
boils away. Likewise, the float goes down gradually
and gradually opens the valve just a crack. New
refrigerant liquid barely seeps in through the
“cracked” valve. At such a slow rate of flow, it raises
the liquid level in the evaporator very slowly.
With that in mind, it is easy to see how it would be
possible for a stabilized condition to exist. By that,
we mean a condition wherein the valve would be/

W-16opened barely enough to allow just exactly the right
amount of refrigerant liquid to enter the freezer to
take the place of that leaving as a vapor.
Thermostatic Expansion ValveAutomotive air conditioning systems use a thermo-
static expansion valve in place of the float system.
Figure 9B-18 shows a cross-section of the valve
which consists primarily of the gas-filled power ele-
ment, body, actuating pins, seat and orifice. At the
high pressure liquid inlet is a tine mesh screen which
prevents dirt, tilings or other foreign matter from
entering the valve orifice.
When the valve is connected in the system, the high
pressure liquid refrigerant enters the valve through
the screen from the receiver-dehydrator (which acts
as a storage tank for the condensed refrigerant as it
leaves the condenser) and passes on to the seat and
orifice. Upon passing through the orifice the high
pressure liquid becomes low pressure liquid. The low
pressure liquid leaves the valve and flows into the
evaporator core where it absorbs heat from the
evaporator core and changes to a low pressure vapor,
and leaves the evaporator core as such. The power
element bulb is clamped to the low pressure vapor
line just beyond the outlet of the evaporator (Fig.
9B-20).The operation of the valve is quite simple. It is a
matter of controlling opposing forces produced by a
spring and the refrigerant pressures. For example:
The pressure in the power element is trying to push
the seat away from the orifice, while the spring is
trying to force the seat toward the orifice. These
opposing pressures are established in the design of
the valve so that during idle periods, i.e. when the
system is not operating, the spring force and the
refrigerant pressure in the cooling coil are always
