VALVE BODY CLEANING AND INSPECTION
The only serviceable valve body components are:
²park lock rod and E-clip
²switch valve and spring
²pressure adjusting screw bracket
²throttle valve lever
²manual lever
²manual lever shaft seal, washer, E-clip and detent
ball
²fluid filter
²converter clutch solenoid
The remaining valve body components are serviced
only as part of a complete valve body assembly.
Clean the valve body components in a parts clean-
ing solution only. Do not use gasoline, kerosene, orany type of caustic solution. Dry the parts with com-
pressed air. Make sure all passages are clean and
free from obstructions.
Do not use rags or shop towels to wipe off
valve body components. Lint from these materi-
als will adhere to the valve body components.
Lint will interfere with valve operation and
may clog filters and fluid passages.
Inspect the throttle and manual valve levers and
shafts. Do not attempt to straighten a bent shaft or
correct a loose lever. Replace these components if
worn, bent, loose or damaged in any way.
Inspect all of the valve body mating surfaces for
scratches, nicks, burrs, or distortion. Use a straight-
edge to check surface flatness. Minor scratches may
be removed with crocus cloth using only very light
pressure.
Minor distortion of a valve body mating surface
may be corrected by smoothing the surface with cro-
cus cloth. The cloth should be in sheet form and be
positioned on a surface plate, sheet of plate glass, or
equally flat surface. However, if distortion is severe
or any surfaces are heavily scored, the valve body
will have to be replaced.

VALVE BODY ASSEMBLY AND ADJUSTMENT
CAUTION: Do not force valves or plugs into place
during reassembly. If the valve body bores, valves
and plugs are free of distortion or burrs, the valve
body components should all slide into place easily.
In addition, do not overtighten the transfer plate
and valve body screws during reassembly. Over-
tightening can distort the valve body resulting in
valve sticking, cross leakage and unsatisfactory op-
eration. Tighten valve body screws to recom-
mended torque only.
(1) Lubricate valve body bores, valves and plugs
with Mopar ATF Plus transmission fluid.
(2) Insert rear clutch and rear servo check balls in
transfer plate (Fig. 120).
(3) Install filter screen in separator plate (Fig.
120).
(4) Align and install separator plate on transfer
plate. Verify check ball position before installing sep-
arator plate on transfer plate.
(5) Install new O-ring on converter clutch solenoid
and insert solenoid in separator plate (Fig. 120).
Then secure solenoid in position with attaching
screw. Tighten screw to 4 Nzm 35 in. lbs.) torque.
(6) Position valve body so internal passages and
check ball seats are facing upward. Then install
check balls in valve body (Fig. 121). There are a total
of seven check balls; The one large check ball is ap-
proximately 11/32 inch in diameter. The remaining
check balls are approximately 1/4 inch in diameter.
Note that check balls will be steel on some very early
production models and plastic on later production
models.
(7) Align and install assembled transfer and sepa-
rator plates on valve body. Install and tighten valve
body screws alternately in a diagonal pattern to 4
Nzm (35 in. lbs.) torque.
(8) Assemble and install lockup module and compo-
nents on valve body (Fig. 122).
(9) Assemble regulator valve line pressure plug,
sleeve, throttle plug and spring (Fig. 113). Insert as-sembly in valve body and install end plate. Tighten
end plate screws to 4 Nzm (35 in. lbs.) torque.
(10) Install 1-2 and 2-3 shift valves and springs
(Fig. 118).
(11) Install 1-2 shift control valve and spring (Fig.
118)
(12) Install shuttle valve as follows:
(a) Insert shuttle valve in bore.
(b) Insert plastic guides in shuttle valve second-
ary spring.
(c) Install spring on end of valve.
(d) Hold shuttle valve in place. Then compress
secondary spring and install E-clip in groove at end
of valve.
(e) Verify that spring and E-clip are properly
seated before proceeding.
(13) Install shuttle valve cover plate (Fig. 118).
Tighten end plate screws to 4 Nzm (35 in. lbs.)
torque.
(14) Install 1-2 and 2-3 valve governor plugs in
valve body (Fig. 113). Then install shuttle valve pri-
mary spring and throttle plug.

justment must be performed properly and in the cor-
rect sequence. The correct sequence is line pressure
adjustment first and throttle pressure adjustment
last.
Line Pressure Adjustment
Measure distance from the valve body to the inner
edge of the adjusting screw with an accurate steel
scale (Fig. 124).
Distance should be 33.4 mm (1-5/16 in.).
If adjustment is required, turn the adjusting screw
in, or out, to obtain required distance setting.
The 33.4 mm (1-5/16 in.) setting is an approxi-
mate setting. Because of manufacturing toler-
ances, it may be necessary to vary from this
dimension to obtain desired pressure.
One complete turn of the adjusting screw changes
line pressure approximately 1-2/3 psi (9 kPa). Turn-
ing the adjusting screw counterclockwise increases
pressure while turning the screw clockwise decreases
pressure.
Throttle Pressure Adjustment
Insert Gauge Tool C-3763 between the throttle le-
ver cam and the kickdown valve stem (Fig. 125).
Push the gauge tool inward to compress the kick-
down valve against the spring and bottom the throt-
tle valve.
Maintain pressure against kickdown valve spring.
Turn throttle lever stop screw until the screw head
touches throttle lever tang and the throttle lever cam
touches gauge tool.
The kickdown valve spring must be fully com-
pressed and the kickdown valve completely
bottomed to obtain correct adjustment.
TRANSMISSION ASSEMBLY TIPS
Do not allow dirt, grease, or foreign material to en-
ter the case or transmission components during as-
sembly. Keep the transmission case and componentsclean. Also make sure the tools and workbench area
used for assembly are equally clean.
Shop towels used for wiping off your hands and
service tools must be made oflint freematerials.
Lint will adhere to transmission parts and could in-
terfere with valve operation, or even restrict fluid
passages.
Lubricate the transmission components with Mopar
ATF Plus during reassembly. Use Mopar Door-Ease,
or Ru-Glyde on seals and O-rings to ease installation.
Petroleum jelly can also be used to hold thrust
washers and plates in position during assembly oper-
ations. However,do notuse chassis grease, bearing
grease, white grease, or similar lubricants on any
transmission part. These types of lubricants can
eventually block or restrict fluid passages and valve
operation. Use petroleum jelly only.
Do not force parts into place. Most of the transmis-
sion components are easily installed by hand when
properly aligned. If a part seems extremely difficult
to install, it is either misaligned or incorrectly assem-
bled. Also verify that thrust washers, thrust plates
and seal rings are correctly positioned before assem-
bly. These parts can interfere with proper assembly if
mispositioned or ``left out'' by accident.
