Early production models will have the type 2 fit-
ting used previously. This fitting requires a release
tool to disconnect the cooler line from the fitting (Fig.
29). Later production models will have a new style
fitting that does not require any type of release tool.
This fitting has a plastic insert with built-in release
tabs (Fig. 30).
Cooler Line And Fitting Service
The cooler lines and fittings are only serviceable as
assemblies. Damaged fittings or cooler lines are to be
replaced. Fittings swedged into cooler line hoses (Fig.
31) are serviced only as part of the entire cooler hose.
DISCONNECTING COOLER LINES WITH TYPE
2 FITTING
(1) If fitting and cooler line are encrusted with
dirt, mud, or grease, clean fitting and cooler line with
Mopar spray type carburetor or brake cleaner. Plastic
release tool will not fit into retainer clip if fitting is
full of foreign material.
(2) Slide small plastic release tool into fitting until
tool bottoms against cooler line flange (Fig. 29).
(3) Push and turn release tool to spread retainer
clip and pull cooler line out of fitting (Fig. 29).
(4) Cover open ends of cooler lines and fittings to
prevent dirt entry.
(5) Inspect condition of fitting. Replace transmis-
sion fitting as an assembly if fitting body or retainerclip is damaged. Replace cooler line as assembly, if
fitting swedged into cooler line hose, is damaged.
DISCONNECTING COOLER LINES WITH NEW
STYLE FITTING
The new style fittingdoes notrequire any kind of
release tool. The fitting inserts have built-in release
tabs that only require finger pressure to release
them.
The new style fitting insert is unique. The insert
does not stay in place inside the fitting when re-
leased. Instead, the insert remains on the line and
does not have to be removed.
To release a new style fitting, simply squeeze the
insert tabs (Fig. 32) and disconnect the line. The in-
sert will remain in place on the line, or fitting and
does not have to be removed (Fig. 33).

CONNECTING COOLER LINES AND FITTINGS
(ALL TYPES)
(1) Wipe cooler line and fitting clean with shop
towel.
(2) Insert cooler line into fitting. Then push line
inward until retainer or insert secures line. A snap or
click sound will be heard when the insert tabs or re-
tainer clip seats behind the cooler line flange.
(3)Pull outward on cooler lines/fittings to
verify they are properly secured.
CAUTION: The wire retainer clips or insert release
tabs secure the cooler lines. If the clips or tabs are
deformed, distorted, or not fully seated, normal
fluid pressure could unseat the lines resulting in
fluid loss and transmission damage. Be very sure
the cooler lines are firmly secured as described in
step (3).
CONVERTER DRAINBACK CHECK VALVE SERVICE
The converter drainback check valve is located in
the cooler outlet (pressure) line near the radiator
lower tank. The valve prevents fluid drainback when
the vehicle is parked for lengthy periods. The valve
check ball is spring loaded and has an opening pres-
sure of approximately 2 psi. Refer to the cooler flow
test procedure for valve testing.
The valve is serviced as an assembly; it is not re-
pairable. Do not clean the valve if restricted, or con-
taminated by sludge, or debris. If the valve fails, or if
a transmission malfunction occurs that generates
sludge and/or clutch particles and metal shavings,
the valve must be replaced.
The valve must be removed whenever the cooler
and lines are reverse flushed. The valve can be flow
tested when necessary. The procedure is exactly the
same as for flow testing a cooler.
If the valve is restricted, installed backwards, or in
the wrong line, it will cause an overheat condition
and possible transmission failure.
CAUTION: The drainback valve is a one-way valve.
As such, it must be properly oriented in terms of
flow direction. In addition, the valve must only beinstalled in the pressure line. Otherwise flow will be
blocked causing overheat and eventual transmis-
sion failure.
TRANSMISSION COOLER FLOW TESTING
The transmission main and auxiliary coolers, plus
the drainback valve, should be flow tested whenever
fluid overheating is noted.
Restricted flow caused by contamination, or a
cooler malfunction, reduces lubrication fluid flow
throughout the transmission. This can result in fluid
overheating, fluid breakdown, bushing wear, shift
problems and component failure.
Normal color of transmission fluid varies from
bright red, to light pink. Fluid overheating is indi-
cated when fluid color ranges from orange-brown to
black, and the fluid smells burned, or contains
sludge.
CAUTION: If a transmission malfunction contami-
nates the fluid with clutch disc and metal particles,
the cooler and lines must be reverse flushed thor-
oughly. Flushing will prevent sludge and particles
from flowing back into the transmission and con-
verter after repair.
Cooler flow is tested by measuring the amount of
fluid pumped through the cooler in a specified time
by the transmission oil pump.The same flow test
procedure is used for the drainback valve, main
cooler, and auxiliary cooler.
Cooler And Drainback Valve Flow Test Procedure
(1) Test flow throughdrainback valveas follows:
(a) Add extra quart of ATF Plus to transmission.
(b) Disconnect pressure line at radiator fitting, or
at drainback valve and position hose or valve end
in one quart test container.
(c) Shift transmission into neutral, run engine at
idle speed for 20 seconds, and note flow from valve.
Use stopwatch to check test time.
(d) Replace drainback valve if flow is less than
one quart in 20 seconds, is intermittent, or does
not flow at all.
(e) Connect pressure hose to radiator fitting and
proceed to cooler flow test.
(2) Test flow throughmain cooleras follows:
(a) Disconnect cooler return (rear) line at trans-
mission and place it in one quart test container.
(b) Add extra quart of fluid to transmission.
(c) Shift transmission into neutral, run engine at
idle speed for 20 seconds, and note flow from valve.
Use stopwatch to check test time.
(d) Replace cooler if fluid flow is less than one
quart in 20 seconds, is intermittent, or does not
flow at all.

Replace the clutch discs if warped, worn, scored,
burned or charred, or if the facing is flaking off. Re-
place the steel plates if heavily scored, warped, or
broken. Be sure the driving lugs on the plates are in
good condition. The lugs must not be bent, cracked or
damaged in any way.
Replace the clutch spring and spring retainer if ei-
ther is distorted, warped or broken.
Check the lug grooves in the clutch retainer. The
steel plates should slide freely in the slots. Replace
the retainer if the grooves are worn or damaged.
Check action of the check ball in the retainer (Fig.
64). The ball must move freely and not stick.
Inspect the front clutch retainer bushings
carefully (Fig. 65). The retainer bushings are
not serviceable. It will be necessary to replace
the retainer if either bushing is scored, or
worn.
Inspect the piston and retainer seal surfaces for
nicks or scratches. Minor scratches can be removed
with crocus cloth. However, replace the piston and/or
retainer if the seal surfaces are seriously scored.FRONT CLUTCH ASSEMBLY
(1) Soak clutch discs in transmission fluid while
assembling other clutch parts.
(2) Install new seals on piston and in hub of re-
tainer. Be sure lip of each seal faces interior of clutch
retainer.
(3) Lubricate lips of piston and retainer seals with
liberal quantity of Mopar Door Ease, or Ru-Glyde.
Then lubricate retainer hub, bore and piston with
light coat of transmission fluid.
(4) Install clutch piston in retainer (Fig. 66). Use
twisting motion to seat piston in bottom of retainer. A
thin strip of plastic (about 0.0209thick), can be used
to guide seals into place if necessary.
CAUTION: Never push the clutch piston straight in.
This will fold the seals over causing leakage and
clutch slip. In addition, never use any type of metal
tool to help ease the piston seals into place. Metal
tools will cut, shave, or score the seals.
(5) Position spring in clutch piston (Fig. 67).
(6) Position spring retainer on top of piston spring
(Fig. 68).Make sure retainer is properly in-
stalled. Small raised tabs should be facing up-
ward. Semicircular lugs on underside of
retainer are for positioning retainer in spring.

them. These tabs fit in the holes or slots provided in
each planetary gear.
Inspect the output shaft carefully. Pay particular
attention to the machined bushing/bearing surfaces
on the shaft and the governor valve shaft bore at the
shaft rear.
Replace the output shaft if the machined surfaces
are scored, pitted, or damaged in any way. Also re-
place the shaft if the splines are damaged, or exhib-
it cracks at any location (especially at the governor
valve shaft bore).
The annulus gears can be removed from their sup-
ports if necessary. Just remove the snap rings and sep-
arate the two parts when replacement is necessary. In
addition, the annulus gear bushings can be replaced if
severely worn, or scored. However it is not necessary to
replace the bushings if they only exhibit normal wear.
Check bushing fit on the output shaft to be sure.
ASSEMBLING PLANETARY GEARTRAIN
(1) Lubricate output shaft and planetary components
with transmission fluid. Use petroleum jelly to lubricate
and hold thrust washers and plates in position.
(2) Assemble rear annulus gear and support if dis-
assembled. Be sure support snap ring is seated and
that shoulder-side of support faces rearward (Fig.
85).(3) Install rear thrust washer on rear planetary
