(11) Check seal ring on rear clutch retainer hub
and seal rings on input shaft (Fig. 43). Also verify
that shaft seal rings are installed in sequence shown.
(12) Install rear clutch thrust washer (Fig. 44).
Use additional petroleum jelly to hold washer in
place if necessary.
(13) Align clutch discs in front clutch and install
front clutch on rear clutch (Fig. 45). Rotate front
clutch retainer back and forth until completely
seated on rear clutch retainer.
(14) Coat intermediate shaft thrust washer with
petroleum jelly. Then install washer in rear clutch
hub (Fig. 46). Use enough petroleum jelly to holdwasher in place. Be sure grooved side of washer faces
rearward (toward output shaft) as shown. Also note
that washer only fits one way in clutch hub. Note
thickness of this washer. It is a select fit part and is
used to control transmission end play.

(15) Align drive teeth on rear clutch discs with
small screwdriver (Fig. 47). This makes installation
on front planetary easier.
(16) Raise front end of transmission upward as far
as possible and support case with wood blocks. Front/
rear clutch and oil pump assemblies are easier to
install if transmission is as close to upright position
as possible.
(17) Slide front band into case.
(18) Install front and rear clutch units as assembly
(Fig. 48). Align rear clutch with front annulus gear
and install assembly in driving shell. Be sure output
shaft thrust washer and thrust plate are not dis-
placed during installation.
(19) Carefully work assembled clutches back and
forth to engage and seat rear clutch discs on front
annulus gear. Also be sure front clutch drive lugs are
fully engaged in slots of driving shell after installa-
tion.
(20) Assemble front band strut.
(21) Install front band adjuster, strut and adjust-
ing screw (Fig. 49).
(22) Tighten band adjusting screw until band just
grips clutch retainer. Verify that front/rear clutches
are still seated before continuing.

(23) Check seal rings on reaction shaft support
hub. Verify that seal rings are hooked together and
that front clutch thrust washer is properly positioned
(Fig. 50). Use petroleum jelly to hold thrust washer
in place if necessary.
(24) Lubricate oil pump body seal with petroleum
jelly. Lubricate pump shaft seal lip with petroleum
jelly.
(25) Thread two Pilot Stud Tools C-3288-B into
bolt holes in oil pump bore flange (Fig. 51).
(26) Align and install oil pump gasket (Fig. 51).(27) Install oil pump (Fig. 52). Align and position
pump on pilot studs. Slide pump down studs and
work it into front clutch hub and case by hand. Then
install 2 or 3 pump bolts to hold pump in place.
(28) Remove pilot stud tools and install remaining
oil pump bolts. Tighten bolts alternately in diagonal
pattern to 20 N´m (15 ft. lbs.).
(29) Measure input shaft end play (Fig. 53).
NOTE: If end play is incorrect, transmission is
incorrectly assembled, or the intermediate shaft
thrust washer is incorrect. The intermediate shaft
thrust washer is selective.
(a) Attach Adapter 8266-6 to Handle 8266-8.
(b) Attach dial indicator C-3339 to Handle
8266-8.
(c) Install the assembled tool onto the input
shaft of the transmission and tighten the retaining
screw on Adapter 8266-6 to secure it to the input
shaft.
(d) Position the dial indicator plunger against a
flat spot on the oil pump and zero the dial indica-
tor.
(e) Move input shaft in and out and record read-
ing. End play should be 0.56-2.31 mm (0.022-0.091
in.). Adjust as necessary.
(30) Install accumulator piston and inner and
outer springs (Fig. 54).
(31) Verify that valve body solenoid harness is
secured in 3-4 accumulator housing cover plate.
(32) Install valve body as follows:

(a) Align and carefully insert park rod into pawl.
Rod will make click noise as it enters pawl. Move
rod slightly to check engagement.
(b) Align and seat valve body on case. Be sure
manual lever shaft and overdrive connector are
fully seated in case. Also be sure valve body wiring
is not pinched or kinked.
(c) Install and start all valve body attaching
bolts by hand. Then tighten bolts evenly, in a diag-
onal pattern to 12 N´m (105 in. lbs.) torque. Do not
overtighten valve body bolts. This could result in
distortion and cross leakage after installation.
CAUTION: It is possible for the park rod to displace
into a cavity just above the pawl sprag during
installation. Make sure the rod is actually engaged
in the pawl and has not displaced into the cavity.
(33) Install new filter on valve body. Tighten filter
screws to 4 N´m (35 in. lbs.).
(34) Adjust front and rear bands.
(35) Install seal on park/neutral position switch.
Then install and tighten switch to 34 N´m (25 ft.
lbs.).
(36) Install magnet in oil pan. Magnet goes on
small protrusion at corner of pan.
(37) Position new oil pan gasket on case and
install oil pan. Tighten pan bolts to 17 N´m (13 ft.
lbs.).
(38) Install new valve body manual shaft seal in
case (Fig. 55). Lubricate seal lip and manual shaft
with petroleum jelly. Start seal over shaft and into
case. Seat seal with 15/16 inch, deep well socket.
(39) Install throttle valve and shift selector levers
on valve body manual lever shaft.

INSTALLATION
(1) Check torque converter hub and hub drive
notches for sharp edges burrs, scratches, or nicks.
Polish the hub and notches with 320/400 grit paper
and crocus cloth if necessary. The hub must be
smooth to avoid damaging pump seal at installation.
(2) Lubricate pocket in the rear oil pump seal lip
with transmission fluid.
(3) Lubricate converter pilot hub of the crankshaft
with a light coating of MopartHigh Temp Grease.
(4) Align and install converter in oil pump.
(5) Carefully insert converter in oil pump. Then
rotate converter back and forth until fully seated in
pump gears.
(6) Check converter seating with steel scale and
straightedge (Fig. 56). Surface of converter lugs
should be 1/2 in. to rear of straightedge when con-
verter is fully seated.
(7) Temporarily secure converter with C-clamp.
(8) Position transmission on jack and secure it
with chains.
(9) Check condition of converter driveplate.
Replace the plate if cracked, distorted or damaged.
Also be sure transmission dowel pins are seated
in engine block and protrude far enough to
hold transmission in alignment.
(10) Raise transmission and align converter with
drive plate and converter housing with engine block.
(11) Move transmission forward. Then raise, lower
or tilt transmission to align converter housing with
engine block dowels.(12) Carefully work transmission forward and over
engine block dowels until converter hub is seated in
crankshaft.
(13) Install bolts attaching converter housing to
engine.
(14) Install rear support. Then lower transmission
onto crossmember and install bolts attaching trans-
mission mount to crossmember.
(15) Remove engine support fixture.
(16) Install crankshaft position sensor. (Refer to 14
- FUEL SYSTEM/FUEL INJECTION/CRANKSHAFT
POSITION SENSOR - INSTALLATION)
(17) Install new plastic retainer grommet on any
shift linkage rod or lever that was disconnected.
Grommets should not be reused. Use pry tool to
remove rod from grommet and cut away old grom-
met. Use pliers to snap new grommet into lever and
to snap rod into grommet at assembly.
(18) Connect gearshift and throttle cable to trans-
mission.
(19) Connect wires to park/neutral position switch,
transmission solenoid(s) and oxygen sensor. Be sure
transmission harnesses are properly routed.
CAUTION: It is essential that correct length bolts be
used to attach the converter to the driveplate. Bolts
that are too long will damage the clutch surface
inside the converter.
(20) Install torque converter-to-driveplate bolts.
On models with 10.75 in. converter, tighten bolts to
31 N´m (270 in. lbs.). On models with 12.2 in. con-
verter, tighten bolts to 47 N´m (35 ft. lbs.).
(21) Install converter housing access cover.
(22) Install starter motor and cooler line bracket.
(Refer to 8 - ELECTRICAL/STARTING/STARTER
MOTOR - INSTALLATION)
(23) Connect cooler lines to transmission.
(24) Install transmission fill tube. Install new seal
on tube before installation.
(25) Install exhaust components.
(26) Align and connect propeller shaft. (Refer to 3 -
DIFFERENTIAL & DRIVELINE/PROPELLER
SHAFT/PROPELLER SHAFT - INSTALLATION)
(27) Adjust gearshift linkage and throttle valve
cable if necessary.
(28) Lower vehicle.
(29) Fill transmission with MopartATF +4, type
9602, Automatic Transmission fluid.
