(12) Install throttle valve and spring.
(13) Install kickdown valve and detent.
(14) Install pressure regulator valve.
(15) Install switch valve.
(16) Position adjusting screw bracket on valve
body. Align valve springs and press bracket into
place. Install short, upper bracket screws first and
long bottom screw last. Verify that valve springs and
bracket are properly aligned. Then tighten all three
bracket screws to 4 N·m (35 in. lbs.) torque.
(17) Perform Line Pressure and Throttle Pressure
adjustments. Refer to adjustment section of this
group for proper procedures.
(18) Lubricate solenoid case connector O-rings and
shaft of manual lever with light coat of petroleum
jelly.
(19) Attach solenoid case connector to 3-4 accumu-
lator with shoulder-type screw. Connector has small
locating tang that fits in dimple at top of accumula-
tor housing (Fig. 146). Seat tang in dimple before
tightening connector screw.
(20) Install solenoid assembly and gasket. Tighten
solenoid attaching screws to 8 N·m (72 in. lbs.)
torque.
(21) Verify that solenoid wire harness is properly
routed (Fig. 147). Solenoid harness must be clear
of manual lever and park rod and not be
pinched
between
accumulator
housing
and
cover.

DISASSEMBLY AND ASSEMBLY (Continued)
GOVERNOR BODY, SENSOR AND SOLENOID
(1) Turn valve body assembly over so accumulator
side of transfer plate is facing down.
(2) Install new O-rings on governor pressure sole-
noid and sensor.
(3) Lubricate solenoid and sensor O-rings with
clean transmission fluid.
(4) Install governor pressure sensor in governor
body.
(5) Install governor pressure solenoid in governor
body. Push solenoid in until it snaps into place in
body.
(6) Position governor body gasket on transfer
plate.
(7) Install retainer plate on governor body and
around solenoid. Be sure solenoid connector is posi-
tioned in retainer cutout.
(8) Align screw holes in governor body and trans-
fer plate. Then install and tighten governor body
screws to 4 N·m (35 in. lbs.) torque.
(9) Connect harness wires to governor pressure
solenoid and governor pressure sensor.
(10) Install fluid filter and pan.
(11) Lower vehicle.
(12) Fill transmission with recommended fluid and
road test vehicle to verify repair.

DISASSEMBLY
(1) Clean transmission exterior with steam gun or
with solvent. Wear eye protection during cleaning
operations.
(2) Place transmission in a vertical position.
(3) Measure and record input shaft end play read-
ings.
(4) Remove shift and throttle levers from valve
body manual lever shaft.
(5) Place transmission in horizontal position.
(6) Remove transmission oil pan and gasket.
(7) Remove filter from valve body (Fig. 148). Keep
filter screws separate from other valve body screws.
Filter screws are longer and should be kept with fil-
ter.
(8) Remove park/neutral position switch.
(9) Remove hex head bolts attaching valve body to
transmission case (Fig. 149). A total of 10 bolts are
used. Note different bolt lengths for assembly refer-
ence.
(10) Remove valve body assembly. Push valve body
harness connector out of case. Then work park rod
and valve body out of case (Fig. 150).
(11) Remove accumulator piston and inner and
outer springs (Fig. 151).
(12) Remove pump oil seal with suitable pry tool
or slide-hammer mounted screw.
(13) Loosen front band adjusting screw locknut 4-5
turns. Then tighten band adjusting screw until band
is tight around front clutch retainer. This prevents
front/rear clutches from coming out with pump and
possibly damaging clutch or pump components.
(14) Remove oil pump bolts.
(15) Thread bolts of Slide Hammer Tools C-3752
into threaded holes in pump body flange (Fig. 152).
