DISASSEMBLY AND ASSEMBLY (Continued)

(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.

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.

TRANSMISSION

DISASSEMBLY

(1) Clean exterior of transmission with suitable

solvent or pressure washer.

(2) Place transmission in vertical position.
(3) Measure and record the input shaft end-play

measurement.

(4) Remove throttle and shift levers from valve

body manual shaft and throttle lever shaft.

(5) Remove transmission oil pan and gasket.
(6) 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.

(7) Remove park/neutral position switch and seal.
(8) 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.

(9) Remove valve body assembly. Push valve body

harness connector out of case. Then work park rod
and valve body out of case (Fig. 150).

(10) Remove accumulator outer spring, piston and

inner spring (Fig. 151). Note position of piston and
springs for assembly reference. Remove and discard
piston seals if worn or cut.

(11) Remove pump oil seal with suitable pry tool or

slide-hammer mounted screw.

DISASSEMBLY AND ASSEMBLY (Continued)

(12) Remove front band lever pin access plug (Fig.

152). Use square end of 1/4 in. drive extension to
remove plug as shown.

(13) Remove oil pump and reaction shaft support

assembly as follows:

(a) Tighten front band adjusting screw until

band is tight around front clutch retainer (Fig.
153). This will prevent retainer from coming out
with pump and possibly damaging clutch or pump
components.

(b) Remove oil pump bolts.
(c) Thread Slide Hammer Tools C-3752 into

threaded holes in flange of oil pump housing (Fig.
154).

(d) Remove oil pump and reaction shaft support

by bumping slide hammers outward alternately to
pull pump from case (Fig. 155).
(14) Remove oil pump gasket (Fig. 156). Note gas-

ket position in case for assembly reference.

(15) Loosen front band adjusting screw until band

is completely loose.

(16) Remove front band strut and anchor (Fig.

157).
