DESCRIPTION
The power steering gear is a recirculating ball type
gear (Fig. 1). The gear ratio's used are 12.5:1.
OPERATION
The gear acts as a rolling thread between the
worm shaft and rack piston. The worm shaft is sup-
ported by a thrust bearing at the lower end and a
bearing assembly at the upper end. When the worm
shaft is turned from input from the steering column
the rack piston moves. The rack piston teeth mesh
with the pitman shaft. Turning the worm shaft, turns
the pitman shaft, which turns the steering linkage.
REMOVAL
(1) Place the front wheels in a straight-ahead posi-
tion.
NOTE: The steering column on vehicles with an
automatic transmission may not be equipped with
an internal locking shaft that allows the ignition key
cylinder to be locked with the key. Alternative meth-
ods of locking the steering wheel for service will
have to be used.
(2) Lock the steering wheel.
(3) Siphon out as much power steering fluid as
possible.

(8) Fill the system with fluid and perform Steering
Pump Initial Operation, (Refer to 19 - STEERING/
PUMP - STANDARD PROCEDURE).
(9) Start the engine and run it for fifteen minutes
then stop the engine.
(10) Remove the return line/lines from the pump
and plug the pump port/ports.
(11) Pour fresh fluid into the reservoir and check
the draining fluid for contamination. If the fluid is
still contaminated, then flush the system again.
(12) Install the return line/lines and perform
Steering Pump Initial Operation, (Refer to 19 -
STEERING/PUMP - STANDARD PROCEDURE).
REMOVAL
REMOVAL - GAS
(1) Drain and siphon the power steering fluid from
the reservoir.
(2) Remove the serpentine belt.
CAUTION: Do not remove the fitting on the pump
that the high pressure hose screws into. The fitting
may come loose unless it is backed up using
another wrench. If the fitting does come loose, it
must be retightened before continuing. (57 - 67Nm,
40 - 50 lbft) If this fitting comes out of the pump
body, the internal spring and valve parts will fall out
of the pump and they cannot be reinstalled prop-
erly. If this occurs the pump needs to be replaced
with a new pump.
(3) Disconnect the return hose. (Fig. 2)
(4) Disconnect the pressure hose. (Fig. 2)
(5) Access to remove the three bolts securing the
pump to the cylinder head can be gained thru the
pulley holes. (Fig. 2)

DISASSEMBLY
(1) Clean exterior of transmission with suitable
solvent or pressure washer.
(2) Place transmission in vertical position.
(3) Measure the input shaft end play as follows
(Fig. 17).
(a) Attach Adapter 8266-5 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 8266-5 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. Record the maximum travel for assembly ref-
erence
(4) Remove the overdrive unit from the main
transmission case. If overdrive unit is not to be ser-
viced, install Alignment Shaft 6227-2 into the over-
drive unit to prevent misalignment of the overdrive
clutches during service of main transmission compo-
nents.
(5) Remove throttle and shift levers from valve
body manual shaft and throttle lever shaft.
(6) Remove transmission oil pan and gasket.(7) Remove filter from valve body (Fig. 18). Keep
filter screws separate from other valve body screws.
Filter screws are longer and should be kept with fil-
ter.
(8) Remove the transmission range sensor.
(9) Remove hex head bolts attaching valve body to
transmission case (Fig. 19). A total of 10 bolts are
used. Note different bolt lengths for assembly refer-
ence.

ADJUSTMENTS - THROTTLE VALVE CABLE
A correctly adjusted throttle valve cable will cause
the throttle lever on the transmission to move simul-
taneously with the throttle body lever from the idle
position. Proper adjustment will allow simultaneous
movement without causing the transmission throttle
lever to either move ahead of, or lag behind the lever
on the throttle body.
ADJUSTMENT VERIFICATION
(1) Turn ignition key to OFF position.
(2) Remove air cleaner.
(3) Verify that lever on throttle body is at curb idle
position (Fig. 224). Then verify that the transmission
throttle lever (Fig. 225) is also at idle (fully forward)
position.
(4) Slide cable off attachment stud on throttle body
lever.
(5) Compare position of cable end to attachment
stud on throttle body lever:
²Cable end and attachment stud should be
aligned (or centered on one another) to within 1 mm
(0.039 in.) in either direction (Fig. 226).
²If cable end and attachment stud are misaligned
(off center), cable will have to be adjusted as
described in Throttle Valve Cable Adjustment proce-
dure.

(20) Reaching through a case opening in the valve
body area with a long blunted tool, remove the trans-
mission front cover from the transmission case.
(21) Remove the bolts holding the oil pump into
the transmission case (Fig. 22).
(22) Remove the oil pump. Hold inward on the
input shaft to prevent pulling the input clutch
assembly with the oil pump (Fig. 22).
NOTE: If the input shaft is not held during oil pump
removal, the input clutch assembly will attempt to
move forward with the oil pump and the numbers 2,
3, or 4 bearings inside the input clutch assembly
may become dislodged.
(23) Remove the number 1 bearing from the input
clutch assembly (Fig. 23).
(24) Remove the input clutch assembly from the
transmission case (Fig. 23).
(25) Remove the number 5 bearing and selective
thrust plate from the input clutch assembly (Fig. 23),
or the 4C clutch retainer/bulkhead.
(26) Remove the 4C clutch retainer/bulkhead
tapered snap-ring from the transmission case (Fig.
24).
(27) Remove the 4C clutch retainer/bulkhead from

(31) Install the output shaft selective thrust plate
onto the reaction annulus with the oil grooves facing
the annulus gear and the tabs and notches aligned as
shown in (Fig. 42).
(32) Install the number 6 bearing against the out-
put shaft selective thrust plate with the flat side
against the thrust plate (Fig. 41) and the raised tabs
on the inner race facing the front of the transmis-
sion.
(33) Install the reaction annulus into the reaction
planetary gear set (Fig. 41).
(34) Install the 4C retainer/bulkhead into the
transmission case. Make sure that the oil feed holes
are pointing toward the valve body area. Rotate the
reaction annulus during the installation of the 4C
retainer/bulkhead to ease installation.
(35) Install the 4C retainer/bulkhead tapered
snap-ring into the transmission case (Fig. 43) with
the taper toward the front of the case. Make sure
that the open ends of the snap-ring are located in the
case opening toward the valve body area.
(36) Air check the 2C and 4C clutch operation.
(37) Using Alignment Plate 8261, Adapter 8266-17
from End-Play Tool Set 8266 and Dial Indicator
C-3339, measure and record the output shaft end-
play (Fig. 44). The correct output shaft end-play is
0.22-0.55 mm (0.009-0.021 in.). Adjust as necessary.
Install the chosen output shaft selective thrust plate
and re-measure end-play to verify selection.
(38) Apply a bead of RTV silicone and install the
extension/adapter housing onto the transmission
case.(39) Install and torque the bolts to hold the exten-
sion/adapter housing onto the transmission case. The
correct torque is 54 N´m (40 ft.lbs.).
(40) Install the number 5 bearing and selective
thrust plate onto the 4C retainer/bulkhead (Fig. 45).
Be sure that the outer race of the bearing is against
the thrust plate.
(41) Install the input clutch assembly into the
transmission case (Fig. 45). Make sure that the input
clutch assembly is fully installed by performing a
