(8) Install thrust bearing in overdrive unit sliding
hub. Use petroleum jelly to hold bearing in position.
CAUTION:
Be sure the shoulder on the inside
diameter of the bearing is facing forward.
(9) Verify that splines in overdrive planetary gear
and overrunning clutch hub are aligned with Align-
ment Tool 6227-2. Overdrive unit cannot be
installed if splines are not aligned. If splines
have rotated out of alignment, unit may have to
be disassembled to realign splines.
(10) Carefully slide Alignment Tool 6227-2 out of
overdrive planetary gear and overrunning clutch
splines.
(11) Raise overdrive unit and carefully slide it
straight onto intermediate shaft. Insert park rod into
park lock reaction plug at same time. Avoid tilting
overdrive during installation as this could
cause planetary gear and overrunning clutch
splines to rotate out of alignment. If this
occurs, it will be necessary to remove and dis-
assemble overdrive unit to realign splines.
(12) Align slip-fit governor tubes and work over-
drive unit forward on intermediate shaft until seated
against transmission case.
(13) Install bolts attaching overdrive unit to trans-
mission unit. Tighten bolts in diagonal pattern to 34
N·m (25 ft-lbs).
(14) Install crossmember.
(15) Install speed sensor and speedometer adapter.
Be sure to index adapter.
(16) Connect speed sensor and overdrive wires.
(17) Align and install propeller shaft.
(18) If valve body was also removed, adjust bands,
install valve body and install transmission oil pan
and gasket.
TRANSMISSION/OVERDRIVE
The overdrive unit can be removed and serviced
separately. It is not necessary to remove the entire
transmission assembly to perform overdrive unit
repairs.
The entire transmission assembly must be removed
in order to service the torque converter, driveplate,
ring gear and oil pump. Refer to the transmission
removal and installation procedures in this section.
If only the overdrive unit requires service, refer to
the overdrive unit removal and installation proce-
dures.
CAUTION:
The transmission and torque converter
must be removed as an assembly to avoid compo-
nent damage. The converter drive plate, pump
bushing, or oil seal can be damaged if the con-
verter is left attached to the driveplate during
removal. Be sure to remove the transmission and
converter as an assembly.
REMOVAL
(1) Disconnect battery negative cable.
(2) Disconnect and lower or remove necessary
exhaust components.
(3) Remove
engine-to-transmission
struts,
if
equipped (Fig. 55).
(4) Disconnect fluid cooler lines at transmission.
(5) Remove starter motor.
(6) Disconnect and remove crankshaft position sen-
sor. Retain sensor attaching bolts.
CAUTION:
The crankshaft position sensor will be
damaged
if
the
transmission
is
removed
(or
installed) while the sensor is still bolted to the
engine block. To avoid damage, be sure to remove
the sensor before removing the transmission.
(7) Remove torque converter access cover.
(8) If transmission is being removed for overhaul,
remove transmission oil pan, drain fluid and reinstall
pan.
(9) Remove fill tube bracket bolts and pull tube
out of transmission. Retain fill tube O-ring (Fig. 55).
On 4 x 4 models, it will also be necessary to remove
bolt attaching transfer case vent tube to converter
housing (Fig. 56).
(10) Mark torque converter and drive plate for
assembly alignment. Note that bolt holes in crank-
