6. Remove the console cover.
7. Remove the shifter boot.
8. Remove the shifter mounting bolt
s and remove the shifter assembly.
9. Installation is the reverse of the removal procedure. Adjust the linkage as
detailed earlier.
BACK-UP LIGHT SWITCH
REMOVAL & INSTALLATION 1. Disconnect the negative battery terminal from the battery.
2. At the left-rear of the transmission, the back-up light switch is threaded
into the transmission case. The speed sensor is held in with a separate
bracket. Disconnect the electrical co nnector from the back-up light
switch.
3. Remove the back-up light swit ch from the transmission.
4. To install, reverse the remova l procedures. Coat the threads with
Teflon® tape. Please refer to the to rque chart for specifications. Place
the gear shift lever in the revers e position and check that the back-up
lights work.
EXTENSION HOUSING SEAL
REMOVAL & INSTALLATION
This seal controls transmission oil leakage around the driveshaft. Continued
failure of this seal usually indicates a worn output shaft bushing. If so, there will
be signs of the same wear on the driveshaft where it contacts the seal and
bushing. The seal is available and is fairly simple to install, with the proper tool.
1. Raise and safely support the rear of the vehicle to minimize transmission
oil loss when the driveshaft is removed.
2. Unbolt the driveshaft fr om the differential and center support bearing, if
equipped. Wrap tape around the bearing cu ps to keep them in place on
the universal joint and slide the sh aft out of the transmission.
3. Use an small pry tool to carefully pry out the old seal. Be careful not to
insert the tool too far into the hous ing or the bushing will be damaged.

3. Disconnect all wiring from the star
ter solenoid. Replace each nut as the
connector is removed (as thread sizes differ from connector to
connector). Note or tag the wiring positions for installation.
4. Remove the bracket from the st arter and the two mounting bolts. On
engines with a solenoid heat shield, remove the front bracket upper bolt
and detach the bracket fr om the starter.
5. Remove the front bracket bolt or nut. Lower the starter front end first, and
then remove the unit from the car.
To install: 6. Position the starter into place and se cure it with the front bracket bolt and
nut. Torque the two mounting bolts to 25-35 ft. lbs.
CAUTION - If shims were removed, they must be replaced to ensure proper
pinion-to-flywheel engagement.
7. On engines with a solenoid heat shield, attach the bracket to the starter.
Install the bracket to the starter and the two mounting bolts. Install the
front bracket upper bolt.
8. Connect all wiring to the starte r solenoid and tighten the nuts.
9. Lower the vehicle.
10. Connect the negative battery cable.
SOLENOID REPLACEMENT 1. Remove the screw and washer from the motor connector strap terminal.
2. Remove the two solenoid retaining screws.
3. Twist the solenoid housing clockwis e to remove the flange key from the
keyway in the housing. Then remove the housing.
4. To re-install the unit, place the re turn spring on the plunger and place the
solenoid body on the driv e housing. Turn counterclockwise to engage the
flange key. Place the two retaining screws in position and install the
screw and washer which secures the strap terminal. Install the unit on
the starter.
