1 General information
All vehicles covered in this manual come
equipped with either a four or five-speed
manual transmission or an automatic trans-
mission. All information on the manual trans-
mission is included in this Part of Chapter 7.
Information on the automatic transmission
can be found in Part B of this Chapter.
Both four and five-speed manual trans-
missions are used in these models. On five-
speed transmissions, the 5th gear is an over-
drive.
Due to the complexity, unavailability of
replacement parts and the special tools nec-
essary. internal repair by the home mechanic
is not recommended. The information in this
Chapter is limited to general information and
removal and installation of the transmission.
Depending on the expense involved in
having a faulty transmission overhauled, it

may be a good idea to replace the unit with
either a new or rebuilt one. Your local dealer
or transmission shop should be able to sup-
ply you with information concerning cost,
availability and exchange policy. Regardless
of how you decide to remedy a transmission
problem, you can still save a lot of money by
removing and installing the unit yourself.
2 Oil seal replacement
Refer to illustrations 2.6, 2.11, 21.13a
and 2.13b
1 Oil leaks frequently occur due to wear of
the extension housing oil seal and/or the
speedometer drive gear oil seal and O-ring.
Replacement of these seals is relatively easy,
since the repairs can usually be performed
without removing the transmission or transfer
case (4WD models) from the vehicle.
2 The extension housing oil seal is located
at the extreme rear of the transmission or
transfer case, where the driveshaft is
attached. If leakage at the seal is suspected,
raise the vehicle and support it securely on
jackstands. If the seal is leaking, transmission
lubricant will be built up on the front of the
driveshaft and may be dripping from the rear
of the transmission or transfer case.
3 Refer to Chapter 8 and remove the
driveshaft.
4 Using a soft-faced hammer, carefully
tap the dust shield (if equipped) to the rear
and remove it from the transmission. Be
careful not to distort it.
5 Using a screwdriver or pry bar, carefully
pry the oil seal out of the rear of the transmis-
sion or transfer case. Do not damage the
splines on the transmission output shaft.
6 If the oil seal cannot be removed with a
screwdriver or pry bar, a special oil seal

2.11 Before loosening the retaining bolt, mark the relationship
between the speedometer adapter housing and the transmission
or transfer case with white paint - the adapter is offset and must
be installed in the same relationship (retaining bolt shown
removed for clarity)
