WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System :
• Service on and around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” in air bag system section before performing service
on or around the air bag system components or wiring. Failure to follow WARNINGS could result in
unintentional activation of the system or could render the system inoperative. Either of these two
conditions may result in severe injury.
 Technical service work must be started at least 90 seconds after the ignition switch is turned to the
“LOCK” position and the negative cable is disconnected from the battery. Otherwise, the system
may be activated by reserve energy in the Sensing and Diagnostic Module (SDM).

7A-2 MANUAL TRANSMISSION
GENERAL DESCRIPTION
CONSTRUCTION AND SERVICING
The transmission provides five forward speeds and one reverse speed by means of three synchronizers and
three shafts-input shaft, countershaft and reverse gear shaft. All forward gears are in constant mesh, and
reverse uses a sliding idler gear arrangement.
The low speed synchronizer is mounted on counter shaft and engaged with counter shaft first gear or second
gear, while the high speed synchronizer is done on input shaft and engaged with input shaft third gear or fourth
gear.
The fifth speed synchronizer on input shaft is engaged with input shaft fifth gear mounted on the input shaft.
The double cone synchronizing mechanism is provided to 2nd gear synchromesh device for high performance
of shifting to 2nd gear.
The countershaft turns the final gear and differential assembly, thereby turning the front drive shafts which are
attached to the front wheels.
4WD model is equipped with transfer assembly on transmission being mated to right side of differential output in
transmission.
For servicing, it is necessary to use genuine sealant or its equivalent on mating surfaces of transmission case
which is made of aluminum. The case fastening bolts must be tightened to specified torque by means of torque
wrench. It is also important that all parts are thoroughly cleaned with cleaning fluid and air dried before reas-
sembling.
Further, care must be taken to adjust preload of counter shaft taper roller bearings. New synchronizer rings are
prohibited from being lapped with respective gear cones by using lapping compound before they are assembled.

7) By using large size screwdrivers (2), pull out drive shaft joint
(1) so as to release snap ring fitting of joint spline at differen-
tial side.Pushing knuckle portion outward, detach drive shaft
at differential side.
8) Remove oil seal (1) and install a new one until it becomes
flush with case surface by using special tool and hammer.
Special tool
(A) : 09913-75510 (2WD and LH of 4WD)
(A) : 09951-46010 (RH of 4WD)
9) Apply grease to oil seal lip and at the same time check drive
shaft where oil seal contacts and make sure of its smooth-
ness.
“A” : Grease 99000-25010
10) Insert drive shaft joint to differential gear.
11) Connect ball stud with knuckle and fasten with bolt to specifi-
cation referring to Section 3D.
12) Connect tie-rod end with knuckle and fasten new nut to spec-
ified torque referring to Section 3D.
13) Install stabilizer mount brackets, fasten bolts to specified
torque referring to Section 3D.
14) Fill transmission oil as specified and make sure that oil has
been sealed with oil seal.
NOTE:
When installing oil seal, face its spring side inward.
CAUTION:
 Be careful not to scratch oil seal lip with drive shaft
joint while inserting.
 Make sure to insert drive shaft joint fully and seat its
snap ring as it was.
 Do not hit joint boot with hammer or the like. Nothing
but hands is allowed to use when inserting joint.
