FLUID LEVEL AT ROOM TEMPERATURE
INSPECTION
The fluid level check at room temperature performed after repair
or fluid change before test driving is just preparation for level
check of normal operation temperature. The checking procedure
itself is the same as that described previously. If the fluid level is
between FULL COLD and LOW COLD, proceed to test drive. And
when the fluid temperature has reached the normal operating
temperature, check fluid again and adjust it as necessary.
FLUID CHANGE
1) Lift up vehicle.
2) When engine has cooled down, remove drain plug (1) from
oil pan and drain A/T fluid.
3) Install drain plug.
Tightening torque
A/T fluid drain plug (a) : 23 N·m (2.3 kg-m, 16.5 lb-ft)

INSTALLATION
1) Install shift solenoid valves.
Tightening torque
Solenoid valve bolts (a) : 8 N·m (0.8 kg-m, 6.0 lb-ft)
2) Connect shift solenoid couplers.
3) Install oil strainer (2) and transmission temperature sensor
(1).
Tightening torque
Transmission temperature sensor bolt
(b) : 10 N·m (1.0 kg-m, 7.5 lb-ft)
4) Connect transmission temperature sensor coupler (3).
5) Clean mating surface of A/T oil pan (1) and A/T case.
6) Install new gasket (2) to A/T oil pan.
7) Install A/T oil pan.
Tightening torque
A/T oil pan bolts (a) : 7.5 N·m (0.75 kg-m, 5.5 lb-ft)
8) Install A/T fluid drain bolt.
Tightening torque
A/T fluid drain bolt (b) : 23 N·m (2.3 kg-m, 16.5 lb-ft)
9) Refill A/T fluid referring to “FLUID CHANGE” in this section.
10) Verify that there is no A/T fluid leakage.
NOTE:
Do not forget to install O-ring (4) to oil strainer first.

DIFFERENTIAL SIDE OIL SEAL
REPLACEMENT
1) Lift up vehicle and drain transmission oil.
2) Remove drive shaft joints from differential gear of transmis-
sion.
Refer to Section 4 for procedure to disconnect drive shaft
joints.
For differential side oil seal removal, it is not necessary to
remove drive shafts from steering knuckle.
For 4WD vehicle, remove transfer referring to Section 7D.
3) Remove differential side oil seal (1) by using flat end rod or
like.
4) Install new differential side oil seal by using special tool.
Special tool
(A) : 09940-53111
(B) : 09913-75510
5) Install drive shaft referring to Section 4.
6) Refill A/T fluid referring to “FLUID CHANGE” in this section. NOTE:
For oil seal installation, press-fit oil seal so that transmis-
sion case end face is flush with oil seal end face.

3) Measure backlash by using dial gauge.
Drive bevel gear backlash
: 0.10 – 0.20 mm (0.0039 – 0.0078 in.)
Special tool
(A) : 09900-20606
(B) : 09900-20701
4) Check gear tooth contact as follows.
a) After cleaning tooth surface of drive bevel gears, paint them
with gear marking compound evenly by using brush or
sponge etc.
b) Turn gear to bring its painted part in mesh with bevel pinion
and turn it back and forth by hand to repeat their contact.
c) Bring painted part up and check contact pattern, referring to
the following chart. If contact pattern is not normal, readjust
or replace as necessary according to instruction in chart.
5) After completing of gear tooth contact check caulk bevel pin-
ion nut with caulking tool and hammer. NOTE:
 Be sure to apply measuring tip of dial gauge at right
angles to convex side (drive side) of tooth.
 If backlash is out of specification, change division of
shims so that backlash is within specification.
CAUTION:
When applying red lead paste to teeth, be sure to paint
tooth surfaces uniformly. The paste must not be too dry
or too fluid.
NOTE:
Be careful not to turn bevel gear more than one full revo-
lution, for it will hinder accurate check.
