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.

4) Remove output shaft speed sensor (1) and input shaft speed
sensor (2).
5) Remove transmission range sensor (3).
6) Remove dropping resistor (4).
7) Remove breather hose (5).
8) Remove A/T fluid level gauge (1) and filler tube (2).

temperature sensor (2).
NOTE:
 For removal of oil pan, do not turn transmission over
as this will contaminate valve body with foreign materi-
als in the bottom of oil pan.
 When removing oil pan, tap around it lightly with a
plastic hammer. Do not force it off by using a screw-
driver or the like.

12) Disconnect couplers from solenoid valves, and transmission
temperature sensor.
Remove transmission temperature sensor.
13) Remove valve body assembly (1).
14) Remove solenoid harness assembly.
15) Remove accumulator pistons and springs.
To remove C0 (1), C2 (2) and B1 (3) accumulator pistons
and springs, position a rag on pistons to catch each piston.
To remove pistons, force low-pressure compressed air (1 kg/
cm
2, 15 psi, 100 kPa, max) into hole (4) as shown in figure,
and pop each piston into the rag.
To remove B0 and C1 accumulator pistons and springs,
remove each snap ring and accumulator spacer, then
remove spring and piston.
16) Remove torque converter housing (1).
a) Remove housing bolts.
b) Remove housing while tapping around it lightly with a plas-
tic hammer. CAUTION:
Be careful not to let manual valve fall off when removing
valve body assembly.
NOTE:
There are three kinds of bolts (bolts A, B and C) fixing
valve body assembly.
2. Bolt A
3. Bolt B
4. Bolt C
NOTE:
Do not push accumulator pistons with fingers or any-
thing before removing them. Pushing them may cause
compressed fluid in accumulator to spew out of hole and
get to your face and clothes.
NOTE:
Never reuse bolts A shown in figure.

INSPECTION
Clutch and Brake Discs
Dry and inspect them for pitting, burn flaking, wear, glazing,
cracking, charring and chips or metal particles imbedded in lining.
If discs show any of the above conditions, replacement is
required.
Clutch and Brake Plates and Flanges
Dry plates and check for discoloration. If plate surface is smooth
and even color smear is indicated, the plate should be reused. If
severe heat spot discoloration or surface scuffing is indicated, the
plate must be replaced.
1st & 2nd Brake Piston Return Spring Subassembly
Measure height of 1st & 2nd brake piston return spring.
Height of 1st & 2nd brake piston return spring
20.81 mm (0.819 in.)
Evidence of extreme heat or burning in the area of clutch may
have caused springs to take a heat set and would require their
replacement.NOTE:
 If disc lining is exfoliated or discolored, replace all
discs.
 Before assembling new discs, soak them in A/T fluid
for at least two hours.
NOTE:
 Do not apply excessive force when measuring spring
height.
 Perform measurement at several points.
