DISMOUNTING
1) Take down transmission with engine. For its procedure, refer
to Section 6A1.
2) For 4WD vehicle, remove transfer referring to Section 7D
For 2WD vehicle, remove engine rear mounting No.1
bracket and engine rear mounting No.2 bracket with stiff-
ener.
3) Remove torque converter housing lower plate (1).
4) Remove drive plate bolts.
To lock drive plate (1), engage a flat head rod or the like (2)
with drive plate gear.
5) Remove starting motor.
6) Remove bolts and nut fastening engine and transmission,
then detach transmission from engine.
NOTE:
When detaching transmission from engine, move it in
parallel with crankshaft and use care so as not to apply
excessive force to drive plate and torque converter.
WARNING:
Be sure to keep transmission with torque converter hori-
zontal or facing up throughout the work. Should it be
tilted with torque converter down, converter may fall off
and cause personal injury.

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.

discs, brake plates and cushion plate.
25) Remove oil guide plate (1) parking lock pawl cover (2), shaft,
torsional spring (3) and parking lock pawl (4).
26) Remove parking lock pawl sleeve (5).

AUTOMATIC TRANSMISSION (4 A/T) 7B-83
27) Remove counter driven gear assembly (1) and thrust needle
roller bearing (2).
28) Remove control shift lever (1), nuts (2), washer (3) from
manual shift shaft (4).
29) Remove detent spring (1).
30) Remove manual shift shaft (1) with parking lock rod (2), and
washer (3) from transmission case.

DISASSEMBLY/ASSEMBLY OF SUBASSEMBLY
OIL PUMP
CAUTION:
 Keep component parts in group for each subassembly and avoid mixing them up.
 Clean all parts with cleaning solvent thoroughly and air dry them.
 Use kerosene or automatic transmission fluid as cleaning solvent.
 Do not use wiping cloths or rags to clean or dry parts.
 All oil passages should be blown out and checked to make sure that they are not obstructed.
 Keep face and eyes away from solvent spray while air blowing parts.
 Check mating surface for irregularities and remove them, if any, and clean it again.
 Soak new clutch discs and brake discs in transmission fluid for at least 2 hours before assembly.
 Replace all gaskets and O-rings with new ones.
 Apply automatic transmission fluid to all O-rings.
 When installing seal ring, be careful so that it is not expanded excessively, extruded or caught.
 Replace oil seals that are removed and apply grease to their lips.
 Before installing, be sure to apply automatic transmission fluid to sliding, rolling and thrusting sur-
face of all component part. Also after installation, make sure to check each part for proper opera-
tion.
 Always use torque wrench when tightening bolts.
1. Oil seal
: Apply grease 99000-25030 to oil seal lip.7. Clutch drum thrust washer
2. D-ring
: Apply grease 99000-25030 to all over surface. 8. Clutch drum oil seal ring
: Apply grease 99000-25030 to all over surface.
3. Oil pump body Apply automatic transmission fluid.
4. Oil pump drive gear Tightening torque
5. Oil pump driven gear Do not reuse.
6. Stator shaft assembly

AUTOMATIC TRANSMISSION (4 A/T) 7B-89
DISASSEMBLY
1) Remove D-ring from pump body.
2) Remove 2 oil seal rings and clutch drum thrust washer.
3) Remove 11 bolts.
4) Separate pump body from stator shaft assembly.
5) Remove oil seal from pump body.
INSPECTION
1) Inspect pump body oil seal.
Check for wear, damage or cracks.
Replace oil seal if necessary and apply grease to its lip por-
tion slightly when it is installed.
2) Check body clearance of driven gear.
Push driven gear to one side of body. Using a feeler gauge,
measure clearance between driven gear and body.
If clearance exceeds its standard value, replace oil pump
assembly.
Clearance between oil pump driven gear and oil pump
body
Standard : 0.08 – 0.15 mm (0.0027 – 0.0059 in.)
Limit : 0.30 mm (0.018 in.)
3) Check tip clearance of both drive and driven gears.
Measure radial clearance between gear tooth and crescent.
If clearance exceeds its standard value, replace oil pump
assembly.
.Radial clearance between oil pump gear tooth and oil
pump crescent
Standard : 0.13 – 0.20 mm (0.0051 – 0.0079 in.)
Limit : 0.30 mm (0.018 in.)
4) Check side clearance of both gears.
Using a straightedge (1) and a feeler gauge (2), measure
side clearance between gear and pump body.
If clearance exceeds its standard value, replace oil pump
assembly.
Side clearance between gear and oil pump body
Standard : 0.02 – 0.04 mm (0.0008 – 0.0015 in.)
1. Oil pump drive gear
2. Driven gear
3. Body
1. Pump body crescent portion
