11. Set the clutch spring compressor set (A) on the spring retainer (B) of the 1st, 2nd, and 3rd clutches
so that it pushes on the clutch return spring (C).
12. Check the placement of the clutch spring compressor set. If either end of the clutch spring
compressor set is set over an area of the spring
retainer which is unsupported by the return spring,
the retainer may be damaged. 13. Compress the return spring until the snap ring can

1. Inspect the 4th and 5th clutch pistons and the clutch piston check valves (A).
2. If the clutch piston check valve is loose or damaged, replace the clutch piston.
3. Check the spring retainer for wear and damage.
4. Check the oil seal (A) on the spring retainer of the 1st, 2nd, and 3rd clutches for wear, damage, and
peeling.
5. If the oil seal is worn, damaged, or peeling, replace the spring retainer. 6. Inspect the clutch discs, the clutch plates, and the
clutch end-plate for wear, damage, and
discoloration.
7. If the clutch discs are worn or damaged, replace them as a set. If the clutch discs are replaced,
inspect the clearance between the clutch end-plate
andthetopdisc.
8. If any plate is worn, damaged, or discolored, replace the damaged plate with a new plate, and
inspect the other wave-plates for a phase
difference. If the clutch plate is replaced, inspect
the clearance between the clutch end-plate and the
top disc.
9. If the clutch end-plate is worn, damaged, or discolored, inspect the clearance between the
clutch end-plate and the top disc, then replace the
clutch end-plate.

Clutch Wave-plate Phase Difference Inspection
A

E
B
C
F G
H I
1. Place the clutch wave-plate (A) on a surface plate,
and set a dial indicator (B) on the wave-plate.
2. Find the bottom (C) of a phase difference of the wave-plate, zero the dial indicator and make a
reference mark on the bottom of the wave-plate.
3. Rotate the 2nd, 4th, and 5th clutch wave-plate about 60-degrees by holding it by its circumference,
and rotate the 1st and 3rd clutch wave-plate about
72-degrees or 54-degrees apart from the bottom.
The dial indicator should be at a top (D) of a phase
difference. Do not rotate the wave-plate by holding
its surface, always rotate it holding its edges.
4. Read the dial indicator. The dial indicator reads the phase difference (E) of the wave-plate between the
bottom and the top.
5. Rotate the 2nd, 4th, and 5th clutch wave-plate about 60-degrees from the top position, and rotate
the 1st and 3rd clutch wave-plate 54-degrees or
72-degrees apart from the top. The dial indicator
should be at the bottom of a phase difference
(F and G). Zero the dial indicator. 6. Measure the phase difference at the other two tops
(H and I) of the wave-plate by following steps 3
thru 5.
7. If two of the three measurements are within the standard, the wave-plate is OK. If two of the three
measurements are out of the standard, replace the
wave-plate.

11. Release the clutch end-plate to lower the clutch
end-plate, then put the clutch compressor
attachment on the end-plate (A).
12. Press the clutch compressor attachment down with 150 160 N (15 16 kgf, 33 35 lbf) using a force
gauge, and read the dial indicator (B).
13. The dial indicator reads the clearance (C) between the clutch end-plate and top disc (D). Take
measurements in at least three places, and use
average as the actual clearance.

NOTE: Hold the spring compressor set in a vise with
soft jaws. Be careful not to damage the clutch drum.
1. Soak the clutch discs thoroughly in ATF for at least 30 minutes.
2. Install a new O-ring (A) in the 1st, 2nd, and 3rd clutch pistons (B), and install a new O-ring (C) on
the clutch drums (D). 3. Install the clutch piston (A) in the clutch drum (B)
while applying pressure and rotating to ensure
proper seating. Do not pinch the O-ring.

ring can be installed. Check that the spring retainer
(A) is properly installed on the clutch hub (B). If
improperly installed, change the position of the
spring compressor set and the spring retainer.
NOTE: Insert the spring retainer so it can be
adjusted (center of tolerance) to prevent damaging
the spring retainer oil seal.
8. Install the snap ring using snap ring pliers.
9. Remove the clutch spring compressor set.
