4) Install the dish plate.
NOTE:
When installing, make sure that the identification
mark is facing the front side of transmission.
5) Install the drive plate and driven plate.
6) Install the leaf spring.
7) Install the retaining plate.
8) Install the snap ring of the reverse brake.
9) Perform the clearance check of reverse brake.
(1) Measure the clearance between retainer
plate and snap ring using thickness gauge.
Specification:
0.7 — 1.1 mm (0.028 — 0.043 in)
(2) If it is out of specification, select a suitable
retainer plate from the following table and as-
semble it.
10) Install the direct clutch assembly.

E: INSPECTION
1. FRONT, MIDDLE & REAR PLANETARY
CARRIER ASSEMBLY
Check the following items.
•Visually inspect the tooth surface of planetary
gear, and replace with new one if damaged, broken
or excessively worn.
•Inspect the planetary carrier body for damage or
breakage.
2. INPUT CLUTCH
•Check the clearance of the input clutch. Measure
the clearance “L” between snap ring and retaining
plate using a thickness gauge. If it is out of specifi-
cation, replace the entire direct clutch assembly.
•Check for damage on the drive plate, driven plate
and snap ring, and replace the entire input clutch
assembly if damaged.
Specification:
0.7 — 1.1 mm (0.028 — 0.043 in)
3. HIGH & LOW REVERSE CLUTCH AS-
SEMBLY
•Check the clearance of the high & low reverse
clutch.
Measure the clearance “L” between snap ring and
retaining plate using a thickness gauge. If it is out of
specification, replace the entire high & low reverse
clutch assembly.
•Check for damage on the drive plate, driven plate
and snap ring, and replace the entire high & low re-
verse clutch assembly if damaged.
Specification:
1.8 — 2.2 mm (0.070 — 0.087 in)
4. DIRECT CLUTCH ASSEMBLY
•Check the clearance of direct clutch.
Measure the clearance “L” between snap ring and
retaining plate using a thickness gauge. If it is out of
specification, replace them as direct clutch assem-
bly.
•Check for damage on the drive plate, driven plate
and snap ring, and replace the entire direct clutch
assembly if damaged.
Specification:
0.6 — 1.0 mm (0.024 — 0.039 in)
5. REVERSE BRAKE
Check the following items.
•Drive plate facing for wear or damage
•Snap ring for wear, return spring for breakage,
and spring retainer for deformation
•Lip seal and D-ring for damage
•Piston operation
