AUTOMATIC TRANSMISSION
E: INSPECTION
1. FRONT, MIDDLE & REAR PLANETARY
CARRIER ASSY
Inspect the followings:
• 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
brakeage.
2. INPUT CLUTCH
Check for damage of drive plate, driven plate and
snap ring, and replace them as input clutch assem-
bly if damaged.
3. HIGH & LOW REVERSE CLUTCH AS-
SEMBLY
Check the clearance of high & low reverse clutch.
Measure the clearance "L" between snap ring and
retaining plate using thickness gauge. If the mea-
sured value is out of specification, replace them as
high & low reverse clutch assembly.
Standard value:
1.8 — 2.2 mm (0.070 — 0.087 in)
L
4. DIRECT CLUTCH ASSEMBLY
Check the clearance of direct clutch.
Measure the clearance "L" between snap ring and
retaining plate using thickness gauge. If the mea-
sured value is out of specification, replace them as
direct clutch assembly.
AT Main Case
Standard value:
0.6 — 0.8 mm (0.024 — 0.031 in)
5. REVERSE BRAKE
Check the following items:
• Drive plate facing for wear and damage
• Snap ring for wear, return spring for breakage,
and spring retainer for deformation
• Lip seal and D-ring for damage
• Piston operation
F: ADJUSTMENT
1) Using the ST, measure the height "A" from AT
main case mating surface to convex surface of oil
pump cover.
ST 499575400
AT-02010
2) Using the ST, measure the depth "B" from the
convex surface of oil pump cover to thrust bearing
transferring surface.
ST 499575400
3) Calculate the measured value on step 1) and 2),
and then set the calculated value as "C"
Calculation formula: C = A " B
