ing compressed air (392-785 kPa, 4-8 kgf/cm
2, 57-114
psi).
SST 09240-00020
Piston stroke:
1.5-3.0 mm (0.059-0.118 in.)
If the values are non-standard, inspect the brake band.
32. REMOVE SECOND COAST BRAKE COVER, PISTON
ASSEMBLY AND SPRING
(a) Using SST, remove the snap ring.
SST 09350-30020 (09350-07060)
(b) Applying compressed air to the oil hole, remove the se-
cond coast brake cover, piston assembly and spring.

35. REMOVE FRONT PLANETARY GEAR UNIT
(a) Remove the front planetary ring gear from the case.
(b) Remove the bearing and race from the front planetary
ring gear.
(c) Remove the race from the front planetary gear.
(d) With wooden blocks under the output shaft, stand the
transmission on the output shaft.

36. REMOVE FRONT PLANETARY GEAR
(a) Using SST, remove the snap ring.
SST 09350-30029 (09350-07070)
HINT: Pushing the output shaft towards the front makes
it easier to remove.
37. REMOVE PLANETARY SUN GEAR WITH NO.1 ONE-
WAY CLUTCH
(a) Remove the planetary sun gear with No.1 one-way clutch
from the case.
(b) Remove the thrust washer.
38. CHECK PACK CLEARANCE OF SECOND BRAKE
Using a feeler gauge, measure the clearance between
the snap ring and flange.
Clearance:
0.62-1.98 mm (0.0244-0.0780 in.)
If the values are non-standard, inspect the discs.
39. REMOVE FLANGE, PLATES AND DISCS OF SECOND
BRAKE
(a) Remove the snap ring.
(b) Remove the flange, plates and discs.

40. CHECK PACK CLEARANCE OF FIRST AND REVERSE
BRAKE
Using a feeler gauge, measure the clearance between
the plate and second brake drum.
Clearance:
0.60-1.12 mm (0.0236-0.0441 in.)
If the values are non-standard, inspect the discs.
41. REMOVE SECOND BRAKE PISTON SLEEVE
42. REMOVE REAR PLANETARY GEAR WITH SECOND
BRAKE DRUM, FIRST AND REVERSE BRAKE PACK
AND OUTPUT SHAFT
(a) Using SST and screwdriver, remove the snap ring.
SST 09350-30020 (09350-07060)
(b) Remove the rear planetary gear, second brake drum, first
and reverse brake pack and output shaft as an assembly.
(c) Remove the assembled thrust bearing and race from the
case.

COMPONENT PARTS
General Notes
The instructions here are organized so that you work on only one component group at a time.
This will help avoid confusion from similar-looking parts of different subassemblies being on your work-
bench at the same time.
The component groups are inspected and repaired from the converter housing side.
As much as possible, complete the inspection, repair and assembly before proceeding to the next compo-
nent group. If a component group cannot be assembled because parts are being ordered, be sure to keep
all parts of that group in a separate container while proceeding with disassembly, inspection, repair and
assembly of other component groups.
Recommended ATF:
DEXRON® II
GENERAL CLEANING NOTES:
1. All disassembled parts should be washed clean and any fluid passages and holes blown through with
compressed air.
2. When using compressed air to dry parts, always aim away from yourself to prevent accidentally spray-
ing automatic transmission fluid or kerosene in your face.
3. The recommended automatic transmission fluid or kerosene should be used for cleaning.
PARTS ARRANGEMENT:
1. After cleaning, the parts should be arranged in the correct order to allow efficient inspection, repairs,
and reassembly.
2. When disassembling a valve body, be sure to keep each valve together with the corresponding spring.
3. New discs for the brakes and clutches that are to be used for replacement must be soaked in transmis-
sion fluid for at least 15 minutes before assembly.
GENERAL ASSEMBLY:
1. All oil seal rings, clutch discs, clutch plates, rotating parts, and sliding surfaces should be coated with
transmission fluid prior to reassembly.
2. All gaskets and rubber O-rings should be replaced.
3. Make sure that the ends of a snap ring are not aligned with one of the cutouts and are installed in the
groove correctly.
4. If a worn bushing is to be replaced, the subassembly containing that bushing must be replaced.
5. Check thrust bearings and races for wear or damage. Replace if necessary.
6. Use petroleum jelly to keep parts in place.
