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 component group. If a component group can not be assembled because parts are being or-
dered, be sure tc keep all parts of that group in a separate container while proceeding with dis-
assembly, inspection, repair and assembly of other component groups.
Recommended fluid for the automatic transaxle is ATF type DEXRON) ll.
GENERAL CLEANING NOTES:
1. All disassembled parts should be washed clean with any fluid passages and holes blown trough wit com-
pressed air.
2. When using compressed air to dry parts, always aim away from yourself to prevent accidentally spraying,
automatic transmission fluid or kerosene in your face.
3. The recommended automatic transaxle fluid or kerosene should be used for cleaning.
PARTS ARRANGEMENT:
1. After cleaning, the parts should be arranged in proper order to allow efficient inspection, repairs, an(
reassembly.
2. When disassembling a valve body, be sure to keep each valve together with the corresponding spring
3. New brakes and clutches that are to be used for replacement must be soaked in transaxle fluid for a least
fifteen 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.

8. REMOVE OIL PAN AND GASKET
(a) Remove the fifteen bolts.
(b) Remove the oil pan by lifting transmission case.
NOTICE: Do not turn the transmission over as this will con-
taminate the valve body with the foreign materials in the
bottom of the oil pan.
(c) Place the transmission on wooden blocks to prevent
damage to the tube bracket.
9. EXAMINE PARTICLES IN PAN
Remove the magnets and use them to collect any steel
chips. Look carefully at the chips and particles in the oil
pan and on the magnets to anticipate what type of wear
you will find in the transmission:
Steel (magnetic) ...bearing, gear and plate wear
Brass (non±magnetic) ...bushing wear (b) Remove the governor cover.
(c) Remove the governor body and thrust washer.
(d) Remove the plate washer and governor body
adaptor. 7. (A 140 L)
REMOVE GOVERNOR BODY
(a) Remove the two bolts and cover bracket.(c) Remove the speed sensor.

22. REMOVE OIL PUMP AND DIRECT CLUTCH
While holding the input shaft, grasp the pump stator
shaft and pull the oil pump and direct clutch together
out the transmission case.
NOTICE: Push the 2nd coast brake band into the case, be-
ing careful not to catch it on the direct clutch
drum. 21. REMOVE OIL PUMP AND DIRECT CLUTCH
NOTICE: Before removing the oil pump, remove the
second coast brake piston.
(a) Remove the seven bolts. .
23. REMOVE DIRECT CLUTCH FROM OIL PUMP
24. BE CAREFUL WHEN REMOVING RACE BEHIND OIL
PUMP(b) Using SST, pull out the oil pump from the trans-
mission case.
SST 09350±32014 (09351±32061) (b) Remove the cover.
(c) Remove the piston and outer return spring.
(d) Remove the O±ring from the cover.

50. REMOVE OVERDRIVE UNIT WITH ALL PARTS
(a) Tap on the overdrive case circumference with¿plas-
tic hammer to remove the unit from the transmis.
sion case.
(b) Remove the overdrive planetary gear and counter
gear if they remained in the transmission.
HINT: The overdrive unit is heavy, so be careful not tc
drop it. 48. TURN TRANSMISSION CASE AROUND
49. REMOVE ELEVEN BOLTS HOLDING OVERDRIVE
UNIT TO TRANSMISSION CASE
(c) Remove the overdrive brake drum from the
transmission case. 46. REMOVE SNAP RING HOLDING FLANGE TO CASE
47. REMOVE FLANGES. PLATES AND DISCS

53. REMOVE FIRST AND REVERSE BRAKE PISTON
(a) Apply compressed air into the passage of the case to
remove the piston.
HINT: Hold the piston so it is not slanted and blow with
the gun 'slightly away from the oil hole. 52. REMOVE PISTON RETURN SPRING
(a) Place SST, and compress the return springs evenly by
tightening the bolt gradually.
SST 09350±32014 (09351±32040)
(b) Using snap ring pliers, remove the snap ring.
(c) Remove SST.
(d) Remove the return spring from the case. 51. REMOVE± OVERDRIVE CLUTCH APPLY GASKET AND

Torque Converter
INSPECTION OF TORQUE CONVERTER
1. INSERT SST IN END OF TORQUE CONVERTER
(a) Insert a turning tool into the inner race of the one±way
clutch.
SST 09350±32014 f09351±320101
2. TEST ONE±WAY CLUTCH
With the torque converter standing on its side, the
clutch should lock when turned counterclockwise, and
rotate freely and smoothly clockwise.
If necessary, clean the converter and retest the clutch.
Replace the converter if the clutch still fails the test.
CLEAN TORQUE CONVERTER
If the transmission is contaminated, the torque converter and
transmission cooler should be thoroughly flushed
with ATF.(b) Insert the stopper so that it fits in the notch of the
converter hub and outer race of the one±way
clutch.
