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
workbench 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 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 fluid for the automatic transaxle: A540E ATF DEXRON
II
A540H ATF Type T or equivalent
Recommended oil for the transfer: Transaxle oil E50, API GL5, SAE 75W±90 or equivalent
GENERAL CLEANING NOTES:
1. All disassembled parts should be washed clean, with 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 spraying
automatic transaxle 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, and reas-
sembly.
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 at 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.

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 (09351±32010)
2. TEST ONE±WAY CLUTCH
With the torque converter made stand, 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 convert-
er 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.
