TORQUE CONVERTER
INSPECTION AND REPAIR
Insert special tool in end of torque converter
Insert a turning tool into the inner race of the one–way
clutch.
One–way clutch testing tool : 5–8840–2168–0 (J–35467)
Insert the stopper so that it fits in the notch of the converter
hub and outer race of the one–way clutch.
Test one–way clutch
The clutch should lock when turned counterclockwise, and
rotate freely and smoothly clockwise. Less than 25kg·cm
(22 Ib·in) of torque should be required to rotate the clutch
clockwise. If necessary, clean the converter and retest the
clutch. Replace the converter if the clutch still fails the test.

REASSEMBLY OF MAJOR COMPONENTS
Disassembly, inspection and reassembly of each
component group have been indicated in the preceding
chapter. Before reassembly, make sure, again, that all
component groups are assembled correctly.
If something wrong is found in a certain component group
during assembly, inspect and repair this group immediately.
GENERAL ASSEMBLY NOTES:
1. The automatic transmission is composed of highly
precision–finished parts, necessitating careful inspection
before assembly because even a small nick could cause
fluid leakage or affect performance.
2. Before assembling new clutch discs and brake bands, soak
them in automatic transmission fluid for at least thirty
minutes.
3. Apply automatic transmission fluid on the sliding or rotating
surfaces of parts before assembly.
4. Use petroleum jelly to keep small parts in their places.
5. Do not use adhesive cements on gaskets and similar parts.
6. When assembling the transmission, be sure to use new
gaskets and O–rings.
7. Dry all parts with compressed air - never use shop rags.
8. Be sure to install the thrust bearings and races in the
correct direction and position.
