14. CHECK OPERATION OF ONE±WAY CLUTCH
(a) While turning the overdrive gear clockwise, install the
overdrive direct clutch into the one±way clutch.
(b) Hold the overdrive direct clutch and turn the intermedi-
ate shaft. The shaft should turn freely clockwise and
should lock counterclockwise.
(e) Remove the overdrive direct clutch. 11. ASSEMBLE OVERDRIVE ONE±WAY CLUTCH
(a) Install the one±way clutch into the outer race.
(b)Install a retainer on both sides of the one±way 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.

fied preload is reached.
If the maximum torque is exceeded while retightening
the nut, replace the bearing spacer and repeat the pre-
load procedure.
Do not back off the nut to reduce the preload.
