immediately note cooler flow. Approximately one
quart of fluid should flow into test container in 20

INSPECTION
(1) Insert Rotating Tool 7547 into converter hub
and seat tool in one–way clutch (Fig. 43).
(2) Insert Stopper Tool 7548 in one converter hub
notch and into outer race of rotating tool.
(3) Turn rotating tool clockwise. Converter clutch

(22 in. lbs.) of torque should be required to rotate
clutch in clockwise direction.
(4) Turn rotating tool in counterclockwise direc-
tion. Converter clutch should lock.
(5) Replace converter if clutch binds or will not
lock.
SERVICE PROCEDURES
CHECKING FLUID LEVEL
(1) Be sure transmission fluid is at normal operat-
ing temperature. Normal operating temperature is
reached after approximately 15 miles (25 km) of
operation.
(2) Position vehicle on level surface. This is impor-
tant for an accurate fluid level check.
(3) Shift transmission through all gear ranges and
back to Park.
(4) Apply parking brakes.
(5) Verify that transmission is in Park.
(6) Wipe off dipstick handle to prevent dirt from
entering fill tube. Then remove dipstick and check
fluid level and condition.
(7) Correct fluid level is to FULL mark on dip-
stick when fluid is at normal operating temper-
ature (Fig. 44).
(8) If fluid level is low, top off level with Mopar
Dexron IIE/Mercon. Mopar Dexron II can be used but
only if Mercon is not available. Do not overfill
transmission. Add only enough fluid to bring
level to Full mark.
(9) If too much fluid was added, excess amount can
be removed with suction gun and appropriate diame-
