CLEANING AND INSPECTION (Continued)
Be sure a replacement sprag is installed so the
sprag locking lug will face the park gear (Fig. 169).
Also be sure the spring is correctly positioned as
shown (Fig. 169). The sprag may not retract if the
spring is improperly installed.

• converter clutch solenoid
The remaining valve body components are serviced
only as part of a complete valve body assembly.
Clean the valve body components in a parts clean-
ing solution only. Do not use gasoline, kerosene, or
any type of caustic solution. Dry the parts with com-
pressed air. Make sure all passages are clean and
free from obstructions.
NOTE: Do not use rags or shop towels to wipe off
valve body components. Lint from these materials
will adhere to the valve body components. Lint will
interfere with valve operation and may clog filters
and fluid passages.
Inspect the throttle and manual valve levers and
shafts. Do not attempt to straighten a bent shaft or
correct a loose lever. Replace these components if
worn, bent, loose or damaged in any way.
Inspect all of the valve body mating surfaces for
scratches, nicks, burrs, or distortion. Use a straight-
edge to check surface flatness. Minor scratches may
be removed with crocus cloth using only very light
pressure.
Minor distortion of a valve body mating surface
may be corrected by smoothing the surface with cro-
cus cloth. The cloth should be in sheet form and be
positioned on a surface plate, sheet of plate glass, or
equally flat surface. However, if distortion is severe
