OPERATION
The converter impeller (Fig. 235) (driving member),
which is integral to the converter housing and bolted
to the engine drive plate, rotates at engine speed.
The converter turbine (driven member), which reacts
from fluid pressure generated by the impeller, rotates
and turns the transmission input shaft.
TURBINE
As the fluid that was put into motion by the impel-
ler blades strikes the blades of the turbine, some of
the energy and rotational force is transferred into the
turbine and the input shaft. This causes both of them
(turbine and input shaft) to rotate in a clockwise
direction following the impeller. As the fluid is leav-
ing the trailing edges of the turbine's blades it con-
tinues in a ªhinderingº direction back toward the
impeller. If the fluid is not redirected before it strikes
the impeller, it will strike the impeller in such a
direction that it would tend to slow it down.

(12) Remove shift/shuttle valves and springs as
shown in (Fig. 320).
CLEANING
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.
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 bepositioned on a surface plate, sheet of plate glass, or
equally flat surface. However, if distortion is severe
or any surfaces are heavily scored, the valve body
will have to be replaced.
CAUTION: Many of the valve body valves and plugs
are made of coated aluminum. Aluminum compo-
nents can be identified by the dark color of the spe-
cial coating applied to the surface (or by testing
with a magnet). DO NOT polish or sand aluminum
valves or plugs with any type of material, or under
any circumstances. This practice might damage the
special coating and cause the valves and plugs to
stick and bind.
Aluminum valves and plugs should not be sanded
or polished under any circumstances. However, minor
burrs or scratches on steel valves and plugs can be
removed with crocus cloth but do not round off the
