5. If fluid in the converter has the appearance of having
been mixed with "aluminum paint" converter is da-
maged internally and must be replaced.
6. Do not change the converter if a failure in some other
part of the transmission has resulted in the converter
containing dark, discolored fluid. The full flow filter,
used in the Hydra-Matic unit since late 1967, is de-
signed to remove all harmful residue from failures,
other than converter and/or pump failures, before
the oil is pumped into the converter.
7. Check the converter internally for damage to its
roller bearings, thrust races and the roller clutch (Fig.
7E- 164):
a. The thrust roller bearings and thrust races can be
checked by viewing them when looking into the
converter neck or feeling through the opening to
make sure they are not cracked, broken or mispo-
sitioned.
b. The function of the stator roller clutch can be
checked by placing a finger into the converter
neck and, with side pressure against splines of the
stator race, turning the stator race. The race
should turn fairly freely in a clockwise direction
and not turn in a counterclockwise direction.
