(3) Position the converter in its normal operating
position with the drain plug at the lowest point. Re-
move the drain plug and drain the solvent. Rotate the
turbine and stator, and shake the converter while
draining to prevent dirt particles from settling.
(4) Repeat the flushing operation at least once, or
as many times as required until the solvent or kero-
sene drained out is clear.
(5) After flushing, shake and rotate the converter
several times with the drain plug out to remove any
residual solvent and dirt. Flush any remaining sol-
vent from the converter with two quarts of new trans-
mission fluid. This will prevent any adverse effect the
solvent may have on the transmission seals. Reinstall
the drain plug and tighten to 14 foot-pounds torque.
