INLET OPENING
Test the filter by pouring clean ATF fluid through
the inlet opening. Beplace the ATF strainer if it is
clogged or damaged.
NOTE: The ATF str8iner can be reused if it is not
clogged.

Repair
NOTE: This repair is only necessary if one or more of
the valves in a valve body do not slide smoothly in their
bores. You may use this procedure to free the valves in
the valve bodies.
1. Soak a sheet of #600 abrasive paper in ATF for
about 30 minutes.
Carefully tap the valve body so the sticking valve
drops out of its bore.
CAUTION: lt may b€ necessary to use a small
screwdriver to pry the valve free. Be careful not to
scratch the bore whh the screwdriver.
Inspect the valve for any scuff marks. Use the ATF-
soaked #600 paper to polish off any burrs that are
on the valve, then wash the valve in solvent and dry
it with compressed a ir.
Roll up half a sheet of ATF-soaked paper, and insert
it in the valve bore of the sticking valve.
Twist the paper slightly, so that it unrolls and fits the
bore tightly, then polish the bore by twisting the
paper as you push it in and out.
CAUTION: The valve body is aluminum and doesn't
require much polishing to remove any burrs,

Remove the #600 paper and thoroughly wash the
entire valve body in solvent. then dry it with com-
pressed air.
Coat the valve with ATF, then drop ir into its bore.
It should drop to the bonom of the bore under its
own weight. lf not, repeat step 4, then retest.
VALVE BODY
Remove the valve. then thoroughly clean it and the
valve body with solvent. Dry all parts with com-
pressed air. then reassemble using ATF as a lubri
cant.

ATF Pump
Inspection
1. Install the ATF pump gears and ATF pump driven
gear shaft in the main valve body
NOTE:
. Lubricate all parts with ATF during inspection.
. Install the ATF pump driven gear with its grooved
and chamfered side facing up as shown.
