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 DaDer in ATF for
about 30 minutes.
2. Caretully tap the valve body so the sticking valve
drops out of its bore.
CAUTION: lt may be necessary to use a small
scrawdriv6r to pry the the valve f.66. Bs caloful not
to sciatch th€ bole with th6 scrowdriver.
Remove the #600 paper and tho.oughly wash the
entire valve body in solvent, th€n dry with com-
pressed air.
Coat the valve with ATF then droD it into its bore.
It should droD to the bottom of the bore under its
own weight. lf not, repeat step 4 then retest.
lf the valve still sticks, replace the valve body.
InsDect the valve for anv scuff marks. Use the ATF-
soaked # 600 paper to polish ofl any burrs that are
on the valve. then wash the valve in solvent and drV
it with compressed air,
Roll up halt a sheet ot 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 thepaper as you push it in and out.
CAUTION: The valvs body is aluminum and doesn't
require much polishing ro lomovo any bulla.
