Valve Body
Repair
NOTE: This repair is only necessary if one or more ofthe valves in a valve body do not slide smoothly in theirbores. Use this procedure to free the varves.
'1. Soak a sheet of #600 abrasive paper in ATF forabout 30 minutes.
2. Carelully tap the valve body so the sticking valvedrops out of its bore. lt may be necessary to use asmall screwdriver to pry the valve free. Be carefulnot to scratch the bore with the screwdriver.
4.
Inspect the valve for any scutf marks. Use the ATF-soaked #600 paper to polish off any burrs that areon the valve, then wash the valve in solvent and dryit with compressed air.
Roll up half a sheet of ATF-soaked #600 paper andinsert it in the valve bore of the sticking valve.Twist the paper slightly, so that it unrolls and fitsthe bore tightly, then polish the bore by twisting thepaper as you push it in and out.
NOTE: The valve body is aluminum and doesn,trequire much polishing to remove any ourrs.
,l

5.Remove the #600 paper. Thoroughly wash theentire valve body in solvent, then dry it with com-pressed ar.
Coat the valve with ATF, then drop it into its bore, ltshould drop to the bottom of the bore under its ownweight. lf not, repeat step 4, then retest. lf the valvestill sticks, replace the valve body.
Remove the valve. and thoroughly clean it and thevalve body with solvent. DrV all parts with com-pressed air, then reassemble using ATF as a lubricant.
