11. Test the ATF strainer by pouring clean ATF through the inlet opening, and replace it if it is clogged or 

damaged.

VALVE BODY REPAIR 

1. Soak a sheet of # 600 abrasive paper in ATF for about 30 minutes.  

2. Carefully tap the valve body so the sticking valve drops out of its bore. It may be necessary to use a small 

screwdriver to pry the valve free. Be careful not to scratch the bore with the screwdriver. 

NOTE:

This repair is only necessary if one or more of the valves in a valve body do not 
slide smoothly in their bores. Use this procedure to free the valves.

3. 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 air.  

4. Roll up half a sheet of ATF-soaked # 600 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. 

NOTE:

The valve body is aluminum and doesn't require much polishing to remove 
any burrs.
