1. Thoroughly clean exterior of transmission.
2. Remove nut, lock washer, washer, O--ring, solenoid
coil and O--ring from solenoid valve stem. For assembly
purposes, note that "KANZAKI" molded into the coil has
the "I" nearest the nut location as coil direction is impor-
tant for proper solenoid operation.
3. Remove solenoid valve stem from transmission
pump body.
4. Remove pin from spool. Remove spool, sleeve and
solenoid valve spring from transmission pump body. For
assembly purposes, note that step in spool is toward
spring location and that sleeve is installed so that holes
are closest to the spring location as well.
