ABSTRACT:
A replacement solenoid switch valve assembly for an automatic transmission system is disclosed. The switch valve assembly includes a switch valve member, which acts in conjunction with an interlocking valve disc set. The disc set is configured for reciprocating movement in tandem and also enables axial shifting movement of the discs relative to one another to support the functions of the solenoid switch valve assembly. This is accomplished by providing an axial stem which projects in perpendicular relation from a first disc. A mating hole in the second disc is radially disposed on the stem in sliding engagement thereon effectively interlocking the discs in alignment. In an installation method of the present invention, the tandem disc set is provided in standard size as a drop-in replacement for valve bodies that do not exhibit excessive bore wear and also in an oversize embodiment for valve bodies showing excessive wear.
