ABSTRACT:
A valve and closure assembly has a cover plate which attaches to a transmission housing to close the interior housing from atmosphere. A separator plate and a plurality of fluid valve assemblies are secured to the cover plate and disposed within the transmission housing. Fluid passages in the cover plate interconnect the valve assemblies. Passages in the separator plate direct fluid to passages in the transmission housing at the interface of the cover plate and transmission housing for distribution within the transmission housing to components disposed therein. Electrical wiring for the solenoids and an electrical connector are disposed on the cover plate so that a single electrical interconnection with the transmission can be utilized. Filters for both high pressure control fluid and low pressure cooling and lube fluid are secured on the cover plate.
