<p>A valve and closure assembly for an automatic transmission has a cover plate (40) which can be attached to a transmission housing (14) to close off the interior of the housing from atmosphere. A separator plate (42) and a plurality of solenoid-operated control valves (44 to 56) are secured to the cover plate and disposed within the transmission housing, and fluid passages (68,70,72) in the cover plate interconnect the control valves. Passages in the separator plate direct fluid to passages (26,74,76) formed 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 (60) for the solenoids of the control valves, and also an electrical connector (58), are disposed on the cover plate so that a single electrical connection (62) to the transmission housing can be utilised. Filters (28) for both high-pressure control fluid and low-pressure cooling and lube fluid are secured on the cover plate.</p> |
