Abstract: An air filter comprises a rigid, hollow body that may be spherical, cylindrical, rectangular or shaped to conform to available, typically underhood, space. If spherical, it may be .assembled from a first, lower hemisphere and a second, upper hemisphere which are secured together about their edges, by, for example a press or interference fit, an O-ring received within complementary, edge adjacent channels, an adhesive or autogenous bonding. Other shapes and configurations may be assembled from a body with, for example, a solid bottom and attachable lid, top or cover. The hollow body is filled with activated carbon filter media or passive fibrous filter media. The upper hemisphere, lid or cover includes an outlet and cap which reduces the possibility of ingesting water into the filter. The lower hemisphere or body includes an inlet fitting to which a hose leading to an outlet or vent in the powertrain component is attached.

Abstract: A transmission having a pressure controlled vent system, including a vent tube configured to engage a transmission such that a first opening of the vent tube is in fluid communication with an upper portion of a transmission cavity, a second end defining a second opening configured to be in fluid communication with an external atmosphere, and a bifurcated portion between the first end and the second end. The bifurcated portion includes a first tube segment and a second tube segment in parallel with the first tube segment. A pressure relief valve disposed in-line within the first tube segment and a vacuum relief valve disposed in-line within the second tube segment. The pressure relief valve cooperates with the vacuum relief valve to maintain a predetermined range of pressure differential between the first opening and the second opening. The vent tube may also include a moisture and/or a transmission fluid separator.
