A filter (10) for filtering debris out of the fluid in a transmission sump (S) prior to the fluid entering a transmission pump (P) is disclosed. The filter (10) includes a filter housing (12) presenting a filter inlet (30), a bypass inlet (32), and an outlet (46). Filter media (14) is disposed in the housing (12) such that fluid flowing from the filter inlet (30) to the outlet (46) passes through the media (14) and fluid flows from the bypass inlet (32) to the outlet (46) without passing through the media (14). A bypass valve assembly (16), shiftable into and out of a closed position, prevents fluid flow through the bypass inlet (32) when the valve (16) is closed.

1. A transmission fluid filter comprising: a filter housing presenting a filter inlet, a bypass inlet spaced from the filter inlet, and an outlet spaced from the inlets; filter media in the housing such that fluid flowing from the filter inlet to the outlet passes through the media and fluid flows from the bypass inlet to the outlet without passing through the media; and a bypass valve associated with the bypass inlet, said valve being shiftable into and out of a closed position in which fluid flow through the bypass inlet is prevented, said bypass valve including a valve seat and a valve body positionable in sealing engagement with the valve seat when the valve is in the closed position, said bypass valve being yieldably biased into the closed position, said body having positioning tabs perimetrically disposed and cooperating with the valve seat to position the body on the seat when the valve is in the closed position said bypass inlet being defined about a bypass inlet axis and said outlet being defined about an outlet axis, said axes being at least substantially parallel and at least in close proximity to one another. 2. A transmission fluid filter comprising: a filter housing presenting a filter inlet, a bypass inlet spaced from the filter inlet, and an outlet spaced from the inlets; filter media in the housing such that fluid flowing from the filter inlet to the outlet passes through the media and fluid flows from the bypass inlet to the outlet without passing through the media; and a bypass valve assembly shiftable into and out of a closed position in which fluid flow through the bypass inlet is prevented, said bypass valve assembly including a projecting valve seat and a valve body shiftable in a first direction into and out of sealing engagement with the valve seat, said valve body including a first positioning element extending toward the valve seat and cooperating therewith to restrict movement of the valve body in a second direction, wherein the first and second directions are at least generally unparallel to one another, said bypass valve assembly including a lug in an opposed relationship with the valve seat, said valve body including a second positioning element projecting oppositely relative to the first positioning element, said second positioning element extending toward the lug and cooperating therewith to restrict movement of the valve body in the second direction, each of said positioning elements comprising a plurality of spaced apart tabs. 3. In a powered vehicle including a lubricated transmission having a transmission sump and a transmission pump, a fluid filter fluidly interposed between the sump and the pump, the filter comprising: a filter housing presenting a filter inlet, a bypass inlet spaced from the filter inlet, and an outlet spaced from the inlets; filter media in the housing such that fluid flowing from the filter inlet to the outlet passes through the media and fluid flows from the bypass inlet to the outlet without passing through the media; and a bypass valve assembly shiftable into and out of a closed position in which fluid flow through the bypass inlet is prevented, said bypass valve assembly including a projecting valve seat and a valve body shiftable in a first direction into and out of sealing engagement with the valve seat, said valve body including a first positioning element extending toward the valve seat and cooperating therewith to restrict movement of the valve body in a second direction, wherein the first and second directions are at least generally unparallel to one another, said positioning element comprising a plurality of spaced apart tabs.
