What is claimed is: 1. A bag filter assembly for filtering a liquid used in a transmission or engine, comprising: a media bag comprising at least one piece of filtering material, the bag forming a substantially flat bag envelope having an inside, an outside, a substantially flat top portion, a substantially flat bottom portion, and an outlet portion on the top portion, the outlet portion further comprising an outlet tube and an outlet seal disposed on the outlet tube, the outlet portion configured for attachment, directly or indirectly, to a transmission or engine filter outlet portion; a spacer segment that joins at least one edge of the top portion and the bottom portion; and a support structure positioned inside of the bag envelope between the top portion and the bottom portion maintain an internal space between the top portion and the bottom portion wherein the support structure comprises ribs. 2. The bag filter assembly of claim 1, further comprising a filter bag outlet configured at a first end to connect directly or indirectly to a transmission pump or engine oil pump, and attached at a second end to the bag at the outlet portion. 3. The bag filter assembly of claim 1, wherein the filter media is a single piece of filtering material folded upon itself and sealed to form a media joint. 4. The bag filter assembly of claim 1, wherein the support structure comprises a material chosen from a pillow-shaped porous body, expanded metal, and a plastic flattened tube with holes. 5. The bag filter assembly of claim 1, wherein the media bag further comprises a spacer having a top side and a bottom side, wherein the filter media further comprises a first piece and a second piece of filtering material, and wherein the first piece of filtering material is sealed to the top side of the spacer and the second piece of filtering material is sealed to the bottom side of the spacer. 6. The bag filter assembly of claim 5, wherein the spacer is integral with the support structure. 7. A transmission or engine filter for filter a liquid, comprising: a transmission or engine filter housing, wherein the housing comprises an oil pan attached to a filter upper cover, and includes an intake port and an outlet port; and, a filter bag assembly comprising, a media bag comprising at least one piece of filtering material, the bag forming a substantially flat bag envelope having an inside, an outside, a substantially flat top portion, a substantially flat bottom portion, and an outlet portion on the top portion, the outlet portion further comprising an outlet tube and an outlet seal disposed on the outlet tube, the outlet portion configured for attachment, directly or indirectly, to a transmission or engine filter outlet portion; a spacer segment that joins at least one edge of the top portion and the bottom portion; and a support structure positioned inside of the bag envelope between the top portion and the bottom portion maintain an internal space between the top portion and the bottom portion wherein the support structure comprises ribs, and wherein the filter bag assembly is positioned at least partially within the housing to form an outside-in flow scheme. 8. The transmission or engine filter of claim 7, wherein the filter bag outlet is aligned with the outlet port, and the filter bag outlet and the outlet port are sealed together. 9. The transmission or engine filter of claim 8, wherein the filter bag assembly further comprises an outlet tube attached to the filter bag outlet. 10. The transmission or engine filter of claim 9, wherein the outlet tube is coincident with the outlet port and is sealed to the outlet port. 11. The transmission or engine filter of claim 10, wherein the outlet port further comprises a fixing ring and the outlet tube extends into or through the fixing ring and is sealed against the fixing ring. 12. The transmission or engine filter of claim 7, wherein the oil pan and the upper cover comprise a plastic material. 13. The transmission or engine filter of claim 7, wherein the transmission or engine filter has a composite construction. 14. A transmission or engine filter for filtering liquid, comprising: means for filtering fluid a media bag comprising at least one piece of filtering material, the bag forming a substantially flat bag envelope having an inside, an outside, a substantially flat top portion, a substantially flat bottom portion, and an outlet portion on the top portion, the outlet portion further comprising an outlet tube and an outlet seal disposed on the outlet tube, the outlet portion configured for attachment, directly or indirectly, to a transmission or engine filter outlet portion; means for joining at least one edge of the top portion and the bottom portion; means for supporting, positioned inside of the bag envelope between the top portion and the bottom portion to maintain an internal space between the top portion and the bottom portion wherein the support structure comprises ribs; and a means for housing the fluid filtering means, wherein the housing means and fluid filtering means are configured together to form an outside-in flow scheme. 15. A method of making a suction-side transmission or engine filter for filtering a vehicle liquid, comprising: positioning a filter bag assembly on an oil pan, wherein the filter bag assembly comprises a media bag having at least one piece of filtering material, the bag forming a substantially flat bag envelope having an inside, an outside, a substantially flat top portion, a substantially flat bottom portion, and an outlet portion on the top portion, the outlet portion further comprising an outlet tube and an outlet seal disposed on the outlet tube, the outlet portion configured for attachment, directly or indirectly, to a transmission or engine filter outlet portion, and a support structure positioned in side of the bag envelope between the top portion and the bottom portion to maintain an internal space between the top portion and the bottom portion wherein the support structure comprises ribs; joining a spacer segment to at lease one edge of the top portion and the bottom portion; positioning an upper cover having an outlet port over the filter bag assembly to align the outlet port and the outlet portion; welding the upper cover to the oil pan filter; and sealing the outlet port and the outlet portion together.
