Abstract:
1. A transmission comprising: a transmission case having a first wall and a second wall perpendicularly mounted to the first wall, wherein the first wall rotatably supports a drive sprocket and a driven sprocket, and wherein the second wall has a mating surface; a housing having a fluid pump, for pumping lubrication fluid, and a torque converter mounted for rotation therein, wherein the housing further includes a mating surface, and a gasket, and wherein the gasket is disposed between the mating surface of the second wall of the transmission case and the mating surface of the housing to form a seal; a torque transfer member coupled to the drive sprocket and to the driven sprocket for transferring a driving torque from the drive sprocket to the driven sprocket; a first baffle mounted to the housing, wherein the first baffle has a planar base, a first arcuate flange extending from a first side of the base, a planar flange extending from a second side of the base and a sealing lip formed in the planar flange; a second baffle mounted to the first wall of the transmission case, wherein the second baffle has a planar base having a first side surface; and wherein the sealing lip contacts the first wall of the transmission case to form a seal to enhance the flow of lubrication fluid around the torque transfer member.
