Abstract
A transmission oil pan module includes an oil pan having a floor formed with a drain hole and side walls extending from the floor to provide a space for holding oil. A filter assembly includes a housing disposed in the space of the oil pan. A drain tube extends from the housing through the drain hole to a free end exterior of the oil pan. The drain tube has an oil inlet open to the space of the oil pan and is formed with an oil outlet adjacent the free end of the drain tube. A drain plug is removably disposed in the outlet for normally closing the outlet to retain the oil, and upon removal, permitting the oil from the pan to drain through the drain hole.
