Abstract
An oil reservoir for a vehicle transmission includes a separately formed oil pan and suction tube each formed of plastics material. A filter cartridge is disposed about a lower end portion of the suction tube to filter oil entering an oil inlet of the suction tube at the lower end. The suction tube and floor of the oil pan have snap-together connecting structure. To assemble the suction tube with the floor of the oil pan, the tube is simply pressed toward the pan causing the connecting structure to engage with a snap-fit connection.
