Abstract
A transmission filter includes two outlets. One outlet, adapted to feed an engine-driven pump, protrudes diagonally from the front of the filter. The first outlet is sealed to the inlet of the engine-driven pump by a radial seal. The second outlet is arranged in a rear extension and is sealed to the inlet of an electric pump by a compression seal. The differing types of seals and relative orientations of the outlets make the assembly less sensitive to dimension variation due to production and assembly tolerances. The relative locations of the outlets also mitigate any flow interactions between the pumps when both operate simultaneously.

A transmission comprising:
- a filter having a bottom surface defining a filter inlet, a top surface defining a rear outlet hole, and a front outlet tube projecting from a front end at an oblique angle relative to the top surface;
- an engine driven pump having an inlet sealed to the front outlet tube by a radial seal installed in a section of the front outlet tube that projects from the front end at the oblique angle;
- and
- an electric pump sealed to the top surface around the rear outlet hole by a compression seal.
