Oil sump arrangement with integral filter and heat exchanger

An arrangement for treating oil circulated in a drive train including an engine, a transmission, a coolant source and a sump pan having side walls and a horizontally extending floor, the sump pan including a fluid suction tube for returning liquid pooled on the floor to the drive train, the arrangement comprising:

• a panel adapted to be removeably disposed in the sump pan in spaced relation to the floor and adapted to divide the sump pan into a first chamber and a second chamber, the panel having an upstream surface adapted to face into the first chamber and a downstream surface facing into the second chamber and the panel having at least one opening therethrough for connecting the two chambers,
• a filter media integral with the panel disposed in the opening, through which filter media the liquid flows for pooling in the second chamber to be returned to the drive train by the suction tube;
• and
• a heat exchanger integral with the panel and disposed on the upstream surface of the panel for cooling oil prior to the oil passing through the filter media.
