A hydrostatic transmission having a fluid pump (15), and a fluid motor (17) disposed in a housing (11) which is in fluid communication with a source (C) of low pressure fluid. The housing (11) defines a recessed area (71,85) and disposed therein is a piece of filter material (83,87), the recessed area intersecting the flow path through the transmission at a location between the low pressure source (C) and an inlet (65) to the pump (15). The flow area of the recessed area is substantially greater than that of the flow path through the transmission. The piece of filter material (83,87) is attached directly within the recessed area (71,85) in a manner sufficient to maintain the filter material therein during flow through the flow path. The invention provides substantial filter capacity without adding to the overall size or cost of any of the transmission components.
