A hydrostatic transmission including a variable displacement pump including an input shaft and a pump cylinder barrel rotatably coupled to the input shaft, the pump cylinder barrel having a plurality of cylinder chambers arranged in parallel with other and distributed about the input shaft axis of rotation. Each cylinder chamber has a reciprocating piston therein which bears against a pivotable swashplate, the displacement of the pump being varied in response to changes in the position of the swashplate. A gerotor motor is attached to the pump and has an output shaft. The motor includes an engaged pair of inner and outer members, the outer member being eccentric relative to the inner member. The inner member is rotatably driven relative to the outer member by fluid received between the inner and outer members from the pump, the inner member being drivingly connected to the output shaft. A plurality of fluid conduits extend between the pump to the motor, through which the motor is in fluid communication with the pump.
