Abstract: A motor vehicle 10 includes a hydromechanical powersplit transmission 11, a prime mover 13, an engine drive shaft 14, drive wheels 15, a differential 16, a differential drive shaft 17, and frame rails 18. The transmission 11 includes a connecting plate 25 having a hydraulic side 25a with a pressurized hydraulic chamber 36 filled with hydraulic fluid and a gear set side 25b with an atmospheric pressure gear side chamber 37 partially filled with lubricating oil. The connecting plate 25 provides a hydraulic manifold. A prime mover input shaft 41, 62 extends through the hydraulic chamber 36 and connecting plate 25 and is drivingly connected to one of the planetary gear components 71. Hydraulic pump motor units 42, 43 include hydraulic pump motor unit drive shafts 44, 45 that extend through connecting plate 25 and are drivingly connected to planetary gear components 71.
