Beschreibung
Zusammenfassung:	A drive assembly having a housing forming an internal sump for a transmission, and an accumulator chamber formed in the housing and in fluid communication with the sump. A piston chamber in the housing is in fluid communication with the accumulator chamber. The transmission includes a pump, a pump running surface and an internal porting system in a center section, and a pump swash plate. A piston divides the piston chamber into first and second portions. The piston is biased by a spring force to pressurize hydraulic fluid in the piston chamber and thereby pressurize the hydraulic fluid in the internal sump when pressure in the piston chamber decreases below a set level. A second transmission may also be located in the housing.
