Abstract

An example hydrostatic transmission includes (i) a motor section having a motor interface; (ii) a pump section configured to generate fluid flow, where the pump section comprises a pump interface having a first pump port to provide fluid flow therethrough and a second pump port to receive returning fluid flow therethrough; and (iii) an interface block coupled to the motor interface and coupled to the pump interface so as to couple the pump section to the motor section, where the interface block includes internal fluid passage to facilitate fluid communication between the pump section and the motor section.
