A power transmission having both mechanical and hydraulic power paths to a simple planetary differential unit to provide a double hydro-hydromechanical transmission with a low-speed, high torque, hydrostatic drive range by causing counterrotation of two gear members of the simple planetary, an intermediate speed range hydromechanical drive with inputs to the differential from both power paths and a high-speed, hydrostatic drive range.
