A family of hybrid electric transmission arrangements share a common center housing, rear housing, two electric machines, power-split planetary gearset, and torque multiplication gearset. One arrangement additionally utilizes an overdrive gearset and an overdrive clutch. Another arrangement additionally utilizes two clutches and a brake to implement three operating modes. Since the components that differ between the two arrangements use the same general packaging space and all shift elements are hydraulically controlled via a front housing, the design of the front housing is also similar.
