A transmission includes an input assembly, an electric machine, a variator and a power shift assembly. The input assembly has directional clutches and is configured to receive rotational engine input power. The variator has only a single planetary set configured and combine to receive rotational input power from the electric machine and the input assembly. The power shift assembly is configured to receive rotational power from the variator, and it includes speed gears, range gears and power shift clutches and an output shaft. The power shift clutches are configured to dissipate energy from asynchronous gear meshing. The power shift assembly is configured to effect multiple different rotational power flows through to the output shaft that arise from meshing gears at each shift to effect a unique one of multiple gear ratios.
