Claim:
1. A variable transmission comprising: an input shaft coupled to a power source; a variator (CVP) comprising a first ring assembly drivingly engaged to the input shaft, a carrier assembly comprising a plurality of tiltable variator balls drivingly engaged with the first ring assembly, and a second ring assembly drivingly engaged with the tiltable variator balls; and a planetary gearset comprising a planet carrier coupled with the input shaft, a ring gear drivingly engaged with the second ring assembly of the variator, and a sun gear drivingly engaged with an output of a vehicle, wherein the variator is positioned between the power source and the planetary gearset in a transmission arrangement, wherein the variator speed ratio controls the flow of power from the power source through the ring gear of the planetary gearset wherein the planetary gearset is configured to split power of the input shaft between the variator and a mechanical path going directly to the output through the planetary gear set.
