A family of transmission gearing arrangements utilize one or two ball variators to establish a continuous range of speed ratios between an input and an output. In each case, the range of speed ratios includes an infinite ratio in which the output is stationary as the input rotates. In some embodiments having two ball variators, the outputs of the variators are combining using a planetary gear set. In other embodiments having two variators, the outputs of the variators are combined using clutches, which may be switchable one-way clutches.
