A two-stage, continuously variable transmission used to power a machine, incorporates self-adjusting features while ensuring a positive engagement. Power from an engine is transferred via a rotatable shaft of a first stage, which engages with a first stage differential gear. The first stage gear delivers power to each of (1) a low ratio and (2) a high ratio first stage output half shafts. A second stage includes each of (1) a low ratio and (2) a high ratio second stage input half shaft. The low ratio half shafts are engaged providing a first pathway. The high ratio half shafts are engaged providing a second pathway, both shafts in positive engagement. A second stage differential gear receives low and high gear ratio power simultaneously, over the first and second pathways and aggregates the power to be output at an automatically selected optimum gear ratio for the machine, determined by the kinetic status of the machine.
