A method for controlling a continuously variable transmission of a work machine during a shuttle shift is disclosed. The method may generally include initiating a directional swap by disengaging an off-going directional clutch of the continuously variable transmission and slipping an on-coming directional clutch of the continuously variable transmission to decelerate the work machine in an off-going direction. In addition, the method may include estimating a total amount of energy to be dissipated in the on-coming directional clutch during the shuttle shift, comparing the total amount of energy to a predetermined energy threshold and, if the total amount of energy is equal to or exceeds the predetermined energy threshold, performing the reversion action to complete the shuttle shift, wherein the reversion action corresponds to an action taken to engage one of the off-going directional clutch or the on-coming directional clutch so as to permit the shuttle shift to be completed using ratio changing.
