Abstract
A method of operating a multi-mode drive system that precisely orchestrates a shift between gear ratios in a power take off unit and a rear drive module. The method first shifts between gear ratios in the power take off unit and then, depending upon the success or failure of the shift of the power take off unit, shifts between gear ratios in the rear drive module.
