Abstract
The inventive transmission has at least two different shift modes for shifting between the same two gear ratios. A control unit electronically senses various vehicle conditions and based on this information selects the appropriate shift mode suited for the particular driving situation. The transmission then shifts from one gear ratio to another based on this selection.
