Abstract
An automatic transmission for an alcohol engine is upshifted in accordance with one of first and second shift patterns. The transmission is upshifted at a higher vehicle speed in accordance with the first shift pattern, and the transmission is upshifted at a lower vehicle speed by the second shift pattern. Concentration of the alcohol is detected by an alcohol concentration sensor. The second shift pattern is provided when the detected alcohol concentration is higher than a reference value.
