Abstract
A ratio shift control system for an automatic transmission calculates the magnitude of a difference in temperature between a detected engine coolant temperature and a detected outside air temperature, which are detected by coolant and outside air temperature sensors, respectively, during one engine start of an internal combustion engine. Ratio shift in the automatic transmission is controlled based on the detected outside air temperature during the one engine start when the magnitude of the difference in temperature is equal to or less than a predetermined cold engine evaluation threshold.
