    摘要: A method of controlling an automatic transmission of a machine includes a step of identifying an upcoming gear ratio change from a current gear ratio to a proposed gear ratio. An estimated power output value, based on the proposed gear ratio and a current engine speed, is determined. The estimated power output value is adjusted based on a derated operating condition. If the estimated power output value is greater than or equal to a current power output value, a gear evaluation identifier is set to a first value. If the estimated power output value is less than the current power output value, the gear evaluation identifier is set to a second value.
