Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method and a system of controlling up-shift operation of an improved mechanical automatic transmission for a vehicle. SOLUTION: By sensing a vehicle operation state representing the change of a vehicle load, a control parameter valve (GCWCP) representing gross combination vehicle weight is reset to form a filter value and an average value, and a given default value is decided. In a such a system and a method, a mechanical automatic transmission for a vehicle is controlled as a function of a control parameter value. A default value is comparatively higher compared with an estimated range of actual gross combination vehicle weight. A multistage skip up-shift having an inter-stage ratio of 50% or more is prohibited until a control parameter value is changed after resetting.
