ABSTRACT:
A system/method of resetting the value of a control parameter (GCW.sub.CP) indicative of vehicular gross combined weight and determined as a filtered/averaged value, to a predetermined default value upon sensing vehicle operating conditions deemed indicative of a change in vehicle loading. A vehicle automated mechanical transmission system is controlled as a function of the value of the control parameter. The default value is relatively high compared to the expected range of actual vehicle gross combined weight. Large skip upshifts, greater than 50% ratio step, are prohibited after a reset until the control parameter value is verified.
