Beschreibung
Zusammenfassung:	A method and system for controlling downshifting of an automated mechanical transmission system which senses unsuccessful attempts to engage a predetermined downshift target gear, ratio (GRT) due to engine speed remaining less than the synchronous engine speed (ES = OS*GRT) for engaging said target gear ratio and, in response to sensing such conditions, automatically initiates a degraded mode of operation wherein an achievable degraded mode target gear ratio (GRDMT < ESMAX , OS), synchronizable at achieved maximum engine speed (ESMAX), is identified and caused to be engaged.
