ABSTRACT:
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 (GR.sub.T) due to engine speed remaining less than the synchronous engine speed (ES=OS*GR.sub.T) 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 (GR.sub.DMT <ES.sub.MAX .div.OS), synchronizable at achieved maximum engine speed (ES.sub.MAX), is identified and caused to be engaged.
