Zusammenfassung:	A control method/system for controlling engagement of reverse ratios in automated vehicular transmission systems (10) having a controller (38) issuing command output signals to non-manually controlled actuators (30, 34) is provided. The controller includes logic rules for (i) sensing predetermined reverse ratio enabling conditions, including remaining in neutral for at least a predetermined period of time (NT > REF2) prior to selecting reverse, and (ii) issuing commands to cause a reverse ratio to be engaged only upon sensing such conditions, to minimize accidental engagement of reverse ratios without requiring mechanical interlocks.
