A control for confirming disengagement of a disengaging gear ratio (GR). Signals indicative of input shaft speed (ES or IS) are compared to signals indicative of output shaft rotational speed (OS) to determine if the quotient of input shaft rotational speed to output shaft rotational speed (IS/GR) remains outside an increasing-sized window (GR -/+ error, GR -/+ 2*error, GR -/+ 3*error).
