Abstract
A control method/system for controlling range section (14) shifting in a range-type transmission (10) having a "repeat-H" (200) or "double-H" (202) shift mechanism. Under certain conditions, a shift into an operator-selected target ratio (GR.sub.T) is unacceptable and a shift into an alternate ratio (GR.sub.ALT) is implemented. The alternate ratio is a ratio available at an operator-selected main transmission position (1/5, 2/6, 3/7, 4/8) with the range section in a range ratio not selected by the operator.
