A downshift control for a manually shifted transmission (10) is provided. The control senses vehicle ground speed (100) and compares same to predetermined maximum values (REF1, REF2) at which certain ratios are allowed to downshift engaged. If vehicle speed exceeds the reference (OS > REF), a blocking plunger (216) assumes a position (216B, 216C) wherein selection of the prohibited ratio(s) is automatically mechanically blocked. <IMAGE>
