An automated sequential transmission, comprising:

• a shift fork moveable between a plurality of gear shift positions;
• a first drum operably coupled to the shift fork and configured to move between the one or more gear shift positions based on a control input;
• and
• a second drum at least partially encasing the first drum, the second drum operably coupled to the first drum and the shift fork, wherein the second drum is configured to slide axially between a first position and a second position relative to the first drum based on the shift fork encountering a block-out event.
