Lock for shifter when in sequential mode

This piece is for the famous shifter that we can found on internet that has a H pattern and that can be use as sequential mode.To use in sequential mode we must slide down a piece that prevent lateral movement.When playing this piece always goes up and the the sequential mode doesn't work.I have designed a lock that prevent that movement.It's tight so that it stays in place but we can remove it manually to use the H pattern.
