yes it's easy to remove, but also easy to fix it up yourself, maybe without taking it completely off, might just be slipped connections of the rods to the trans, start with taking the top off and clean and re-grease it - have someone carefully run the shifter and watch how it moves, look at the
notches and pawls for wear, should be fairly square corners, if too rounded they can be built up with a bit of weld and filed back to shape
