I've never seen one that could be shifted without assisting by clocking the spindle with the other hand. Sometimes they go right in but not very often. Similar to shifting even a manual transmission in a car with the engine off. Some gears are synchronised and some are not.

If you have a VFD, use the "jog" function and pneumatic cylinders to
operate the shift handle.
I use a VFD on my lathe, and the VFD's jog function works great for
shifting.
