I looked at the 9249 manual... and I pulled the cover off and took a photo of this one:
In the top right you can see the shift fork, and it moves well and engages either the gears behind it (threading leadscrew) or the gears below it (power feed). That seems to all work well.
What doesn't make sense is that with both shift levers disengaged like this, power is fed through the shaft above the shift levers. I would've assumed that there were two separate shafts, left and right, and that power would only be fed through the shaft that the shift levers ride on from the left to the right, but that doesn't seem to be the case. The G9249 isn't set up like this, not exactly, at least.
