I noticed this post from a Shimano 3-speed hub owner who is having trouble with shifting the hub into 1st gear. She replaced the shifter and has tried different adjustments but is still having trouble with it. If the cable is moving to the correct position, perhaps there is a problem in the hub? Maybe needs a cleaning and regreasing?

There have been some improvements however as a result of this change. The gear changes are more consistent and there is not longer any “play” in the mechanism when I have selected fist gear. Previously, I would get third gear in either second or third gear position and that is no longer the case. I now get second gear in first and second gear position and third in third gear position. Also, the gears would sometimes spontaneously change and that no longer happens.
The adjustment is perfect, and I have tried different positions of the indicator in the adjustment window to see if it made any difference but it does not.At the suggestion of some readers on here I had considered getting an old vintage thumb shifter and adapting it but discarded that idea as it seemed there was no knowing whether they would be compatible.
