Got Notchiness?

Two copper washers can fix this.

I've seen that before. One of the potential drawbacks is it can cause it to pop out of gear. Easy enough to undo if you don't like it though.

I'm going to assume that would happen more often with 2 washers in. So you can at least try it in stages.

They are a little but there is a detente in the transmission to help hold it in gear. This mod lessens the detente pressure
