Bad bushings in the 915 shift assembly is the #1 problem with it. Otherwise the shifter is very simple, very effective. I had mine apart recently and I am amazed at the simplicity of this shifter. It's really quite ingenious when you look at how it works.

As long as your replacing both the ball socket cup bushing and the shift rod guide bushing, you should have everything you need for the shifter itself to operate properly. In terms of getting it to shift right, the coupler and it's alignment are key to making the shifter tell the transmission which gear you want.
