This is tough to explain, but it seems you are OK here if you are happy with the shifting.
The kick-down linkage needs to be far enough forward that you can feel the shifting, but not so far forward, that your engine is shifting at 3000 RPM.
There should be a way to play with the length of the rod, so you can experiment. I know from mine, just 1/4 inch makes a huge difference. Again, I think you are worried about nothing, but this is something you can play with in the future if you'd like.
