Somehow I have acquired a Claron-G 150mm f/9 lens in a Seiko f/6.3 shutter. I have only used it a few times but it seems to work fine.
What if any is the problem with this?

Generalizations are made because they are Generally true...
The aperture scale will be incorrect.
If it works fine for you just leave it and have fun with it.
I've always been told that its important for the shutter to be shimmed to its lens elements. My guess is that this isn't as important for film as it is an 80 megapixel digital back, but I've got to think it would throw something off at least a little. Am I wrong here?
It should not be important on reasonably modern lenses - shutters for photographic taking lenses have been in a small set of standard sizes for many decades, and all reasonable makers have negligible production tolerances for the body strength. If there are shims, they generally go with the LENS, not the shutter, as there is more variability in lenses, where small tolerances in the elements might add up or even multiply. Beware, there are a few shutters (mostly for fixed installation) that came in identical width and thread pitch as some common type, but have a different strength.
The lenses, yes. But hardly ever the shutter. If you transplant whatever shims you found with the lens, you'll be fine. If there are none, it either doesn't need them, or they would be missing on any shutter.
