The "too highly trained" part is mostly a question of motivation. If you already understand the patterns complete pushing all the concrete instantiations of the pattern into the unconscious (i.e. rote memorizing to complete fluency) looks just too much pain to be worth the effort when you already know it.

I'm just plying a few piano pieces for christmas and such and do not have much need for sight reading much less transposition. My solution therefore is to just memorize the actual notes skipping the sight to finger step altogether. My pattern memory is good enough to read the scale a few times and memorize the complete piece. Simplifies playing it in any case.
