Does it rattle or clunk? If it is a rattle, check the heat sheild on the cat and the manifold. At certain rpms, the motor will vibrate more or less, and at 2700 it might cause the sheilds to vibrate. Just a guess, though.

old age + frequencies?
meaning: old cars naturally develop loose things, and maybe at exactly 2700 the engine is vibrating at the right frquency to make those loose things scream it up.
Does he feel the vibration in the shifter if he puts his hand on it?
