engine whine when accelerating

about a week ago i posted a thread and it said that i had a some wierd type of engine whine, when i accelerate, and someone thought it could be a part in the tranny. i took it to the dealership and they said that they could not find anything, but the whine is still there? is it something simple? what should i do?

Just my two cents but it could be your power steering pump. They're known to make a whining sound in these GP's. Mine does.
