05 Avalanche Intermittent transmission whine

2005 Avalanche 1500 4L60E transmission noise. I’m hoping someone can help me out here. Tranny just started making a whining noise that comes and goes only when up to temp at low speeds, no noise when it’s cool. It changes with rpm and I heard it once after idling for a while.
