5.7 engine 4l80e trans.
She starts up fine but about a minute after starting while sitting, she makes this medium pitched WWhhheeee noise from the back of the engine/transmission area. It starts and stops abruptly and doesn’t return until started again.
No shifting issues or power loss. No rough idle.
There’s no indication anything is wrong other than that funny noise.
What am I hearing here and am I supposed to be hearing it?
