Where is the trans leaking? Could the noise be coming from ATF getting on the accessory belts?

Yep, the main serpentine drive belt can cause this issue. I would use a flashlight and open the hood for inspection. Here is how to change the belt out which if is worn out will cause this noise. Also, check the tension on the belt tension as well, it could be weak and causing the issue. Please upload pictures or videos in your response of any problems so we can see what to help you with.
