Trans @70k.. hanging on to dear life lol

Started hearing this today. Not the first time I heard it but it wasn’t as bad as this. Could it be bc of the cold weather? It’s been around 30 degrees lately. Also when it warms up, it goes away. I tested it when I turned the car off and back on, let it idle for a bit and it didn’t make the noise. It’s weird bc last winter it never made this sound after a cold start, but now this winter it’s starting to. Rn ig ima ride it out till it dies lol
