Same thing happened to me. It was the transmission filter… or more precisely, the little O-ring seal where the flat filter goes into the tranny case. It was sucking air. I damage the new one and re-used the old one. Tap the new one in with a socket, making sure it goes in straight and unblemished. Youtube videos.

And since you said you replaced the transmission fluid…. I suspect the same issue.

Easy fix (thankfully).

I never reved it as high as you, but essentially you have no pressure
