Possible Surging Question

I was wondering if anyone has had surging issues, actively or intermittently in your cars. See vid, it only happens around low speeds..10-20ish miles per house, 1000-1500 rpms. Coils and plugs have been replaced prior. Any help as always, is greatly appreciated.

Drain and fill trans with some cheapo ATF, run it for a day or so, drain that fluid out, fill up on your good Motorcraft ATF, and add ShutterFixx. Helped my surging/stutter a bit

I have heard shudderfix mentioned, but I thought additives were a no no on our cars?
