Unexplainable Transmission Stutter... help?

I'm going to disconnect the external trans cooler, and see what happens when the trans lines are only hooked up to the radiator. I had an external cooler before, and hooked this new one up the same way as the old one, this new one is just a touch bigger than the old one.

Ok
I have done all I can unless there is new information beside pulling the pan and filter.
You are just wasting your time doing anything else.
