So after about 60 miles or so the slipping and sticking came back. Added another 2 qts and life was good.
I've had to add ATF every 60-75 miles. I've probably added 8-10 qts, which I assume is more than it holds, so all the fluid in the system should be new fluid.
My problem is that I can't figure where it's leaking. It's not leaving any wet spots under the car and everything else under there is bone dry. Seems like a lot of fluid to loose so quickly w/ no traces....
Where is my ATF going?

If the modulator were defective, sucking fluid into the engine, you would see white smoke coming from the exhaust. I would check the radiator overflow tank for a strawberry color, which is transmission fluid mixed with coolant = faulty radiator.
