I'll check the lines after work. I did notice during my oil change 2 weeks ago that there seemed to be more than usual amounts of fluids/grease/crap on the bottom of the transmission pan.

Guy at the shop seems to think from my description that it's a solenoid problem and needs to go to a tranny shop. He said the service could just be waste of money. I elected to do the service anyways because I don't have the time to leave it with a tranny shop before I start the move. Better off to have new filters and fluid than to do nothing. Tomorrow I'll be making the first trip hauling a trailer down to Augusta.

I'm also going to replace the TPS. Some people over on Jeep Forum seemed to suggest that it could cause symptoms similar to that.
