Sorry I didn't post my solution earlier. Rick, I have to give you kuddos..you saved me a thousand dollars. It ended up being the solenoid pack. After replacing the solenoid pack and changing the tranny fluid again, it runs like new. You were right, every tranny person we talked to said that at our mileage, we were sure to need a new tranny. They even said that the solenoid pack "may" work for ten minutes, a month, or a few but eventually we will need a new tranny. Conveniently, this came from every tranny "salesman" in town.
Again, thanks for saving me so much money.
