They did change the oil at the dealer. The problem began ever since they replaced the radiator. Thanks!

Is there any service that was performed at the time that may help diagnose this issue? Was it just a fluid and filter change on the transmission, or did they flush the system? Was it done the same time that the radiator was changed? Did they happen to itemize on the bill what type (not brand) of transmission fluid they used? Did they perform and PCM updates?

So they used a flush machine. There is your problem. Flush machines kill transmissions. The transmission should never be flushed. Its ok to do a dynamic fluid exchange, but thats not the same thing as a flush. Flushes force dirty fluid through the valve body at pressures the transmission was never intended to see. They blow out seals, and jam crud into the small passages.

Exactly my thoughts, and the cause of my leading questions. I suspect the flush contributed to the issues you're now experiencing and I'm sadly unsure of the best course of action for you at this point.

KhanTyranitar, I think I will go with the second option (DFE) It was performed at the Ford dealership, I'm assuming it was done properly! I'm calling the dealer as i type. The company's name for the machine is BG machine! The guy is telling me it is used across the country. He tells me to bring it in. Thanks!!
A dynamic fluid exchange using nothing more than a simple pump that adds new fluid to the reservoir, while the transmissions own internal pump pumps the old fluid out through the transmission cooler return lines. This type of exchange is only performed after the pan has been dropped and the filter replaced.

Nope, a dynamic fluid exchange doesn't use a machine. If a machine was used then it was flushed. Even at the dealer, they often use flush machines. BG is a flush machine, as guilty as the rest.
