Transmission Shudder Problems of Chrysler 200

My original transmission was replace once, approx. (1) year after purchase. Since then there have been several revisits with the dealer to check the transmission for erratic shifting and free wheeling down hills. They have upgraded the firmware because they had issues that I have been experiencing. When travel at 25 mph the transmission will vibrate when shifting from 4th to 5th and back to 4th. When I come to a hill at 25 mph in 5th gear, it will coast then upshift to 6th (with vibrations). At 59 mph in 8th gear the car vibrates up to approx. 63 mph. Chrysler customer assistance center were working with me until I expressed I need something to be done (not feeling safe in this car), they now are stating (frank-customer service supervisor) that because the dealer who inspected the vehicle (did not allow me to ride with him when he did a test drive), cannot find anything wrong, the case will be closed. I received a communication stating that the case is closed as of 6/20/16. It is very apparent that Chrysler is now in a damage control since I asked to speak with a "Chrysler representative", frank suggested that I would not be allowed to speak to him because they do not deem the issue to warrant such a conversation. He also suggested that if I wanted a second opinion from another dealer, I would have to pay for the service cost. Frank also wanted to know who told me about the "Chrysler representative"? I do not feel safe driving a car that vibrates and free wheels at low speeds and high speeds. It is very obvious there is an issue and Chrysler wants me to go away.
