If I remember from your other post you mentioned that you and T will be meeting together 3 times with new T for the transition. I am fairly sure current T and new T have probably discussed this transition and how hard this is going to be for you. This first session is in old T's office so you can feel more comfortable.
I am sure that with some rewording you will come up with a very good list. Remember old T is there with you to help you through this. It will be a chance for new T to see how you and old T work together. At the end of this first session you might want to ask new T to tell you how she works with her clients and what changes you might expect.
At your 2nd transition session I think new T is going to be the lead T with old T there to support you and help you with adjusting to the different (if any) ways new T does things. You will be in new T's office so you will see where you are going to be and get comfortable with the space. I would hope that new T will gathering information so she can give you a better idea of what her treatment plan will be for you.
I think the 3rd session is a chance for you to experience what future sessions will be like with new T. Then you are going to have time to say Goodbye to old T.
They are going to hard sessions for you but I think you have a lot of people here rooting for you. I know I am!
