We deal with a lot of members who wish to DIY and does not have enough experience or knowledge so it is nothing to worry about. We would try our best to help you get the problem solved.
However keep in mind that without the physical vehicle and actual symptoms, we depend on you to provide the necessary information and if any information is wrong or missing, that would hamper and cause complications.
I did some research and information indicates your transmission model should be 5R55E.
Code readers are rather cheap but scan tools are expensive so you can't blame the dealer for charging you an arm or leg.
