I feel for you buddy. My first priority would be to get the car OUT of there they are guessing and fooling around with things they know nothing about.
There is a good chance they will cause more damage. I would insist the car be brought to a qualified shop for repair. It sounds as if they have been fooling around a while now and occassionally stumble into a little luck. Maybe call the local dealer and ask them to bail you out.Perhaps they will extend a discount to the trans shop. If the dealer guys will help out maybe Aaamco will be glad to be rid of it.They could be on the hook for some very expensive parts if they do it wrong. The dealer will have it going in minutes I'm sure.
Lots of people love to rip the "stealer" but aside from the salesmen and some of the service writers the techs are there to help you. Try to deal with a tech or a writer who has worked with the tools.
Good Luck keep us posted
