2008 Buick Enclave Transmission help

What is your question?

2008 Buick Enclave 3.6L V6 A few days ago I got home and made something to eat. After I was done I got on my car and the problem erupted. The car started and moved a little for like a minute and then it just didn't respond. If I turn it off and then turn it on it moves for like another minute but then it stops responding. Rinse and repeat. It stays on but it won't go forward or backwards. It won't move. I used a scan tool and it said something about some Solenoids being Stuck On and Stuck Off plus something about the Speed Sensor having no signal but I'm not too knowledgeable on the subject. I've taken out and put in some transmissions before but I haven't actually messed with them since I have no idea how they work. What can I do to fix it? Thank you in advance.
