First check your fluid to see if it's brown or black, if black the trans is toast, if brown it stil may be repaired. Scan for codes to see if you get anything on that you may need a trasn shop to do that but it sounds as if it's a valvebody/internal clutch problem. You cold also have a cracked case internally.
