Uh heres an example, I start the car up in the morning and wait half a minute. Then I put the car in reverse to get out my driveway, as soon as I put the car in reverse a loud clank noise happens. It just makes this noise every time I switch it to reverse. I notice RPM drops and sometimes the car would slow down or stop a bit while i'm reversing. When it slows down I notice my TCS Off light then begins to light up, not always but most of the time.
EDIT: Regular driving feels perfectly fine, I dont notice any slips or hard shifts.
