Stability link light is on and the car jerks into gear and it is leaking oil

What is your question?

I looked under the car and the oil leakage was all over the oil pan but there were no visible cracks and I couldn't tell where the leak was coming from and it isn't on anything else not even the oil filter and whatever gear I put it in it jerks hard

What makes this problem better or worse?

Once you start driving it it starts to smoke a little from under the hood from the oil leakage

How long has your 2006 Cadillac DTS had this problem?

Don't know how long this problem has been going on because I just bought the car today used
