Default LS1--back of oil pan leak

Went to change the oil today, jacked up the car and found there was already oil on the floor. It's leaking from where the pan meets the trans, right behind the filter. I ended up changing the oil and wiping it clean, checked an hour later and there was another drop hanging off of the pan. It is definitely engine oil, not trans fluid. Is this going to be a huge bitch to fix?

Edit...I checked all around the valve covers, and it is definitely coming from the back of the oil pan.

Removing the tranny is almost a certainty. Most likely the rear main seal.

Well crappola.

My 4l60e is getting tired anyway, I'll just wait and put a built trans in and get it all fixed at the same time. So sense in pulling the trans to fix the leak and then pulling it again a month later.
