I have had several LS1 cars through the years but never any with a leak until now. I recently purchased a 2002 SS Convertible with an automatic. After driving the car a short distance I noticed oil drips coming from in between the oil pan and transmission. The car has only 80,000 miles on it. I decided to tear into it a couple weeks ago. I ended up replacing the rear main, rear cover, oil pan, valley cover, intake gaskets. I also replace the knock sensor seal and the oil pressure sender.
I thoroughly cleaned everything while I had the engine out so there is no chance of of residual oil, but I still have a leak. Does not seem to be as bad but it is still enough to get the front lip of the transmission wet at the bottom.
I have seen several threads about the freeze plug in the crank leaking but that only seems to leak on car that are manuals and damaged while removing the pilot bearing. Could this be a problem with automatics?

I did not put any sealant on the fly wheel bolts, should have I? Did not appear there had ever been anything on them.

The only other thing I could think of is the Cam sensor o-ring but what are the chances of that being bad?

Any advice would be appreciated
