Oil leak in oil pan gasket on 2001 Oldsmobile Aurora

I have an oil leak in the bottom of the engine, and it appears like it is the gasket around the oil pan. I s an oil leak common in the Cadillac motor that is placed in this car?

The engine in your 2001 Oldsmobile is of the same design as the 4.6L northstar engine used in the Cadillac models. The Cadillac engines are know for oil leaks from the upper crankcase oil seals. I would not be surprised if the 4.0.L engine suffered from the same oil leak issue.
my leak is coming from the pan gasket. Do i haveto dropthe transmission?
