I would definately take a closer look at your side cover. The second torx head bolt to the left from the RIGHT lower side of the cover is a very common weak area to crack if the bolt gets tightened too much and it will cause a pretty bad leak. I would take a can of parts/brake cleaner to the area and see exactly where it is leaking from so you know what you are getting into. Unfortunately changing the side cover or the gasket means dropping the drivers side craddle and lowering the transmission down until there is enough room to remove it.
