Default oil Leak!?!

Hey guys, I found an oil leak on my 04 RCSB 4.8L with a 5 sp the other day. Theres oil dripping from under the trans where the vents are and on the starter bolt. Anyone seen this before or have a idea of what might be leaking? I put some engine oil dye in, just have to wait for the special light needed to find it. Thanks for your help.

Im betting its the oil pan, but I have seen the cam sensor leak and run down making it look like the oil pan too. You did the right thing by using dye. Get a black light and some yellow glasses and trace it down that way. look as far up the backside as you can
