You might try cleaning it off real good with some brake clean and blowing it try. Then use some spray foot powder or tracing powder and spray all the areas above where you see the leak coming from. It should give you a good indication of where you leak is starting at. Good luck !!!!
first of all.... pan finally installed successfully, no leaks. AND HAMB'r Roadsir has great advice. So.... had a crushed steel pan and bought a aluminum one from Speedway that came with a thin rubber gasket (first mistake). Installed it, and filled with fluid. drip, drip, drip. ****! Dropped the pan, douched the gasket in RTV and reintalled the aluminum pan and filled with fluid new.... LEAK, LEAK, LEAK! ****! Dropped the pan again, s****ed off all RTV and cleaned pan and trans surface to "better than new". Bought a spendy Moroso silicone and steel gasket from Summit and reinstalled and filled with more NEW fluid.... . Did not heed the warning from ROADSIR and cracked the pan in the front corner (by using a large head allen and torquing too tight. CRACK! then LEAK, LEAK, LEAK. ****! OK... time to get smart (finally) Dropped the pan (yet again), drained the fluid for reuse (afterall, at this point, its been flushed soo many time, the fluid is clean), welded the crack in the pan, cleaned everything, reinstalled (did not over tighten) and filled with fluid. FINALLY.... No ****! The leaky trans pan is fixed. Now its time to move on to my engine cooling issues.
