Like RRR and SR said about the bolt holes in the pan. But DON'T just make the pan flat; dent the holes away from the trans; that way they'll prestress the area between the bolts. NEVER use a cork, cork/neoprene, neoprene, or rubber gasket. You have to find the DURAPRENE gasket; about $3.50. And NO SEALER! Clean and DRY surfaces.
