now i know about te rear main's going sometimes, and this may be it. but i ceratinly hope not! but what else could be causing a leak in that area? it is dripping for sure after driving it. this just started last week or so. lookin at it, it seems wet up near the driver side exhaust, toward the rear, and on the pass side, up to what i assume is the starter, and obviously on the bottom front of the tranny. could it be something else, and if it a rear main, (just so i can get a good scare and get my heart beating) whats it cost to fix?
