Trans leak up front

Usually a bad seal as mentioned, but SOMETIMES the converter snout cracks at the lugs where it engages the front pump OR around where it's welded to the converter. So I would LITERALLY take a magnifying glass to the WHOLE conver snout everywhere on it and look for cracks. Also too, just because you don't find any doesn't mean it's not cracked. So, unless you find a smoking gun seal, it might be a good idea to have the converter checked out by a reputable shop.
