The Dreaded Tranny Pan Leak

No shock there. You used a generic gasket. You sprayed some crapola onto it. You didn't hit the holes up away from the trans. I think I might remember a time or two that a filter kit or rebuild kit came with a Duraprene gasket. It used to bother me to throw away brand new pan gaskets, but they're worthless on a tin pan if they're not Duraprene. The gasket will be either black or reddish brown and will have the word "Duraprene" stamped on it. Just my humble opinion..
