    I have a small leak on my trans rear seal like just a drip every 10-15 minutes at idle and underload don't seem much more trans fluid isn't low at all. I know i should just fix it but you know i did i changed the trans seal and it still leaks. yoke is perfect output shaft no play oiled yoke when putting it in. So I'm not doing it again. but the oil is leaking on the cats ( X-pipe) and stinks. So I'm going to put a heat shield on the cats how hot do they get?

    Once they're operational they reach around 1500*.

    Same thing happened to me. Man it stank and smoked like crazy. It will only get worse, just replace the seal again.
