Use ATF-RTV instead of regular RTV sealant. It's specifically engineered to repel ATF. GET THE MOPAR ATF PAN GASKET! It's great! USe it with ATF-RTV (black) and you'll never see a pan leak again. Trust me on this one guys... I've pulled that pan more times than I can count and I must say the re-usable gasket is worth every penny I spent on it!
