It is not recommended to use any sealant cuz if even the tiny piece of silicone/sealant gets into the trans. side, it could get tangled in the intricate parts of the tranny and cause issues. I need to clean the whole area again and run it to pinpoint because that pink fluid spreads so easily especially when it is warm. Will follow-up again once I get some time to get back under there! Thanks for the feedback gang!
