Yep, I pulled it back out and found the groove. Someone had filled it with some sealer and it was so smooth and gray in color that I missed it. I put the o ring in the groove and reinstalled. I will see if it leaks now. This time I put a pan under the tail so I won't lose another $4 in fluid over night if it leaks again. Thanks for the help.
