Well, the reason i ask is because I drained/refilled my tranny yesterday but when I was draining, I wasn't draining at temp so I think i may have overfilled the tranny. Now I have a leak there. I alwasy had hanging drops there that never actually dropped to the floor but now I have several drips from that area.

I didn't have time to investigate today, maybe tomorrow but I think it might be ATF...of course oil and new ATF mixed with old dark ATF look the same.
