I'v had this tiny leak for awhile now on my Accord (88,000 miles). I can't tell if it's coming from the case the axle shaft seal. The axle shaft seal was wet with fluid, and I'm wondering if it's leaking from there and running down to the bottom of the transmission case? In the picture you can see the oily trail coming from the seal down the side of the transmission case (although I wiped away most of it,it's still visible).
It's not severe enough that it drips onto the ground though. It's more of a weep than a leak. I'm sure the answer is "no",but do any additives exist that can be put into the transmission to condition the seal to stop the weeping that won't adversely affect the transmission?
