I have a leak and it seems like it’s coming from this. I’ve cleaned it off a few times both around it and a little lower not in picture, of this rubber piece by where the transmission connects. Anyway what is it? How do I seal it? Thanks guys
Mine does this too. Probably a result of the high mileage and age means some atf will seep past the seal. Unless it is a big leak it would not be worth removing the transmission to get to.
I just degrease and clean it every oil change.
That's an inspection hole cover. What fluid is it leaking? Brown or red? Brown would be engine oil and a leaking rear main seal. Red would be tranny fluid and a leaking pump seal. Sealing that hole won't stop either.
