1998 Chevy Lumina 3.8L V6 leaking transmission fluid out of a vent or breather.

Asked by Nov 23, 2013 at 12:06 PM about the 1998 Chevrolet Lumina 4 Dr LS Sedan

Question type: Maintenance & Repair

I'm not sure the exact part name or what it is but my car has been leaking transmission fluid out of this little relief vent or breather. Everyone keeps saying it's over filled but it started leaking when I didn't even add fluid to it. I changed the filter out and that didn't work and I bought a Haynes repair manual for this car and it says either the drain-back holes are plugged or the vent is plugged. Where are the drain-back hole located on this car and how could I replace this vent? I tried screwing it off but it must be compressed so it cant come out.

First thing to check is the trans cooler and the lines, make sure they are not plugged or damaged, the only way I know as to why you are seeing fluid coming out of the vent is the trans is overheating.
