Im getting an occasional smell of tranny fluid in my vents when I come to a stop. Recently I saw some fluid around a cap on what I assume is the transmission. Its a small black cap just right of the are filter. Anyone know what the cap is too? Or why it'd be letting fluid up?

not sure where that is, usually the dipstick leaks fluid out if its old.

Hmmm good point. Ill order one up in the next week. I know its the original so very likely. Ill grab a photo of the cap i am speaking of tomorrow.
I know nothing should go in it, but the fluid smells like tran fluid. I think it did haha.

The little cap is inside a sort of triangle. That triangles points being the air filter, the radiator, and the dizzy. its just a tiny as black cap.
No idea what its too so i am more curious than anything what it is.
