.....they all should have one..its on the topside inbetween shifter housing n like bellhousing ..its a plastic tube wit a little cap that is a total pain to pop off while under the car...im hoping i just overfilled sumhow...any other options? i replacedthe rearseal everythings tight i dunno wat else but the breather spittn out excess since once hot it expands..?
??? the breather on my wc t5 is a small like 2 inch plastic tube with a cap that sits loosely on top of the tube.. right by the top plate of transmission that u can unbolt...so i've filld a t5 before an never had this problem..i only unscrew top plug an pump til it starts coming out on its own..but if i did overfill the smoking/leaking should soon stop i would assume..as long as i dont keep refilling...but if thats not y im leaking ima just run the rebuilt trans to the ground since low oil uhgg! ...the rebuilt i just bought an my old broke trans both had same breather tube wit loose cap in same spot..
That sounds like a breather, its just that the t5s do not use a pump (as most any manual tranny), they simply dip the gears in the fluid and trace it through the grooves. I would just remove that plug and see if anything comes out, if not then...I don't know, the only thing I could think of is it splashing the fluid up through there but why I don't know.
