There might be a vent up there. I had a firebird that would leak from the top of the tranny when it got hot. Turned out it was coming from a vent. Not the same tranny but maybe they all have vents.Well i think we can rule out the rear seal its not leaking from the tail shaft area, its leaking from the top of the transmission. I was up under the stang and noticed there looks to be an accesss hatch under my console..... any ideas why the factory put that there? It looks as if its leaking from the trans in that area. Is there a sensor there?
Possibly, but in my case I believe it was overheating as it only did it after long hot drives. Is it leaking from the tailpiece by where the speedo sensor is? Mine is a little wet there but no drips or anything. I was just under there today tightening my exhaust to the cat flange.Thanks so if it was over full it may leak out the vent?
