We really don't know much other than it is leaking off the tranny case and onto the exhaust. From there it fumes up the sides of the car, behind the intake, and into the interior. I haven't had much of a chance to drive it, so I can't really tell you where exactly it leaks from on the tranny, but I do know it can not be from the shifter gasket, since that was very recently replaced.
If it smells similar to tranny fluid, and it's white. Then it is. We all just need to figure out exactly where it's leaking from and how to fix it.
I thought maybe it was an overflow type deal, since I just replaced my transmission fluid, and thought I may have put in a bit too much.
