This leak has me stumped. It is leaking from what looks to be a capped fitting on top of the transmission. When I pour water into the overflow tank, it immediately leaks out of the capped spot on the transmission. I followed all hoses and none go to this spot. I had to take the intake off to find the leak, it looks like there is a metal cap on top which has dislodged enough to let water leak out, I can stick a screwdriver back in there and move the cap round and round on the fitting. It is about the size of the tip of a pinkie finger. Anybody know what that is and how to fix it?
