Leaking transmission fluid through this hole(?).
I have a 1997 chevy 1500 4.3 which has 4l60e. I notice a small puddle underneath and its transmission fluid. It appears as though it might be coming from this hole. Is this hole supposed to be there?

Some fairly recent history:
Several months ago, transmission fluid had been puking up and out of the dipstick tube. Online research led me to go ahead and blow the lines out that go to and from the radiator. After that, all seemed fine and good. I'd been driving it around for a few weeks then all of a sudden, I noticed a puddle underneath. I had been looking often so i know it just started leaking.
I am wondering what could be causing this? Maybe i should blow the lines again OR do something with this hole (vent tube), OR tight that bolt next to it? I would like to hear any ideas to further investigate and remedy this problem. Thanks.

Never heard of blowing cooling lines. So, possibly if you blew air through the cooling lines, you could have blown the vent line off the transmission by pressurizing the tyransmission

I'm close to 500,000 miles (2nd motor and tranny)and i have done all the basic maintence. I would think I surely would have noticed something missing, like the vent line by now. But then again, i have not mess with my transmission. My transmission guy has retired and I don't want to, nor do I have, the money to shell out on this old truck for some new person to look at it.

Since blowing the lines with them attached to the transmission worked (stopped the fluid from coming out the dipstick tube) a while it stands to reason that perhaps undoing them from the transmission and blowing them out again may at least buy me some more time. if that doesn't work I suppose I'll drop the pan and go from there. Any other ideas or thoughts I welcome.
