I've got a '96 Sonoma with manual trans and 4.3 v6. Yesterday I noticed it was dripping antifreeze so I jacked it up and saw it was leaking down thru the Bell Housing of the trans. I can't see any leakage coming from the back of either head; but its hard to tell because their so close to the firewall. Is there maybe a freeze plug on the back face of the motor where the bell housing mounts? What even wierder is I drove it this morning, parked it in the garage and its not leaking! (Yes I added antifreeze last night so don't go there ) Any opinions??

That's why I stated NFB (non f-body related) in my subject line....
