Please help!! we have an 04 Duramax that has a knock and is leaking anti freeze... I heard something about a torque converter on another forum, and our mechanic is wondering if its a head gasket?? He said its leaking from that area but we heard thats extreamly rare. we took it for a pressure check and they said their were no leaks.... What is a girl to do???
Thanks!!

Where's it leaking - front, rear, left, right?

Where's the knock - front,rear, left, right?

Who are "they"? (that say it's rare)

Does your mechanic usually work on the Duramax?
