Dan, I'll research this further and will be back to you shortly. Haven't heard about and nor did I ever experience any leaks with the C7 (bought new, just sold, 40K miles). Lemme see what I can dig up.

Has anyone needed to have the transmission fluid changed because of moisture in it? I have had reports of that in 14 to 18's. Also converters needed to be replaced. I have just bought a 15 with 11,000 miles and it has that transmission chatter. Any ideas? Thanks, Dan Fischer.
