My '12 6R80 is losing coolant via the coolant line to transmission casing connection. The bracket seems tight, but I can wiggle the lines and there is fluid all over. Search has not turned up ANY information about these transmissions leaking from that spot. Plenty bulkhead connectors and front sump seals leaking, but nothing from the cooler line.

Has anyone else had this problem? What was the fix? Would new O-rings fix it?
