Picked up the truck Friday, Told the service dept I wanted to see the damaged case and found the same problem that "newbie" showed in his pictue
I did talk to the service manager and he said to give GM a call and see if they would reimburse me for the 1/2 that I had to pay. Looks like this could be a series problem if not found before a long trip, with in a 50 mile trip I lost about a 1/2 qrt. the case only holds 2 qrts.
