Adjuster came out and approved the replacement of the transmission. Apparently, they have their own stock of 6L80s and will be sending one to the dealership on Monday. Interesting huh? Of course, since GM is not providing it, the only warranty it will have is the balance of the one my daughter purchased when she bought the truck. The company is called APEX if anyone is wondering. Do not know about the torque converter or testing of the transmission cooler. If I understood correctly, they are also replacing the coolant reservoir and maybe the exhaust manifold bolt and providing a rental car for 5 days. My wife likes getting involved in this stuff so I'm just an observer and advisor on this one! LOL
