Well, i haven't posted since my check-in,but, have enjoyed reading about all your adventures. Now it's my turn. Yesterday afternoon I'm going to work and pull out on a main arterial here (45mph) and half way though second gear I get a huge BANG and my transmission is dead. No reverse- no drive in any gears. My Avalanche has 9000 miles with a Radix. I call a tow and when they try to unload my truck off the flat bed it won't roll backwards! Any ideas on what might have let go and what kind of hastle should I expect from the dealer? Thanks!
