I had the Duramax to my local service garage today for an oil change. While waiting for the oil to drain, Rick the service man (my buddy) checked over the underside of the truck. He found a wet transmission line (clamps and rubber hose) around the front end. I called the dealer and dealer said that they have been having a problem with them and ordered all 3 lines. Said that changing them is an all day job. Good job , Rick!! Glad he found the leak before we left on a two week excursion to Florida (without the Monty). Now if only the parts arrive before we leave. May have to drive the other Chevy (Monte SS) in the stable.
Also mentioned to the dealer about the intermediate steering shaft acting funny and that will be also addressed. Then, I mentioned about the rust on the rear bumper. That, he said, will be checked when he sees the truck.
All this and only 10,100 miles.
