On page 437 of your 2007 owner's manual, it says to change the engine coolant at 150K miles, or 5 years, whichever comes first. It does not mention the differential fluid.

On my C5 I used to change the diff fluid every 20K miles. Never hurts to change it more often than the manual says. For me it was free except fluids. My son-in-law has a lift in his garage and knows C5 and C6 Corvettes real well.

On my 1998 Camaro, there was a recommended diff fluid change mileage.
Is the C6 dif really better, or is GM simply trying to make the operating costs look better?
