Hi Jeff. Yes. It's an eco device which plays a part in the Corvette not being saddled with the US gas guzzler tax. That being said, it's not quite as controlling as it sounds. My C6 had this feature and the fellow I had bought it from had purchased the little electrical in-line dew-dad (that's not the GM part name) that overrides it but had never installed it. I never installed it either. For the almost three years I drove the car, it never forced me to shift from first to fourth once. I thought it didn't work so forced myself one day to drive like my late grandmother.... 5 kph in first...then a 30 second slooooowwwww shift towards second gear.... and yup... it guided me right into fourth.... Now I'm not a super aggressive driver either so I'm not really sure what the big deal about it is.... And yes.... If by chance this does bother you, it's a cheap fix.......Better yet, If you buy a C6 that's compatible with my 2009 LS3, I will send you mine... I forgot to include it when I sold my C6 and still have it in my file cabinet......
