I just bought my C7 and just had the transmission flushed because of a shutter which I hope clears the issue. I read about a device called a Range which would force the transmission to stay with 8 cylinders instead of dropping to 4 at slower speeds and wondered if this would help with shutter I need some good reasons why the Range would be a good thing to buy. I couldn't find any posts about the Range. Has anyone used the Range that cares to comment?

Tons of threads on this and other forums. Haven't seen any that were dissatisfied. Only buy from Range Technology direct. About $180 with running discount and free shipping. They offer free lifetime system updates. Others selling the product on other internet sites are not endorsed by Range and they do not offer system updates if there are any.
I've had mine in for about 6 months and 4400 miles and no issues. No battery drain whatsoever.
