Device does what it claims to do; prevent vehicle from shifting into V4 mode. This doesn't completely stop the annoying vibration that occurs between 1000rpm and 1250rpm. I believe there is some other inherent deficiency that Chevy can't diagnose or chooses not to address. This vehicle should not vibrate or shudder at a certain rpm.
