Use MPH to set your shift points, not RPMs. And command it before you actually want it to shift at. The shifting looks at MPH first. Example..you said you have your 2>3 shift at 60mph and 6200 rpms...and you saw it rev to 6700. that 6200 meant nothing.

Thanks, that all makes sense now that you explained it. Was worrying about the RPMs for nothing.
Makes me wonder why GM wouldn't program the manual mode like this from the factory. Seems like it would be better than forgetting you are in manual mode and not shifting. Seems like it would be easier on the motor.
