New LS1 Owners - Newbie Tech - RPM's hang on 1-2 Shift???

Once in a while, while shifting to 2nd from first, say I shift at 3000 RPM, I put the clutch in and shift to second, still keep the clutch in and the revs stay at 3000 for a few seconds.....and my foot is off the gas. How can it hold the RPM??? Is this a sign of something bad?

Thx for any help/info

mine does it too sometimes. ive never thought about something being wrong though.

The computer will hold it there for a second or two. Why? Maybe to help with the shift, i.e. hold the rpm so as to not clunk. I've notice sometimes under lite acceleration the rpms drop too quick and I get a clunk if I don't pay attention. Emissions, to help keep the fuel mixture from getting too rich when letting out. Those are my guesses.

Mine does it too and I'm glad, I can shift so much quicker and with less effort and it will still be smoother then when the revs fall back down so fast.
