Default Can the car down shift while using paddle shifters

While using the paddle shifters under rapid acceleration after shifting from 1st to 2nd while staying on the throttle in 2nd gear my RPMs spike rapidly. It feels like an automatic when you punch the gas and the RPMs drop and you get a burst of power, but this is when the paddle shifters are in use. I don't feel the tires slipping. I'm thinking the car is downshifting on its own, but that dosent make sense. I have a 09 LS3 and its bone stock. Is this normal or should I be concerned?

You are in charge of shifting with paddles. You have wound it tight in second and time to up shift to third gear. Wind it to shift to fourth and so on.

Down shift on the way down.

What do you mean by winding it in tight?

your rapid rpm spike !!! Bit farther bout 6500 RPM and you hit rev limiter.


You do understand paddle shifting is as close to manual trans as you are going in a auto.

What could be causing it to spike?
I'm aware of the rev limiter. I know I didn't hit it. Rpms weren't high enough

Not riding with you but with your foot in the fuel the RPMS will increase So up shift the trans and rpm will decrease,


SHIFT .... IMHO

If you are not in "S" mode it will shift automatically while using the paddles.

The car is in S mode. I recently learned the car only does it when I first start driving. After driving for a bit it stops doing it

My guess is that the torque converter isn't locked up since the trans isn't warm yet.

Is that something I should be concerned about?

I do not understand what you are trying to say. Can you re-word your question as to tell us what s happening with different terms. My car only down shifts without my help when I am slowing or breaking and come to a stop.
